Answer:

In this reaction, the hydrogen from the HCl is taken up by ammonia.

NH₃ (aq) + HCl (aq)  ----> NH₄⁺ (aq)  + Cl⁻ (aq)

In this reaction, ammonium (NH₄⁺) is the acid and the chorine ion (Cl⁻) is the base.

When acid and base combine then formation of salt take place and the reaction is called neutralization reaction. Hence the balanced equation is NH₃(aq) + HCl(aq)  \(\rightarrow\)NH₄Cl

Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side. The principle behind the balanced equation is the conservation of mass that is mass can neither be created nor be destroyed.

Since, HCl is acid and NH₃ is base so H⁺ will be transferred from acid to base

The balanced equation is

NH₃(aq) + HCl(aq)  \(\rightarrow\) NH₄⁺(aq)  + Cl⁻ (aq)

Cl⁻ and NH₄⁺  combine to form salt ammonium chloride

Here NH₃  is Lewis base as it can donate its lone pare of electron to H⁺ coming from acid and HCl is a Bronsted acid as it give H⁺.

Hence the balanced equation is

NH₃(aq) + HCl(aq)  \(\rightarrow\)NH₄Cl

A chemical property is a characteristic of a substance that is observed during a chemical reaction, as opposed to a physical property, which is a characteristic that can be observed without altering the substance's chemical makeup.

A detailed explanation:

Chemical properties describe how a substance reacts with other substances. For example, a substance's flammability, or its ability to burn, is a chemical property. Other examples of chemical properties include a substance's reactivity, toxicity, and acidity or basicity.

Chemical reactions involve changes in the chemical makeup of a substance, and these changes can often be observed through changes in color, temperature, or other physical properties. For example, when iron rusts, it changes from a shiny silver color to a dull red-brown color, indicating a change in the chemical makeup of the iron.

Chemical properties can also be used to identify a substance. For example, a substance's reactivity with certain chemicals or its ability to conduct electricity can be used to identify it. Additionally, the chemical properties of a substance can be used to predict how it will react with other substances.

It's important to note that chemical properties are different from physical properties, which are characteristics of a substance that can be observed without altering its chemical makeup. Examples of physical properties include a substance's color, density, and melting point. While chemical properties describe how a substance reacts with other substances, physical properties describe the substance itself.

The limiting reactant is Na .There will be 0 mol Br2 left over at the end of the reaction.

In order to determine the limiting reactant, you need to compare the amount of each reactant present to the stoichiometric ratio of the reaction.

The reactant that produces the smallest amount of product is the limiting reactant. Here's how to do it for the given reaction:

2Na(s) + Br2(g) → 2NaBr(s)

Part a:

5 mol Na and 5 mol Br2

Step 1:

Write the balanced chemical equation for the reaction.

2Na(s) + Br2(g) → 2NaBr(s)

Step 2:

Calculate the amount of product formed from each reactant, assuming all the other reactants are present in excess. We will start with Na.

Using the stoichiometry of the reaction:

2 mol Na reacts with 1 mol Br2 to produce 2 mol NaBr.

So, 5 mol Na will react with (5/2) × (1 mol Br2/2 mol Na) = 1.25 mol Br2

The limiting reactant will be the one that produces the least amount of product. Therefore, the limiting reactant is Na.

Step 3:

Calculate the amount of product produced from the limiting reactant. Now we know that Na is the limiting reactant. Using the stoichiometry of the reaction:

2 mol Na reacts with 1 mol Br2 to produce 2 mol NaBr.

Therefore, 5 mol Na will produce (5/2) × (2 mol NaBr/2 mol Na) = 5 mol NaBr. So, the limiting reactant is Na, and 5 mol Na produces 5 mol NaBr.

Therefore, Na is the limiting reactant. This means that there is no excess Na left at the end of the reaction, but there is excess Br2. The amount of excess Br2 can be calculated as follows:

Starting with 5 mol Br2, and using the stoichiometry of the reaction: 2 mol Na reacts with 1 mol Br2 to produce 2 mol NaBr. Therefore, 5 mol Br2 will react with (5/2) × (2 mol NaBr/1 mol Br2) = 5 mol NaBr. So, there will be 0 mol Br2 left over at the end of the reaction.

The following statements on HPLC modes are true is more polar compounds elute first in normal-phase HPLC (Option E).

The liquid chromatography (HPLC) is a technique in analytical chemistry employed for the separation, identification, and quantification of elements. It is considered a highly sensitive method, and it works by separating the components in a mixture with the assistance of a solvent under high pressure.

There are two modes of HPLC: Reversed-Phase HPLC (RP-HPLC) and Normal-Phase HPLC (NP-HPLC). In RP-HPLC, a nonpolar stationary phase, such as C18, is used, and polar solvents, such as water, are used as mobile phases. Polar stationary phases, such as silica gel, are used in NP-HPLC, while nonpolar solvents, such as hexane, are used as mobile phases.

More polar compounds have a greater affinity for the polar stationary phase than less polar compounds, which have a higher affinity for the nonpolar mobile phase in NP-HPLC. As a result, less polar compounds elute first in normal-phase HPLC.

Thus, the correct option is E.

The correct answer is 0.15.

We are aware that there is 0.05 mol of an unidentified hydrocarbon we will refer to as "X" and that its burning produces 6.6 g of carbon dioxide and 3.6 g of water.

These quantities might be converted to moles by applying the following formula:

amount= mass/ relative atomic mass

Thus, the following equation may be written for H2O: moles = 3.6 / 18 = 0.2 and for CO2: moles = 6.6 / 44 = 0.15.

0.05X + x'O2 = 0.15CO2 + 0.2H2O

This may be made simpler by dividing through by 0.05 (this step is likely to be the most helpful to you), resulting in:

1 x + x O2 = 3 co2 + 4 H2O

The hydrocarbon must have been the source of all the carbon in the carbon dioxide and all the hydrogen in the water.

Accordingly, 4 x 2 = 8 moles of H and 3 x 1 = 3 moles of C.

There are 3/1 = 3 Cs and 8/1 = 8 Hs in one X molecule.

Decomposition reaction, also known as analysis or dissociation, is a type of chemical reaction in which a compound breaks down into simpler substances or elements. In this reaction, a single reactant undergoes a chemical change and produces two or more products.

The decomposition reaction can be represented by the general equation:

AB → A + B

Where AB is the reactant, and A and B are the products. The reactant AB is usually a compound, and it breaks down into its constituent elements or simpler compounds.

There are different types of decomposition reactions, including:

Thermal decomposition: It occurs when a compound is heated, resulting in its decomposition into simpler substances. For example, the thermal decomposition of calcium carbonate (CaCO3) produces calcium oxide (CaO) and carbon dioxide (CO2):

CaCO3 → CaO + CO2

Electrolytic decomposition: It takes place when an electric current is passed through an electrolyte, causing it to break down into its component ions. For instance, the electrolysis of water (H2O) leads to the decomposition into hydrogen gas (H2) and oxygen gas (O2):

2H2O → 2H2 + O2

Photochemical decomposition: It occurs when a compound undergoes decomposition due to exposure to light energy. Chlorine gas (Cl2) can decompose into chlorine atoms (Cl) under the influence of light:

Cl2 → 2Cl

These are just a few examples of decomposition reactions. They are important in various chemical processes and are used in industries, laboratory experiments, and natural phenomena. By understanding and controlling decomposition reactions, scientists can gain insights into the behavior of different compounds and develop practical applications in fields such as chemistry, materials science, and environmental science.

The volume of the gas will be 223.6 cm³ at a pressure of 1.1 atm if the temperature remains constant. This was found by applying Boyle's law to the given values.

A sample of gas has a volume of 250 cm³ when its pressure is 746 mmHg.

A sample of gas has a volume of 250 cm³ when its pressure is 746 mmHg.

To compute the volume of gas at 1.1 atm when the temperature remains constant, we can apply the Boyle's law formula.

P1 V1 = P2 V2

This formula describes the relationship between pressure and volume of a gas.

According to the formula, pressure and volume are inversely proportional to each other at a constant temperature. Therefore, if the pressure increases, the volume of the gas will decrease.

To find the volume of the gas at a pressure of 1.1 atm,

we can substitute the given values into the formula:

P1 = 746 mmHg

V1 = 250 cm³

P2 = 1.1 atm

V2 = ?

Note that we need to convert the pressure from mmHg to atm because the units of pressure and volume must be consistent.

Substituting the values:

P1 V1 = P2 V2(746 mmHg)(250 cm³)

= (1.1 atm)(V2)

Convert the pressure to atm:

746 mmHg / 760 mmHg/atm

= 0.981 atm

Simplify: 0.981 atm (250 cm³) = 1.1 atm (V2)

Solve for V2:

V2 = (0.981 atm x 250 cm³) / 1.1 atm

V2 = 223.6 cm³

Therefore, the volume of the gas will be 223.6 cm³ at a pressure of 1.1 atm if the temperature remains constant. This was found by applying Boyle's law to the given values.

When EROEI (Energy Return on Energy Investment) is equal to 1, it means that the energy gained from a particular source is equivalent to the energy invested in obtaining that energy. In other words, the energy return is equal to the energy input. This indicates a situation where the energy extraction process is barely breaking even, with no net gain or loss in energy.

EROEI is a metric used to assess the efficiency and viability of energy sources. It measures the amount of usable energy obtained from a particular energy source divided by the amount of energy invested to extract or produce that energy. A value of 1 means that the energy gained is just enough to offset the energy invested.

In practical terms, an EROEI of 1 implies that the energy source being evaluated is not very efficient. It suggests that the amount of energy required to extract, process, or produce the energy is nearly equal to the energy obtained. Therefore, there is little to no surplus energy available for other uses or to sustain the energy extraction process itself.

An EROEI of 1 is often associated with energy sources in their early stages of development or exploration, where the technology or extraction methods may not be fully optimized. It could also indicate energy sources with high production costs or low energy density.
