The individual mass of C, H and O in given sample are 0.5196 g, 0.0374 g and 0.1979 g respectively.

Moles of CO2 formed can be calculated as

= Mass of CO2 / Molar mass of CO2

= 1.9061 / 44 = 0.0433 moles

Now, moles of C which is present in one mole of CO2 = 1 mole

Moles of C in 0.0433 moles of CO2 = 0.0433 moles

As we know that, molar mass of C = 12 g / mol

Mass of C in 0.7549 g of given sample can be calculated as

= 0.0433 × 12 =0.5196 g

Mass of H2O formed = 0.3370 g

Similarly, Molar Mass of H2O = 18 g / mol

Moles of H2O = 0.3370 / 18 = 0.0187 moles

Moles of H present in 1 mole of H2O = 2 moles

Moles of H present in 0.0187 mole of H2O = 2 × 0.0187 = 0.0374 moles

Molar mass of H = 1 g / mol

Mass of H contained in 0.7549 g of sample = 1 × 0.0374= 0.0374 g

Mass of O in 0.7549 g sample can be calculated as

= 0.7549 – [(Mass of C ) + (Mass of H) ]

= 0.7549 – [ (0.5196) + (0.0374) ]

= 0.1979 g

Thus, we calculated that the individual mass of C, H and O in given sample are 0.5196 g, 0.0374 g and 0.1979 g respectively.

The molarity of the solution is approximately 3.06 M when 5.20 g of HCl is added to enough distilled water to form 3.00 L of the solution.

To calculate the molarity of a solution, we need to know the moles of solute and the volume of the solution in liters.

Given:

Mass of HCl = 5.20 g

Volume of solution = 3.00 L

To convert the  HCl mass to moles

Moles of HCl = (Mass HCl) / (Molar mass HCl)

= 5.20 g / 36.46 g/mol

= 0.1426 mol

Next, we divide the moles of HCl by the volume of the solution in liters to find the molarity:

Molarity (M) =   (Solute Moles)/ (solution Volume)

= 0.1426 mol / 3.00 L

≈ 0.0475 M

To express the molarity with the correct significant figures, we can round it to three decimal places:

Molarity ≈ 0.048 M

Therefore, the molarity of the solution formed by adding 5.20 g of HCl to enough distilled water to make 3.00 L is approximately 0.048 M or 3.06 M when expressed to two significant figures.

The molarity of the solution is approximately 3.06 M when 5.20 g of HCl is added to enough distilled water to form 3.00 L of the solution.

When the child sits on the partially filled balloon, the pressure of the balloon increases. The pressure change is a doubling of the initial pressure, indicating a factor of 2 increase.

When the child sits on a partially filled balloon, the volume of the balloon decreases by half. According to Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature, the pressure inside the balloon increases.

Let's consider the initial volume of the balloon as V and the initial pressure as P. When the volume decreases by half, it becomes V/2. Since the amount of gas remains constant, the pressure increases to maintain equilibrium. The new pressure can be denoted as P'.

According to Boyle's Law, P₁V₁ = P₂V₂, where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume. Plugging in the values, we have P * V = P' * (V/2).

Simplifying the equation, we get P' = 2P. This means the pressure of the balloon increases by a factor of 2, or it doubles. So, the pressure change can be expressed as an increase of two times the original pressure.

Answer:

How acidic or alkaline a substance is.

Explanation:

1 = Strong acid e.g. Stomach acid

7 = Neutral e.g. Water

14 = Strong alkaline e.g. Sodium hydroxide

Increase HCI concentration and raise the temperature to speed up the reaction rate between magnesium and hydrochloric acid.

To speed up the rate of reaction between magnesium and hydrochloric acid, two possible changes can be made:

By increasing the concentration of the hydrochloric acid solution, there will be a higher number of HCI particles in the reaction mixture.

This will result in a greater frequency of collisions between magnesium and HCI molecules, leading to an increased rate of reaction. The higher concentration provides more reactant particles available for successful collisions, promoting faster reaction kinetics.

Raising the temperature of the reaction mixture increases the kinetic energy of the molecules, making them move faster.

This leads to more frequent and energetic collisions between magnesium and HCI particles, facilitating successful collisions and increasing the reaction rate. Additionally, an increase in temperature also enhances the reactivity of the molecules, allowing for more effective bond-breaking and bond-forming processes during the reaction.

Both of these changes effectively speed up the reaction rate by promoting more collisions between reactant particles and providing them with sufficient energy to overcome the activation energy barrier.

Fe and S are already balanced in this equation

Balanced indicates that the number of elements in question has the same number of atoms both on the left side (the number on the reactants side) and on the right side (the number on the product side)

Even though one of the elements is said to be balanced, the chemical equation as a whole cannot be said to be balanced, because the chemical equation has several components of the constituent elements.

To balance chemical equations, a coefficient in front of the compound is usually added either in the reactants or products

Reaction

FeS₂ + Cl₂ → FeCl₃ + S₂Cl₂

From this equation, it can be shown that: the Fe and S elements are balanced because the numbers are equal both on the left and right, while the Cl elements are not yet balanced

Fe, left=1, right=1 ⇒ balanced

S, left=2, right=1 ⇒ balanced

Cl, left=2, right=5⇒ not balanced

For balanced equations:

Explanation:

The difference between atom and molecule can be drawn clearly on the following grounds:

  Atom is defined as the smallest unit of an element that may or may not exist independently. On the other hand, molecule implies the collection of atoms linked together by bonds, indicating the smallest unit of the compound.

   Atoms may or may not exist in the free state, but molecules exist in the free state.

  Atoms consist of a nucleus (containing protons and neutrons) and electrons. In contrast, a molecule consists of two or more identical or different atoms, chemically combined.

  The shape of an atom is spherical while molecules can be linear, angular or rectangular.

  Atoms are highly reactive, i.e. they participate in a chemical reaction                  without additional decomposition into subatomic units. However, this does not apply to noble gas atoms. In contrast, molecules are less reactive, as they do not participate in a chemical reaction.

  Atoms possess a nuclear bond, as it entails an electrostatic attraction between the nucleus and the electron. In contrast, there exists a chemical bond between the atoms of a molecule, hence it consists of single, double or triple bonds.

Answer:

Atoms are the thing that makes up molecules and compounds. Molecules contain two or more atoms and are held together by covalent bonds, whereas compounds are held together by ionic bonds. Two or more elements bonded together through ionic attraction.

The root mean square speed of Cl₂ molecule is 11.34 cm/sec.

Solution

We need to calculate the root mean square speed of Cl₂ molecule.

Average kinetic energy = RT

where,

R = Molar gas constant

T = absolute temperature in Kelvin.

Given,

Average kinetic energy = 4570 J/mol

R= 8.314 J/mol/K

So, T = (4570 × 2)/(3 × 8.314)

⇒ T = 366.45 K

Root mean square velocity = √(3RT/M)

For, Cl₂ molecule,

M = 71 g/mol

T = 366.45 K (as condition is same as previous)

Therefore, Root mean square velocity = 11.34 cm/sec

Hence, Root mean square velocity = 11.34 cm/sec.

The volume/volume percent of a solution prepared from 10. 0 g ethanol in 95. 0 g water is 9.29%.

Given the mass of ethanol = 10g

The mass of water = 95g

The density of ethanol = 0.789g/mol

The density of water = 1g/mole

volume can be defined as mass of solution by its density.

The volume/volume percent of a solution can be calculated as:

V/V% = (volume of solute / volume of solution) × 100

Here, the volume of the solution can be calculated by adding the volumes of ethanol and water together such that:

Volume of solution (Vs) = volume of solute + volume of solvent

(10.0 g ethanol / 0.789 g/ml) + (95.0 g water / 1.00 g/ml)

Vs = 12.7 ml + 95.0ml = 107.7 ml
