Answer:

\(\large \boxed{\text{21.6 L}}\)

Explanation:

We must do the conversions

mass of C₆H₁₂O₆ ⟶ moles of C₆H₁₂O₆ ⟶ moles of CO₂ ⟶ volume of CO₂

We will need a chemical equation with masses and molar masses, so, let's gather all the information in one place.

Mᵣ:        180.16

         C₆H₁₂O₆ + 6O₂ ⟶ 6CO₂ + 6H₂O

m/g:      24.5

(a) Moles of C₆H₁₂O₆

\(\text{Moles of C$_{6}$H$_{12}$O}_{6} = \text{24.5 g C$_{6}$H$_{12}$O}_{6}\times \dfrac{\text{1 mol C$_{6}$H$_{12}$O}_{6}}{\text{180.16 g C$_{6}$H$_{12}$O}_{6}}\\\\= \text{0.1360 mol C$_{6}$H$_{12}$O}_{6}\)

(b) Moles of CO₂

\(\text{Moles of CO}_{2} =\text{0.1360 mol C$_{6}$H$_{12}$O}_{6} \times \dfrac{\text{6 mol CO}_{2}}{\text{1 mol C$_{6}$H$_{12}$O}_{6}} = \text{0.8159 mol CO}_{2}\)

(c) Volume of CO₂

We can use the Ideal Gas Law.

pV = nRT

Data:

p = 0.960 atm

n = 0.8159 mol

T = 37  °C

(i) Convert the temperature to kelvins

T = (37 + 273.15) K= 310.15 K

(ii) Calculate the volume

\(\begin{array}{rcl}pV &=& nRT\\\text{0.960 atm} \times V & = & \text{0.8159 mol} \times \text{0.082 06 L}\cdot\text{atm}\cdot\text{K}^{-1}\text{mol}^{-1} \times \text{310.15 K}\\0.960V & = & \text{20.77 L}\\V & = & \textbf{21.6 L} \\\end{array}\\\text{The volume of carbon dioxide is $\large \boxed{\textbf{21.6 L}}$}\)

Due to increased nuclear attraction, the periodic trend is that electron affinity rises from left to right over time.

Typically, electron affinities rise (become more negative) from top to bottom down a group and fall (become less negative) from left to right across a period.

Electronegativity, ionisation energy, electron affinity, atomic radius, melting temperature, and metallic nature are important periodic trends. Chemists can forecast an element's properties with great speed thanks to periodic trends, which are created by the periodic table's organisation.

Fluorine has the highest electronegativity, whereas Chlorine has the highest electron affinity due to the tremendous repulsion in Fluorine's closely packed 2p subshell (whereas chlorine is an atom with a larger atomic size).

An individual would take approximately 4 grams of aluminum hydroxide, 4 grams of magnesium hydroxide, and 0.4 grams of simethicone in a 24-hour period when following the recommended dose of Maalox.

The recommended dose of Maalox is two teaspoons four times a day. Each 5.0-ml portion of Maalox contains 400. mg of aluminum hydroxide, 400. mg of magnesium hydroxide, and 40. mg of simethicone. To calculate how many grams of each substance an individual would take in a 24-hour period, we need to multiply the dose by the amount of each substance in one dose.

First, let's convert teaspoons to milliliters. Since 1 teaspoon is approximately equal to 5.0 ml, two teaspoons would be equal to 10.0 ml.

Next, we calculate the total amount of each substance in a 24-hour period:

Aluminum hydroxide: 400 mg x 10 (doses per day) = 4000 mg = 4 grams
Magnesium hydroxide: 400 mg x 10 (doses per day) = 4000 mg = 4 grams
Simethicone: 40 mg x 10 (doses per day) = 400 mg = 0.4 grams

Therefore, an individual would take approximately 4 grams of aluminum hydroxide, 4 grams of magnesium hydroxide, and 0.4 grams of simethicone in a 24-hour period when following the recommended dose of Maalox.

The volume of 0.00703 mol of neon gas under the same temperature and pressure as 0.00901 mol of neon gas occupying 242 ml is 188 ml.

According to the Ideal Gas Law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

Assuming that the temperature and pressure are constant, we can set up a proportion to find the volume of 0.00703 mol of neon gas:

0.00901 mol neon / 242 ml = 0.00703 mol neon / x

Solving for x, we get:

x = (0.00703 mol neon * 242 ml) / 0.00901 mol neon

x = 188 ml

Therefore, the volume of 0.00703 mol of neon gas under the same conditions is 188 ml.

Answer:Open this pdf if has the answers

Explanation:

To determine the freezing point of the solution, we need to calculate the molality of the solution. Molality is defined as the number of moles of solute per kilogram of solvent.

Let's assume the initial concentration of the weak acid HA is C, and it ionizes to a small extent x. Therefore, the concentration of the ionized form, A-, can also be approximated as x.

The concentration of the undissociated weak acid HA can be approximated as (C - x), as only a small fraction x is ionized.

Given that the solution is 1.5% ionized, we can write the equation for ionization as follows:

0.015 = (x / C) * 100

Simplifying the equation, we have:

x = (0.015 / 100) * C

The molality of the solution can be calculated using the formula:

molality = moles of solute / mass of solvent in kg

Since the volume of the solution is not given, we can assume it to be 1 L for simplicity. Therefore, the mass of the solvent (water) is 1 kg.

The number of moles of the weak acid HA is (C - x) and for the ionized form A- is x.

molality = (C - x) / 1 kg

To express the molality in terms of concentration, we can substitute x using the equation derived earlier:

molality = [C - (0.015 / 100) * C] / 1 kg

Simplifying the equation:

molality = C * (1 - 0.015 / 100) / 1 kg

molality = C * 0.9985 / 1 kg

Now, using the freezing point depression equation:

ΔT = Kf * molality

where ΔT is the freezing point depression and Kf is the freezing point depression constant for water (1.86 °C/m).

Plugging in the values:

ΔT = 1.86 °C/m * (C * 0.9985 / 1 kg)

ΔT = 1.86 * C * 0.9985 °C

To find the freezing point, we set ΔT to 0.1000 m (since the concentration of the solution is 0.1000 m).

0.1000 = 1.86 * C * 0.9985

Solving for C:

C = 0.1000 / (1.86 * 0.9985)

C ≈ 0.0535 mol/L

Now, we can substitute this value of C into the equation for ΔT:

ΔT = 1.86 * 0.0535 * 0.9985 °C

ΔT ≈ 0.0997 °C

Since ΔT represents the freezing point depression, the freezing point of the solution is the freezing point of pure water (0 °C) minus the depression:

Freezing point = 0 °C - 0.0997 °C ≈ -0.0997 °C

Among the given answer choices, the closest option to -0.0997 °C is -0.0764 °C. Therefore, the correct answer is option a. -0.0764 °C.

The oxidation and reduction reactions in a redox reaction are known as redox half-reactions. The oxidation reaction is a half-reaction in which a substance loses electrons, while the reduction reaction is a half-reaction in which a substance gains electrons.

In this case,Oxidizing agent: H+ ions in aqueous HCl are the oxidizing agent. Reducing agent: Zinc metal is the reducing agent. Substances being oxidized: Zinc atoms in the zinc metal are oxidized to Zn2+ ions. Substances being reduced: H+ ions in aqueous hydrochloric acid are reduced to H2 gas.Explanation:Consider the following chemical reaction:Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)In this reaction, the oxidation state of zinc goes from zero in the solid state to +2 in the aqueous solution.

This means that zinc has lost electrons and has been oxidized. This implies that zinc is the reducing agent in this reaction. The oxidation state of H+ ions in aqueous hydrochloric acid is +1. When H+ ions in hydrochloric acid reduce to H2 gas, their oxidation state drops to zero. This implies that H+ ions are being oxidized and hence they are the oxidizing agent in this reaction. Therefore, the oxidizing agent is H+ ions, the reducing agent is zinc, the substance being oxidized is H+ ions in aqueous hydrochloric acid, and the substance being reduced is zinc metal.
