The empirical formula of a compound is determined to be N2O5. If the molar mass of the compound is 108 g/mol, determine the molecular formula of the compound.

The Empirical Formula Of A Compound Is Determined To Be N2O5. If The Molar Mass Of The Compound Is 108

Answers

Answer 1

Answer:

N2O5

Explanation:

Empirical formular is the simplest formular of a compound and shows the atoms present in simple rations.

Molecular formular on the other hand shows the exact number of atoms of element present in a compound.

To obtain molecular formular from empirical formular;

(Empirical formular)n = Molar mass

where n is a simple integer.

(N2O5)n = 108 g/mol

Molar mass of N2O5 = 108 g/mol

(108) n = 108

n = 108 / 108 = 1

Molecular formular = (Empirical formular)n

Molecular formular = (N2O5)*1 = N2O5

In this question, the empirical formular is the same as the molecular formular

What is the percent by mass if 110 g of baking soda is dissolved in 125 g of water to make 235 g of solution?

Answers

Answer: The percent by mass of baking soda in the solution is approximately 46.81%.

Explanation:

Percent by mass is calculated as the mass of solute (baking soda) divided by the mass of the solution (baking soda + water) and then multiplied by 100.

In this case:

Mass of baking soda (solute) = 110 g

Mass of water (solvent) = 125 g

Mass of solution = 110 g + 125 g = 235 g

Percent by mass = (mass of baking soda / mass of solution) x 100

Percent by mass = (110 g / 235 g) x 100 ≈ 46.81%

The percent by mass of baking soda in the solution is approximately 46.81%.

The standard enthalpy change for the given reaction is approximately 91.9 kJ mol⁻¹.

The heat produced during a chemical reaction under specific conditions is known as the standard enthalpy change, abbreviated as H° (zero delta H). Standard conditions often refer to all reactants and products in their standard states, which are their most stable forms at 298 K and 1 bar (or 1 atm) pressure.

Hess's law, which states that the total enthalpy change of a reaction is equal to the sum of the enthalpy changes of its component phases, is used to calculate the standard enthalpy change of the reaction.

The following reaction is given:

\(\rm 2 NaHCO_3(s)--- > Na_2CO_3(s)+ CO_2(g) + H_2O(l)\)

The relevant enthalpy changes of formation are:

ΔH°[NaHCO3(s)] = -950.8 kJ mol⁻¹

ΔH°[Na2CO3(s)] = -1130.7 kJ mol⁻¹

ΔH°[CO2(g)] = -393.5 kJ mol⁻¹

ΔH°[H2O(l)] = -285.8 kJ mol⁻¹

By using Hess's Law, the standard enthalpy change (ΔH°) for the reaction can be calculated as follows:

ΔH° = Σ (products) - Σ (reactants)

ΔH° = [ΔH°[\(\rm Na_2CO_3\)(s)] + ΔH°[\(\rm CO_2\)(g)] + ΔH°[H2O(l)]] - [2 × ΔH°[\(\rm NaHCO_3\)(s)]]

ΔH° = [-1130.7 kJ mol⁻¹ + (-393.5 kJ mol⁻¹) + (-285.8 kJ mol⁻¹)] - [2 × (-950.8 kJ mol⁻¹)]

ΔH° = [-1809.7 kJ mol⁻¹] - [-1901.6 kJ mol⁻¹]

ΔH° ≈ -1809.7 kJ mol⁻¹ + 1901.6 kJ mol⁻¹

ΔH° ≈ 91.9 kJ mol⁻¹

Hence, the standard enthalpy change for the given reaction is approximately 91.9 kJ mol⁻¹.

(D) HC2H3O2(aq)+NaOH(aq)→H2O(l)+Na+(aq)+C2H3O2−(aq)

Answers

The best representation of the species that react and the species produced in the reaction is;  HC₂H₃O₂(aq) + NaOH(aq) → H₂O(l) + Na⁺(aq) + C₂H₃O₂⁻(aq). Option D is correct.

In this titration reaction, a strong base (NaOH) is reacting with a weak acid (HC₂H₃O₂). The reaction between HC₂H₃O₂ and NaOH is a neutralization reaction, where the hydrogen ion (H⁺) from the acid combines with the hydroxide ion (OH⁻) from the base to form water (H₂O).

The sodium ion (Na⁺) and the acetate ion (C₂H₃O₂⁻) are spectator ions and are not involved in the actual reaction. They are present as ions in the solution but do not participate in the chemical change.

Therefore, the correct representation of the species that react and the species produced in the reaction is:

HC₂H₃O₂(aq) + NaOH(aq) → H₂O(l) + Na⁺(aq) + C₂H₃O₂⁻(aq).

Hence, D. is the correct option.

through electrolysis, a student collects 14.2 g of hydrogen gas and 112.8 g of oxygen gas. the reaction was allowed to proceed to completion. what was the mass of water initially present?

Answers

The mass of water initially present is 127 grams.

Mass cannot be created or destroyed, under the law of conservation of mass. As a result, the mass of reactants and products must be equal. Each element must have the same number of atoms on both the reactant and product sides. The balanced Chemical equations are :

2H₂O ⇒ 2H₂ +O₂

mass of hydrogen = 14.2 g

mass of oxygen = 112.8 g

Mass of products = Mass of hydrogen + mass of oxygen =  14.2+ 112.8 = 127 g grams

Thus mass or reactant = mass of water

Mass of reactants = mass of products = 127 g

Therefore the  mass of water initially present is 127 grams.

Answers

The conversion of the following Fahrenheit temperatures to the Celsius and Kelvin scales are as follows:

a. –459°F, an extremely low temperature = -273 °C; 0 K

b. –40.°F, the answer to a trivia question = -40°C; 233.15 K

c. 68°F, room temperature = 20°C; 293.15 K

d. 7 × 10⁷ °F, temperature required to initiate fusion reactions in the sun = 3.85 × 10⁷ °C; 3.85 × 10⁷ K

a. –459°F, an extremely low temperature

When we have to convert a given temperature from Fahrenheit to Celsius, we use the following formula:

F = 9/5 C + 32

Where C is the Celsius temperature and F is the Fahrenheit temperature.

(i) To convert -459°F to Celsius, we have to put the value in the above formula and get the Celsius temperature.

F = 9/5 C + 32

-459 = 9/5 C + 32

C = (-459 - 32) × 5/9 = -273 °C is the Celsius temperature of -459°F

(ii) To convert -459°F to Kelvin, we add 273 to the Celsius temperature.

K = C + 273

K = -273 + 273 = 0 K is the Kelvin temperature of -459°F.

b. –40.°F, the answer to a trivia question

(i) To convert -40°F to Celsius, we use the given formula.

F = 9/5 C + 32

-40 = 9/5 C + 32

C = (-40 - 32) × 5/9 = -40°C is the Celsius temperature of -40°F.

(ii) To convert -40°F to Kelvin, we first convert the Celsius temperature to Kelvin by adding 273.15.

K = C + 273.15

K = -40 + 273.15 = 233.15 K is the Kelvin temperature of -40°F.

c. 68°F, room temperature

(i) To convert 68°F to Celsius, we use the given formula.

F = 9/5 C + 32

68 = 9/5 C + 32

C = (68 - 32) × 5/9 = 20°C is the Celsius temperature of 68°F.

(ii) To convert 68°F to Kelvin, we first convert the Celsius temperature to Kelvin by adding 273.15.

K = C + 273.15

K = 20 + 273.15 = 293.15 K is the Kelvin temperature of 68°F.

d. 7 × 10⁷ °F, temperature required to initiate fusion reactions in the sun

(i) To convert 7 × 10⁷ °F to Celsius, we use the given formula.

F = 9/5 C + 32

7 × 10⁷ = 9/5 C + 32

C = (7 × 10⁷ - 32) × 5/9 = 3.85 × 10⁷ °C is the Celsius temperature of 7 × 10⁷ °F.

(ii) To convert 7 × 10⁷ °F to Kelvin, we first convert the Celsius temperature to Kelvin by adding 273.15.

K = C + 273.15

K = 3.85 × 10⁷ + 273.15 = 3.85 × 10⁷ K is the Kelvin temperature of 7 × 10⁷ °F.

what is the mass of 1.20 x 1024 molecules of sulfur dioxide, so2?

Answers

The mass of 1.20 x 1024 molecules of sulfur dioxide is 4.02 x 10^27 g.

First, find the molar mass of sulfur dioxide, SO2.

Molar mass of sulfur (S) = 32.07 g/mol, Molar mass of oxygen (O) = 15.999 g/mol, Molar mass of SO2 = (2 × 15.999 g/mol) + 32.07 g/mol = 64.066 g/mol.

Use the molar mass of SO2 to convert the given number of molecules to grams.

1 mole of SO2 = 64.066 g

1 mole of SO2 contains 6.022 x 10^23 molecules of SO2

Therefore, 1.20 x 1024 molecules of SO2 = (64.066 g/mol) × (1.20 x 1024/6.022 x 10^23 mol^-1) = 4.02 x 10^27 g

Calculate the number of atoms in 24.83g calcium phosphate.

Answers

Avogadro's Number:

Avogadro's number, which is equal to 6.02214076 x \(10^{23}\) , is the quantity of units in one mole of any material. Hence, 1 mole of calcium phosphate,\(Ca_{3} (PO_{4}) _{2}\)   will contain 6.02214076 x \(10^{23}\)   atoms.

The molar mass of calcium phosphate is 310.18 g/mol,

Then, number of moles in 24.83g of calcium phosphate = \(\frac{mass}{molar mass}\)

                                                                                              = \(\frac{24.83}{310.18}\)

                                                                                               = 0.08 mole

Then, 0.08 mole of \(Ca_{3} (PO_{4}) _{2}\)   will contain,

= 0.08 moles x 6.02214076 x \(10^{23}\)   atoms

=  0.4818 x \(10^{23}\)   atoms = 4.818 x  \(10^{22}\) atoms.

if a student reacts 4.40 ml of acetic acid with 3.35 ml of isopentyl alcohol and obtains 3.25 ml of isopentyl acetate as the product, what was the percent yield

Answers

The percent yield of isopentyl acetate is 71.23% when reacting 4.4 ml f acetic acid with 3.35 ml of isopentyl alcohol

Percentage yield calculation

Percentage yield can be defined as the ratio of the actual yield of a reaction to the theoretical yield of a reaction, multiplied by 100.

The percentage yield is calculated as follows:

Percentage yield = (actual yield/theoretical yield) × 100

Given data:

Volume of acetic acid used = 4.40 ml

Volume of isopentyl alcohol used = 3.35 ml

Volume of isopentyl acetate obtained = 3.25 ml

Density of acetic acid = 1.049 g/mL and its molar mass = 60.05 g/mol

Density of isopentyl alcohol = 0.809 g/mL and its molar mass = 88.15 g/mol

Density of isopentyl acetate = 0.876 g/mL and its molar mass = 130.19 g/mol

The balanced chemical equation for the reaction is:

C5H11OH + CH3COOH → CH3COOC5H11 + H2O

First, we need to determine which reactant is the limiting reactant. We can do this by calculating the number of moles of each reactant:

Number of moles of acetic acid = (volume in mL) x (density) / (molar mass)Number of moles of acetic acid = (4.40 mL) x (1.049 g/mL) / (60.05 g/mol) = 0.0767 molNumber of moles of isopentyl alcohol = (volume in mL) x (density) / (molar mass)Number of moles of isopentyl alcohol = (3.35 mL) x (0.809 g/mL) / (88.15 g/mol) = 0.0307 mol

The mole ratio of acetic acid to isopentyl alcohol in the reaction is 1:1, so the limiting reactant is isopentyl alcohol because there are fewer moles of it.

The theoretical yield of isopentyl acetate can be calculated from the number of moles of limiting reactant:

Number of moles of isopentyl acetate = (number of moles of limiting reactant) = 0.0307 mol

Now we can calculate the percent yield:

Percent yield = (actual yield / theoretical yield) x 100%

The actual yield is given as 3.25 mL of isopentyl acetate, but we need to convert this to moles:

Number of moles of isopentyl acetate = (volume in mL) x (density) / (molar mass)Number of moles of isopentyl acetate = (3.25 mL) x (0.876 g/mL) / (130.19 g/mol) = 0.022 mol

Percent yield = (0.022 mol / 0.0307 mol) x 100% = 71.23%

Therefore, the percent yield of isopentyl acetate is 71.23%.

CH₃OH: \(\frac{42 g}{32\frac{g}{mole}}\)=  1.3125 molesCHCl₃: \(\frac{35 g}{121.35\frac{g}{mole}}\)= 0.2884 molesC₃H₇OH: \(\frac{50 g}{60\frac{g}{mole}}\)=  0.8333 moles

So, the total moles of the solution can be calculated as:

Total moles = 1.3125 moles + 0.2884 moles + 0.8333 moles

Total moles = 2.4342 moles

Finally, the more fraction of each component can be calculated as follow:

CH₃OH: \(\frac{1.3125 moles}{2.4342 moles}\)= 0.54 CHCl₃: \(\frac{0.2884 moles}{2.4342 moles}\)= 0.118C₃H₇OH: \(\frac{0.8333 moles}{2.4342 moles}\)= 0.342

In summary, the mole fraction of each component in the solution is:

CH₃OH: 0.54 CHCl₃: 0.118C₃H₇OH: 0.342
