A sample of 10.5 g of nitrogen reacts with 20.2 g of hydrogen to produce ammonia.
3H2 (g) + N2 (g) → 2NH3 (g)
I need help answering these questions

Answers

Answer 1

The mass of NH₃ produced in the reaction of 10.5 g of nitrogen and 20.2 g

of hydrogen is 12.75 g

The balanced chemical equation is represented as follows:

3H₂ (g) + N₂ (g) → 2NH₃ (g)

Knowing the limiting reagent will assist us to ascertain the amount of Ammonia produced.

Therefore,

mass of H₂ = 20.2 g

molar mass = 2g/mol

moles = 20.2 / 2 = 10.1 moles

10.1 / 3 = 3.36666666667

mass of N₂ = 10.5 g

molar mass N₂ = 28 g /mol

moles = 10.5 / 28 = 0.375  moles

0.375 / 1 = 0.375

Therefore, nitrogen is the limiting reagent and it will determine the amount

of product formed.

28 g of N₂ gives 2(17) g of NH₃

10.5 g of N₂ will give ? of NH₃

cross multiply

mass of NH₃ produced = 10.5 × 34 / 28

mass of NH₃ produced = 357 / 28

mass of NH₃ produced = 12.75 g

After 200 million years, only 1/16 of the original amount of a particular radioactive waste will remain. The half-life of this radioactive waste is how many million years

Answers

Answer:

50 millions years

Explanation:

1 to 1/2 to 1/4 to 1/8 to 1/16

It takes 4 half lives to get to 1/16 of the original amount

200 million/4 = 50 millions years

The half-life of the radioactive waste is 50 million years.


To calculate the half-life of the radioactive waste, we use the formula below.

Formula:R/R' = [tex]2^{n/a}[/tex]............... Equation 1

Where:

R = Original amount of the radioactive wasteR' = Remaining amount of the radioactive waste after decayn = Total timea = Half-life of the radioactive waste.

Assuming: The original amount of the radioactive waste is y

From the question,

Given:

R = yR' = y/16n = 200 million years.

Substitute these values into equation 1

y/(y/16) = [tex]2^{200/a}[/tex]16 = [tex]2^{200/a}[/tex]

Solve for a

[tex]2^{200/a}[/tex] = 2⁴

Equating the base

200/a = 44a = 200a = 200/4a = 50 million years.

Hence, The half-life of the radioactive waste is 50 million years.

drinking water. After a quick review of the treatment processes that municipal water

goes through before it comes from the tap you will learn about the still-present

measurable contamination of drinking water due to anthropogenic (human-made)

detected in the drinking water supplies of American and European metropolitan cities.

The engineering design process can be used to design solutions for a real-world

problem (contaminated water) that could affect health.

Engineering Connection

The water that comes from our faucets has passed through a complex system designed

by many different types of engineers. Civil, chemical, electrical, environmental,

geotechnical, hydraulic, structural and architectural engineers all play roles in the

design, development and implementation of municipalities' drinking water supplies and

delivery systems. Hydraulic engineers design systems that safely filter the water at a

rate needed to supply a specific region and population. Chemical engineers precisely

determine the amounts and types of chemicals added to source water for coagulation

and decontamination to make the water safe to drink and not taste bad. Even so,

modern pharmaceutical and agricultural practices persist in contaminating our water

supplies.

What is the minimum amount of ammonium carbonate, in grams, that reacts to produce 1.0 mole of
ammonia?

Answers

Answer:

This is a simple stoichiometry problem using the ideal gas law.  

First, take the grams of ammonium carbonate and convert it to moles using its molar mass and dividing. 11.9 g/96.0932 g/mol= .12384 mol  

Now use a molar conversion using the balanced equation,  

1 mol (NH4)2CO3 ---> 4 mol gas formed (2 mol NH3 + 1 mol CO2 + 1 mol H2O) = .12384 x 4 = .49535 mol gas  

PV=nRT  

V=nRT/P= .49535mol (.08206 Lxatm/molxK) (296K)/ (1.03 atm)=11.682 L

Stoichiometry is used to determine the mass and the moles of the reactants and the products. 48 gms of ammonium carbonate is required to produce 1 mole of ammonia.

What is the stoichiometry coefficient?

Stoichiometry coefficients are the numbers before the molecules of the reactant or the product side of the reaction that presents the numerical quantity of the chemical species.

The balanced chemical reaction is given as:

(NH₄)2CO₃ → 2 NH₃ + CO₂ + H₂0

Hence, 2 moles of ammonia are produced from 1 mole of ammonium carbonate. So, 0.5 moles of ammonium carbonate will be needed to produce 1 mole of ammonia.

Mass of ammonium carbonate is calculated as:

Mass = moles × molar mass

= 0.5 mol × 96.09 g/mol

= 48 gm

Therefore, 48 gm of ammonium carbonate is required to produce 1 mole of ammonia.

A 100. mL reactor vessel is charged with 250. mg of P 4 and 4.21 atm of C l 2 at 298 K. The reaction goes to completion. How many moles of chlorine gas are initially in the vessel

Answers

There are 0.0172 moles of chlorine gas initially in the vessel.

Suppose we take a look and consider the reaction between P4 and Cl2, the balanced chemical equation between them can be expressed as:

[tex]\mathbf{P_4 + 6 Cl _2 \to 4 PCl_3}[/tex]

Given that:

mass of P₄ = 250 mg = 0.25gpressure of Cl₂ = 4.21 atmvolume of the reactor = 100 mL = 0.1 Ltemperature = 298 K

Using the Ideal gas equation, the number of moles of chlorine gas that were initially present in the vessel is:

PV = nRT

Making (n) the subject of the formula:

[tex]\mathbf{n = \dfrac{PV}{RT}}[/tex]

[tex]\mathbf{n = \dfrac{4.21 \ atm \times 0.1 \ L}{0.0821 \ atm.L/mol*K \times 298 \ K}}[/tex]

n = 0.0172 moles

Calculate the mass of 6.9 moles of nitrous acid (HNO2). Explain the process or show your work by including all values used to determine the answer.

Answers

Answer:

324.4 grams

Explanation:

47.013 g/mol is the molar mass of the nitrous acid.

Therefore with weight, nitrous acid is equal to 47.013 grams.

This value can be utilized to determine the mass of 6.9 moles within the same compound.

Since a single mole = 47.013 grams, we simply multiply:

6.9 x 47.013 = 324.4

The mass of the given nitrous acid contained in 6.9 moles is 324.3 g.

The molecular mass of the given nitrous acid is calculated as follows;

HNO₂ = (1) + (14) + (16 x 2)

M  = 47 g/mol

The mass of the given nitrous acid contained in 6.9 moles of the acid is calculated as follows;

m = nM

where;

n is the number of moles of the acidM is the molecular mass

m = 6.9 x 47

m = 324.3 g

Thus, the mass of the given nitrous acid contained in 6.9 moles is 324.3 g.

A sample of gas exhibits ideal behavior and occupies a volume of 350. mL at 25.0C and 1.00atm. How many moles of gas are present in the sample?

Answers

The number of mole of the gas present in the sample which occupies a volume of 350 mL at 25 °C and 1 atm is 0.0143 mole

From the question given above, the following data were obtained:

Volume (V) = 350 mL = 350 / 1000 = 0.35 L

Temperature (T) = 25 °C = 25 + 273 = 298 K

Pressure (P) = 1 atm

Gas constant (R) = 0.0821 atm.L/Kmol

Number of mole (n) =?

With the application of the ideal gas equation, the number of mole of the gas present in the sample can be obtained as follow:

PV = nRT

1 × 0.35 = n × 0.0821 × 298

0.35 = n × 24.4658

Divide both side by 24.4658

n = 0.35 / 24.4658

n = 0.0143 mole

Therefore, the number of mole of the gas present in the sample is 0.0143 mole

From the stoichiometry of the reaction, the mass of AgNO3 required is 340 Kg.

Number of moles of I2 produced in the third step = 254 × 10^3 g/254  g/mol = 1000 moles

In the first step, 1 mole of AgNO3 produces 1 mole of AgI

In the second step, 2 moles of AgI produces 1 mole of FeI2

In the third step, 2 moles of FeI2 produces 2 moles of I2

Hence;

In the third step;

1000 moles of I2 is produced by 1000 moles of FeI2

In the second step;

2 moles of AgI produces 1 mole of FeI2

x moles of AgI produces 1000 moles of FeI2

x = 2 moles × 1000 moles/ 1 mole

x = 2000 moles
