<u>Answer:</u> 18 moles of H_2O will be produced.

<u>Explanation:</u>

We are given:

Moles of ammonia = 12 moles

The given chemical equation follows:

4NH_3+5O_2\rightarrow 4NO+6H_2O

By the stoichiometry of the reaction:

4 moles of ammonia produces 6 moles of water

So, 12 moles of ammonia will produce = \frac{6}{4}\times 12=18mol of water

Hence, 18 moles of H_2O will be produced.

How many moles of gas occupy 98 l at a pressure of 2.8 atmosphere and a temperature of 292
lara [203]

Answer:

n = 11.45 mol

Explanation:

Given data:

Number of moles = ?

Volume of gas = 98 L

Pressure = 2.8 atm

temperature = 292 K

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

2.8 atm × 98 L = n × 0.0821 atm.L/ mol.K   × 292 K

274.4 atm.L = n ×  23.97atm.L/ mol

n = 274.4 atm.L /23.97atm.L/ mol

n = 11.45 mol

atch the following aqueous solutions with the appropriate letter from the column on the right. fill in the blank 1 A 1. 0.20 m N
Firdavs [7]

Answer:

Highest boiling point - 0.43 m Urea

Second highest boiling point - 0.20 m NiSO4

Third highest boiling point - 0.19 m NH4I

Lowest boiling point - 0.17 m NH4NO3

Explanation:

We know that;

ΔT = kb m i

Where;

ΔT = boiling point elevation

kb = boiling point constant

m = molality of the solution

i = Van't Hoff factor

For NiSO4 , NH4I  and NH4NO3 , the Van't Hoff factor, i = 2

But for Urea, the Van't Hoff factor, i = 1

We also have to consider both the values of the molality and Van't Hoff factor , knowing that a higher molality and a higher Van't Hoff factor leads to a higher ΔT and consequently a higher boiling point.

This facts above account for the arrangement of substances shown in the answer.
