Answer:

K = 1.79x10⁻³³

Explanation:

Using Hess's law, it is possible to fin K of a reaction by the algebraic sum of another related reactions.

In the reactions:

1. N2(g)+O2(g) ⇌ 2NO(g), K1 = 4.10×10−31 2.

2. N2(g)+2H2(g) ⇌ N2H4(g), K2 = 7.40×10−26

3. 2H2O(g)⇌2H2(g)+O2(g), K3 = 1.06×10−10

The sum of 1/2 (1) + 1/2 (2) produce:

N2(g) + 1/2O2(g) + H2(g) ⇌ 1/2N2H4(g) + NO(g)

And K' = √4.1x10⁻³¹×√7.4x10⁻²⁶ = 1.74x10⁻²⁸

Now, this reaction + 1/2 (3):

N2(g) + H2O(g) ⇌ NO(g) + 1/2N2H4(g)

And K of reaction is:

1.74x10⁻²⁸×√1.06x10⁻¹⁰ = <em>1.79x10⁻³³</em>

Consider the following balanced reaction. How many grams of water are required to form 75.9 g of HNO3? Assume that there is exce
Iteru [2.4K]

Answer:

10.85 g of water

Explanation:

First we write the balanced chemical equation

3NO_{2} +H_{2}O -->2HNO_{3} +NO

Then we calculate the number of moles of nitric acid produced

n(HNO3) = \frac{mass}{molar mass} =\frac{75.9g}{63.02g/mol}=1.2044 mol

According to the balanced equation, water needed in moles is always half the number of moles of HNO3 produced. So since we will produce 1.2044 mol of HNO3, we will need 0.6022 mol of water. Now to calculate what mass that is:

mass(water)=number of moles*molar mass=0.6022mol*18.02g/mol=10.85g

Describe two situations that reduce the dissolved oxygen content of water?
Olin [163]
Hi sweetie, hope this helps!

The more salt that is dissolved in the water, the less oxygen will be dissolved in it.

The higher the temperature of the water, the less oxygen will be dissolved it in.


Goodluck!,

29.0g silver combine completely with 4.30g of sulfur to form a compound. what is the percent composition of this compound?
Deffense [45]

Answer:

Percentage of silver and sulphur in the compound  is 87.08% and 12.91%  respectively

Explanation:

Given:

Amount of silver = 29.0 g

Amount of sulphur= 4.30 g

To find:

Percent composition of the compound=?

Solution:

\text { percent of compound }=\frac{\text { amount of element }}{\text { Total Molecule Mass }} \times 100

Total Molecule mass = amount of silver + amount of sulphur

Total Molecule mass = 29+4.3  

Total Molecule mass = 33.3g

Percentage of silver:

\text { Percentage of silver }=\frac{\text { amount of silver }}{\text { Total Molecule Mass }} \times 100

=>\frac{29.0}{33.3}\times100

=>0.8708 \times100

=> 87.08%

Percentage of silver:

\text { Percentage of silver }=\frac{\text {amount of suplhur}}{\text { Total Molecule Mass }} \times 100

=>\frac{4.30}{33.3}\times 100

=>0.1291\times 100

=> 12.91%
