The question is incomplete, here is the complete question:

Consider the reaction  4NH_3(g)+7O_2(g)\rightarrow 2N_2O_4(g)+6H_2O(g)

Initially, [NH_3(g)]=[O_2(g)] = 3.60 M; at equilibrium [N_2O_4(g)]=0.60M  . Calculate  the equilibrium concentration for NH_3

<u>Answer:</u> The equilibrium concentration of ammonia is 2.8 M

<u>Explanation:</u>

We are given:

Initial concentration of [NH_3(g)] = 3.60 M

Initial concentration of [O_2(g)] = 3.60 M

For the given chemical equation:

                     4NH_3(g)+7O_2(g)\rightarrow 2N_2O_4(g)+6H_2O(g)

Initial:               3.60        3.60            

At eqllm:      3.60-4x     3.60-7x           2x             6x

We are given:

Equilibrium concentration of [N_2O_4(g)] = 0.60 M

Evaluating the value of 'x'

\Rightarrow 2x=0.60\\\\\Rightarrow x=\frac{0.60}{2}=0.2

So, equilibrium concentration of NH_3=(3.60-4x)=(3.60-(4\times 0.2))=2.8M

Hence, the equilibrium concentration of ammonia is 2.8 M

Research how different fossil fuels compare in terms of the amount of carbon dioxide released per kWh of energy. How much carbon
pshichka [43]

Answer:

About 19.64 pounds of carbon dioxide are produced from burning a gallon of gasoline. On the other hand, 22.38 pounds of carbon dioxide are produced from burning a gallon of diesel. So, different fossil fuels will give different amounts of carbon dioxide to be released.

Briefly describe how the pH of a colourless solution could be measured using a universal indicator​
Firdavs [7]

Answer:

Universal indicator can show us how strongly acidic or alkaline a solution is, not just that the solution is acidic or alkaline. This is measured using the pH scale , which runs from pH 0 to pH 14.
