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

What is the specific latent heat of fusion of ice if it takes 863 kJ to convert 4.6 kg of ice into water at 0 C?
charle [14.2K]

Answer:

The correct answer is 187.7 J/Jg.

Explanation:

The formula for finding the specific heat of fusion is,  

Specific heat of fusion = Q/m

Here Q is the heat energy added, signified in kJ, and m is the mass of the object in kg.  

Based on the given information, the heat energy added or Q is 869 kJ and the mass of the ice is 4.6 Kg

Now putting the values in the formula we get,  

Specific heat of fusion = Q/m

Specific heat of fusion = 863 kJ / 4.6 Kg = 187.7 J/Kg

Relate dark matter to the development of the universe after the Big Bang. In 3-5 sentences, speculate on how the development of
Alenkinab [10]

Answer:

Dark matter makes up 85% of the mass of the universe. Dark matter is not directly observable because it doesn't interact with any electromagnetic wave. In the development of the universe, without dark matter, the universe will not function, move or rotate as it does now (this speculation led to the quest to find the anomaly of mass and energy in the known universe, eventually leading to the idealization of dark matter) and will not have enough gravitational force to hold it together.  After the big bang,<em> the presence of dark matter and energy ensured that the newly formed universe didn't just float away, rather, it provided enough gravitational force to hold the universe while still allowing it to expand sufficiently</em>.

The development of the universe would have been different without the universe in the sense that the young universe won't have enough mass to hold it together, and the universe would have simply floated apart. The behavior of the universe would have been different from what we observe now, and some physical laws that applies now will not apply to the universe.

Reduction Is Gain of electrons 

If something goes from + to - then it has gained electrons 
If something goes from neutral to - it has gained electrons 
If it goes from - to + is loses electrons 
If it goes from neutral to + it loses electrons 

If something is oxidised, it is a reducing agent 
If something is reduced, it is an oxidising agent
