<u>Answer:</u> 18 moles of 
will be produced.
<u>Explanation:</u>
We are given:
Moles of ammonia = 12 moles
The given chemical equation follows:
By the stoichiometry of the reaction:
4 moles of ammonia produces 6 moles of water
So, 12 moles of ammonia will produce = 
of water
Hence, 18 moles of will be produced.
Answer: A hypothesis is generally based upon either someone else's observation or on previous studies.
Explanation: They just keep testing it to make sure it's <em>always </em>true.
D. there would be a proportional increase in pressure to temperature
Same, I cannot answer the question. Try asking a high school student
The common substance among the product(s) of the first equation and among the reactant(s) in the second equation is H2O(g). We can eliminate that as an intermediate. The overall chemical equation will thus be:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(l),
which is the first answer choice.
In essence, all you’re doing here is swapping water vapor for liquid water.
