Opinion : I disagree recycling can help them, but it still will not clear the environment.
Answer:
2 only is a pretty accurate answer the others dont make sense to me.
Explanation:
The pressure increase does not affect the equilibrium shift reaction.
The answer is -60.57 = -60.6 KJ.
CaC2(s) + 2 H2O(l) ---> Ca(OH)2(s) +C2H2(g) H= -127.2 KJ
Hf C2H2 = 226.77
Hf Ca(OH)2 = -986.2
<span>Hf H2O = -285.83
Now,
</span><span>add them up. 226.77 - 986.2 + (2*285.83) = -187.77
</span><span>Add back the total enthalpy that is given in the question
-187.77+127.2 = -60.57 </span>
Answer:
In a chemical formula, the elements in a compound are represented by their chemical symbols, and the ratio of different elements is represented by subscripts.
