If a reaction releases 675,000 Joules, how many kcal does it release?

Chemistry

Mamont248 [21]3 years ago
5 0

Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.

Explanation:

According to the standard conversion,

1 Joule = 0.000239006 kcal

Therefore, 675,000 Joules will be converted into kcal as follows.

1 Joule = 0.000239006 kcal\\675,000 J = 675000 J \times \frac{0.000239006 kcal}{1 J}\\= 161.328872 kcal

Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.

horsena [70]

Answer:

The addition of sulfate ions shifts equilibrium to the left.

Explanation:

Hello!

In this case, according to the following ionization of strontium sulfate:

SrSO_3(s)\rightleftharpoons Sr^{2+}+SO_4^{2-}

It is evidenced that when sodium sulfate is added, sulfate, SO_4^{2+} is actually added in to the solution, which causes the equilibrium to shift leftwards according to the Le Ch athelier's principle. Thus, the answer in this case would be:

The addition of sulfate ions shifts equilibrium to the left.

Best regards!
