Hey there !
<span>Balanced equation:
1 MgS +1 Na2O = 1 Na2S + 1 MgO
</span>
MgS = 1
Na2O = 1
Na2S = 1
MgO = 1
Answer D
Answer: $$3.60 * 10^(21)$$
Explanation: Let's try to create a conversion factor that will take us directly from the number of grams of calcium oxide
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
