To find moles from grams would be the amount of grams which in your case is 3.4 divided by the molar mass which is just adding ip Si, O2
Answer:
The answer to your question is below
Explanation:
See the attachment.
Synthesis ΔH
ΔH = 25 - (-30) = 25 + 30 = 55 kJ Endothermic reaction
Single reaction
ΔH = 30 - 65 = -35 KJ Exothermic reaction
Double reaction
ΔH = 60 - 10 = 50 kJ Endothermic reaction
