Explanation:
calculate the molar mass for each of the following compounds 7. PbSO
8. Ca(OH)2
9. Na3PO4
10. (NH4)2CO3
11. C6H12O6
12. Fe3(PO4)2
13. (NH4)2S
14. Zn(C2H3O2)2
The answer would be 150 half of 200 and 100 is 150
Answer:

Explanation:
When it freezes, it will be a solid. The molecules will barely move, not as much as in the other answer choices.
Answer:
a) Sm
Explanation:
Hello,
This substantiation could be done by knowing how to compute the released energy for 1 mol the oxide. Thus, for Sm, the computation turns out into:
The sign just indicates that the heat is released due to the chemical reaction and it matches with the indicated heat in the statement.
Best regards.
