If one starts with 0.020 g of Mg, 0.0008 moles of H2 would be made if the reaction is complete.
Going by the balanced equation of reaction in the image, 1 mole of Mg will produce 1 mole of H2 in a complete reaction.
If 0.020 g of Mg is started with:
mole of Mg = mass/molar mass
= 0.020/24.3
= 0.0008 moles
Since the mole of Mg to H2 is 1:1, thus, 0.0008 moles of H2 will also be made from the reaction.

I don't think so!!
Besides the fact that you're amazed at how cool the moon is.
Answer:
"Protecting the privacy of your employees is critical to the long term success of your business. Senior leadership, high-profile executives and their families, as well as other customer-facing employees are particularly vulnerable to targeting to bad actors when their personal information is exposed. Other potential sources of danger include disgruntled employees, ex-employees and even customers."
Hope this helps :)
The amount of heat required to purify the Al is 25.94 * 10^3 J
<h3>What is heat capacity?</h3>
The term heat capacity refers to the amount of heat required to raise the temperature of a substance by 1K. The aluminum was heated from 298 K to 933 K then it melted.
The total heat required is;
H = ncdT + nL
H = (1 * 24 * (933 - 298)) + (1 * 10.7 * 10^3)
H = 15.24 * 10^3 J + 10.7 * 10^3 J
H = 25.94 * 10^3 J
