D = m/v
<span>D = 8g / 25 cm^3 x 1000,000 cm^3/1000g </span>
<span>D = 320 kg/ m^3 or 0.32g/cm^3

The least reactive out of those options is helium. Alkali metals are very reactive while noble gases are stable, and helium is a noble gas.
Answer:
Chemical equation:
Sr + S → SrS
Explanation:
Mg react with sulfur and form magnesium sulfate.
Chemical equation:
Mg + S → MgS
The oxidation state of magnesium is +2 it loses its two valance electrons while sulfur gain two electrons to complete the octet. That's why one atom of magnesium combine with one atom sulfur.
Chemical equation:
Sr + S → SrS
The oxidation state of strontium is +2 it loses its two valance electrons while sulfur gain two electrons to complete the octet. That's why one atom of strontium combine with one atom sulfur.
You are correct! this molecule is an ether, specifically diethyl ether.
OOH! I know photosynthesis and I have been doing it in school. So the Glucose and oxygen combine to help make the photosynthesis AND it is so important to not forget about Carbon Dioxide and all the features for that because a plant needs carbon dioxide while we need oxygen and plants give out oxygen so that humans can have it and we breathe out carbon dioxide so that plants can have it. We pretty much just help each other out. I plants weren't there than humans wouldn't be there. Hope this helps!
