Answer:
C. A reaction that absorbs heat
Explanation:
I do not know Latin, but roughly speaking 'Endo' means inside, and 'thermic' means heat.
From the equation:
4mol Li react with 1 mol O2
Molar mass Li = 7g/mol
mol in 84g Li = 84/7 = 12 mol Li
From the equation - 12 mol Li will react with 3 mol O2
At STP 1 mol O2 has volume = 22.4L
<span>
At STP 3 mol O2 has volume = 3*22.4 = 67.2L O2 gas will react. </span>
Ionic bond<span>, also </span>called<span> electrovalent </span>bond<span> , type of linkage </span>formed<span> from the electrostatic </span>attraction between oppositely charged ions<span> in a chemical compound.

In my opinion the answer is identical
Granite is stronger, and it doesn't grow mold in the rain. It also looks better than marble and is easier to carve.
