Answer:
<h2>Metamorphic</h2>
Explanation:
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

The moles of O2 that are needed to react completely with 35.0 mol C2H2 is 87.5 moles of O2
<u><em>Explanation</em></u>
Write a balanced chemical equation for reaction of between C2H2 and O2
2 C2H2 + 5O2 → 4 CO2 + 2 H2O
if 35.0 moles C2H2 reacted then use the o mole ratio to determine the moles of C2H2
The mole ratio of C2H2 :O2 = 2:5 therefore the moles of O2
= 35 moles x5/2 = 87.5 moles of O2
