Answer:

chemical change

Explanation:

turning methane plus oxygen into carbon dioxide and water is a chemical process because the substances change into completely new substances (co2 and water), it's no longer methane and oxygen. It's not a physical change because physical changes only affect appearance.

If this was a lab, possible evidences of a chemical change can be bubbling, heat, color change (occasionally)... etc.

chem isn't my best course but I hope this helps

Volume occupied 3.52x10^32 moluchles<br>of Mathane (CH4)<br>1) At STP

Naddika [18.5K]

Answer:

volume = 13097674418.528dm³

Explanation:

n = (3.52)*10^32/(6.02)*10^23)

n = (584717607.97)

n = volume /molar volume

molar volume at stp = 22.4dm³

volume= 584717607.97 x 22.4

volume = 13097674418.528dm³
