how many moles of methane are produced when 25.1 moles of carbon dioxide gas react with excess hydrogen
Dafna11 [192]
The chemical equation for this reaction is this:
CO2 + 4H2 = CH4 + 2H2O
 from the equation, the mole ration of CO2 to CH4 is ratio 1:1
and CH4 = 25.1
The mole ratio of H2 to H2O is 4:2
therefore, mole of H2 = 19.1* 4/2 = 38.2
The moles of methane produced is 38.2 moles

How does an enzyme’s active site relate to its substrate?
Fofino [41]

Answer:

The enzyme's active site must be the mold shape of the substrate.

Explanation:

An enzyme and a substrate bind together in order to work. If the shapes of the 2 are different, they will not be able to bond together. If the shapes of the 2 fit glove-in-hand, then they will be able to bond together.

Balance the following equation. Then determine the mole ratio of Ca(OH)2:Al(OH)3.
DENIUS [597]
Balanced equation:

Al2(SO4)3 +3 Ca(OH)2 ---> 2Al(OH)3 + 3CaSO4?

Check:
Left side: Al:2; [SO4]: 3; Ca: 3; [OH] 3*2 = 6

Rigth side: Al: 2; [OH]: 2*3 = 6; Ca:3; [SO4]: 3

Mole ratio of Ca(OH)2 : Al (OH)3

3 moles of Ca(OH)2: 2moles of Al(OH)3 = 3:2

Answer: Option B.
