If the volume of a system decreases the pressure will increase, shifting in the direction that gives smaller number of moles of gas molecules.(only applies to gas)
Answer:
Explanation:
1 mole of methane = C + H4 = 12 + 4 = 16
32 grams of methane is 32/16 = 2 moles.
1 moles of methane contains 4 moles of hydrogen (CH4). Note the 4 in CH4
2 moles of methane = 8 moles of hydrogen.
H2O has 2 moles of hydrogen
Each mole of water contains 2 moles of hydrogen.
8 moles of hydrogen / 2 moles = 4 moles of water.
