<span>2 CH3OH + 3 O2 = 2 CO2 + 4 H2O
2 moles CH3OH ---------------- 3 moles O2
1.33 moles CH3OH ----------- ( moles O2)
moles O2 = 1.33 x 3 / 2
moles O2 = 3.99 / 2
= 1.995 moles of O2</span>
Answer:
represents the additional driving force required to overcome barriers such as the large activation energy for the formation of a gas at a metal surface.
Answer:
moles
Explanation:
We are given:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains
number of particles.
We know that:
Charge on 1 electron =
Charge on 1 mole of electrons =
The metal being plated has a +4 charge, thus the equation will be:

of electricity deposits = 1 mole of metal
Thus 861.8 C of electricity deposits =
moles of metal
Thus
moles of metal should be plated
Cr2O72- + 6CH3OH + 8H+ --- > 6CH2O + 2Cr3+ + 7H2O
Answer:
The energy absorbed in the first move is greater than the energy released in the second move.
Explanation:
When the electron goes up levels it absorbs energy to enter that higher energy state. When it goes down, it releases energy but just not as much because 1-4 is more than 4-2.
