<u>(1) equal to the number of electrons gained</u>
(2) equal to the number of protons gained
(3) less than the number of electrons gained
<span>(4) less than the number or protons gained</span>
Answer:
The answer is (3) 1676 kJ. The heats of reaction at 101.3 kPa and 298 K for reaction: 4Al(s) +3O2(g)= 2Al2O3(s) is -3351 kJ. So for one mole of aluminum oxide is 3351/2=1676 kJ.
Answer:
the amount of product and reactant remains constant because the rates of the foward and reverse reactions are equal
Explanation:
Answer:
the pressure decreases because there is a sudden lack of air. some times, cans will crush if the air is sucked out; this is because the pressure on the outside is greater than the inside
8moles of SO_2 need 11mol O_2
Moles of sO_2

So
Moles of O_2
We know
- 1mol at STP=22.4L
- 1.4mol=0.14(22.4)=3.13L O_2
