Answer:
13.00 g
Explanation:
To solve this problem, you need to understand the law of conservation of mass. This law means that whatever amount you start out with is what you should have at the end. The amount may be in different forms, but that amount is still there.
If you produced 10.00 g of B and 3.00 g of A, you should have started out with 13.00 g of AB.
10.00 + 3.00 = 13.00
Answer: 2.796 grams
Explanation:
According to stoichiometry:
1 mole of 
reacts with 1 mole of 
0.012 moles of will react with=
of
Thus is the limiting reagent as it limits the formation of product. is the excess reagent as (0.018-0.012)=0.006 moles are left unused.
1 mole of produces 1 mole of 
0.012 moles of will produce= of
Mass of 
Thus 2.796 grams of are produced.
Answer:
b. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.
Explanation:
Kinetic - molecular theory -
According to this theory , gas is considered to be as a large number of very small particles , which moves randomly , and due to this randomness collisions occurs , as the particles collide with each other and the wall of the container .
During these collisions , there is no loss or gain of energy , there is only transfer of energy .
