Answer: Option (e) is the correct answer.
Explanation:
Equilibrium is defined as the state of a chemical reaction in which the rate of forward reaction is equal to the rate of backward reaction.
The state of equilibrium is represented by a double sided arrow as "
" in a chemical equation.
For example, 
Therefore, we can conclude that when a reaction system is at equilibrium then the rates of the reaction in the forward and reverse directions are exactly equal.
N2 + 3 H2 >> 2 NH3
moles NH3 = 11.50 g /17.0307 g/mol=0.6753
the ratio between H2 and NH3 is 3 : 2
moles H2 needed = 0.6753 x 3/2 =1.013
mass H2 = 1.013 mol x 2.106 g/mol=2.042 g
Answer:
I think it was Hillary Clinton.
Explanation:
46 gram of ethanol ≡ 1 mole of ethanol
1 gram of ethanol ≡ 1/46 mole of ethanol
10 gram of ethanol ≡ 1*10/46 mole of ethanol
=0.217 mole of ethanol
Answer:
When two forces are the same strength but act in opposite direction, they are called balanced forces. Again, tug-of-war is a perfect example. If the people on each side of the rope are pulling with the same strength, but in the opposite direction, the forces are balanced. The result is no motion.
