Explanation:
Since this is an equilibrium problem, we apply le chatelier principle. This principle states that whenever a system at equilibrium is disturbed due to change in several factors, it would move in a way to annul such change.
C2H4(g) + Cl2 ⇔ 2C2H4Cl2(g)
When the concentration of C2H4 is increased, there is more reactant sin the system. In order to annul this change, the equilibrium position will shift to the right favoring product formation.
When the concentration of C2H4Cl2 is increased, there is more product in the system. To annul this change, the equilibrium position will shift to the left, favoring reactant formation.
Number of moles = mass/ molar mass
= 45.6g / 88.90g/mol
= 0.512 moles
The answer is B
hope this helps!!! have a great day
In balancing reactions, it is important to remember that each of the side in the reaction should have the same number of elements. We do as follows:
<span>2SO2(g) + O2(g) -> 2SO3(g)
H2S(g) + 3/2O2(g) -> SO2(g) + H2O(g)
Hope this answers the question. Have a nice day.</span>
Joshua saw the rising batter form the cake in the oven.
He saw that because of the reaction of baking soda/powder with the liquid in the batter.
