Answer:
No
Explanation:
The Earth would not have seasons if there is no revolution because the temperatures would not change.
Answer:
20 mL OF 6 M HYDROCHLORIC ACID WILL BE NEEDED
Explanation:
M1 V1 = M2 V2
M1 = Molarity of sodium hydroxide = 3 M
V1 = volume of sodium hydroxide = 40 mL
M2 = Molarity of hydrochloric acid = 6 M
V2 = Volume of hydrochloric acid = unknown
Rearranging the equation, we have:
V2 = M1 V1 / M2
V2 = 3 * 40 mL / 6
V2 = 120 / 6
V2 = 20 mL
To precipitate the benzoic acid by 6 M of hydrochloric acid, 20 mL volume will be needed.
Answer:
1. Add N2O and
3. Remove N2
Explanation:
In equilibrium, there is a balance between the concentrations of the reactants and products. If more reactants are added, the equilibrium will shift to the right, favoring the forward reaction. This cause an increase in the concentration of the product and the equilibrium constant is unchanged.
Products can also be removed in order to increase the amount of products formed, forward reaction. This shifts the equilibrium to the right.
In the reaction 2N2O <-----> O2 + 2N2, adding N2O to the mixture favors the forward reaction and more products are formed, equilibrium shifts to the right.
Also, removing the product formed favors the forward reaction as more products will be formed in order to achieve equilibrium. The equilibrium therefore shifts to the right.
