Answer:
B - To increase the rate of the reaction
Explanation:
Catalysts speed up the reaction without being reactants or products, so aren't used up in the reaction.
Answer:
Are less reactive
Explanation:
Alkaline-earth metals are to the right of alkali metals.
Since they both have the same momentum, the object with the larger mass has a small velocity. (Remember that mass and velocity are inversely proportional with
p=mv.) Therefore, the smaller object will have the larger KE. (KE = 1/2 ^2)
Essentially the term binary, meaning each different thing has two components. Binary ionic compounds have two ionic compounds, binary molecular compounds have two molecular compounds, and binary acids have two acids.
