Fibers that enter and leave the sympathetic chain without synapsing form structures called
mg + 2hcl → mgcl2 + h2
1 mol mg reacts with 2 mol hcl
0.50 mol mg will react with 1.0 mol hcl
molar mass hcl = 36.45g/mol
mass of hcl reacted = 36.45g
i hope this
answer: option (c) is the correct answer.
catalyst are the substances which in increasing the rate of a chemical reaction without itself getting consumed.
a catalyst changes the path of a reaction by lowering the activation energy level so that molecules with low energy can easily participate in the reaction and thus, formation of products become fast.
thus, we can conclude that out of the given options, a catalyst increase the speed of a reaction as the catalyst makes it easier for the activated complex to form, lowering the activation energy.
