How does a catalyst influence a chemical reaction? o It speeds up or slows down a chemical reaction by direct participation.
O It reacts with products to increase the concentration of reactants.
O It decreases the amount of energy necessary for the reaction to proceed.
It increases the total amount of products formed.

decreases amount of energy necessary for reaction to proceed

Explanation:

they lower activation energies of the reactions they catalyse

it takes hundreds of years to become stable.

if you have another question lmk.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
