Plants manufacture molecules of glucose and use the glucose as a source of energy. [2] What percentage (%) does a plant use for itself?

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

d.) circle motion requires a force to give it a centripetal acceleration.

just did the assignment and the answer was #1 +2 n

the correct answer is:

a. formation of precipitation
