Which describes an attribute of nonrenewable resources? exist in fixed amounts are unlimited can often be replaced in a short time are replaced faster than they are used

exist in fixed amounts

Explanation:

The only attribute that describes nonrenewable resources is the existence in fixed amounts.

Nonrenewable resources are limited in amount and depleted at a much faster rate than they are naturally replaced. Even when they are to be replaced, it cannot be done within a short period.

An example is crude oil which exists as natural deposits deep in the ground. The world's crude oil deposit is limited and cannot be replaced at a rate they are being used by man if at all it can be replaced.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
