To solve a problem, sometimes people resort to trial and error. If they want a guaranteed solution, they may follow a(n) , which is a step-by-step procedure.

Options:

A. prototype.

B. heuristic.

C. algorithm.

D. confirmation bias.

C. Algorithm.

Explanation: Algorithm is a procedure of solving a problem by following a series of sequence that will help to solve the problems. Algorithm is applied both in the Field of Mathematics and Computer science.

Algorithm is the procedure adopted in search engines, algorithm also helps to solve recurring problems, it is a step by step approach, where each step is well thought out and has a defined pattern and approach.

A chemical  reaction is classified as exothermic or endothermic based on the direction of heat flow during the reaction

The correct option for what must occur for a reaction to be classified as an exothermic reaction is option C

C) Energy is released in the form of heat

The reasons the above value is correct are;

An exothermic reaction is one in which energy in the form of light, heat or other forms because the sum of the energy in the product is less than the sum of energy contained in the reactants

Therefore, for a chemical reaction to be specifically classified as an endothermic reaction, instead of an exothermic reaction, is energy, in the form of heat (or light) must be released

The correct option is option C
