Which is a balanced chemical equation?

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

What is a balanced chemical equation quizlet?

balanced equation. a chemical equation in which mass is conserved; each side of the equation has the same number of atoms of each element. combination reaction. a chemical change in which two or more substance react to form a single new substance; also called a synthesis reaction.

Which of the following is a balanced chemical equation Brainly?

“C7H16 + 11O2 —> 7CO2 + 8H2O”. Explanation: A balanced chemical equation is defined as a reaction where the type and number of atoms is equally distributed within the reactants and the products. In this case, C7H16 + 11O2 —> 7CO2 + 8H2O is an example of a balanced chemical equation.

How is a chemical reaction that absorbs energy in the form of heat described?

Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.

What is a balanced chemical equation Why should?

Why should chemical equations be balanced? Answer: According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side.

What is short chemical equation?

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. The first chemical equation was diagrammed by Jean Beguin in 1615.

What is a chemical equation class 8?

A chemical equation represents the changes that occur during a chemical reaction. It has the general form: Reactants → Products. All chemical equations must be balanced. This means that there must be the same number of each type of atom on both sides of the arrow.

What is importance of chemical equation?

Chemical equation gives information about the changes (State, chemical composition, heat energy) occurred in a chemical reaction. In order to write the chemical equation it is need to know the formulae of the elements or compounds which are involved in the chemical reaction.

How does chemical reaction affect your life?

By observing chemical reactions, we are able to understand and explain how the natural world works. Chemical reactions turn food into fuel for your body, make fireworks explode, cause food to change when it is cooked, make soap remove grime, and much more.
