The image below shows models that represent the reactants and products of a chemical reaction.

Based on the image below, which of the following is true?


A. Mass could have either been gained or lost during this chemical reaction because atoms always change mass when they react.

B. Mass was lost in this chemical reaction because the atoms in the reactants are smaller than the atoms in the products.

C. Mass was conserved in this chemical reaction because the same atoms are present in both the products and the reactants.

D. Mass was gained in this chemical reaction because there are more atoms in the products than there were in the reactants.

The chemical reactions are all around us the metabolism of food in our body and how we get light from sun are all chemical reactions. Here Mass was conserved in this chemical reaction because the same atoms are present in both the products and the reactants. The correct option is C.

A chemical reaction is defined as one in which the bonds are broken within the reactant molecules and results in the formation of new bonds within the product molecules in order to form a new substance.

The rate of a chemical reaction is affected by several factors like pressure, temperature and the concentration of the reactants. In a chemical reaction, a chemical change must occur.

The substances which appear on the left hand side of the chemical reaction are called reactants whereas the products appear on the right hand side. Here same atoms are present in both reactants and products.

Thus the correct option is C.

Write an explanation of the relationship between genes, proteins, and traits for the Blue Lobster.

You may think of a lobster as red, but about 1 in every 2 million lobsters is blue! This blue color is the result of a mutation in the lobster’s genes. The mutation causes the lobster to make an extra amount of a protein called astaxanthin. This protein is usually important for the red color that you see when the lobster is cooked, but in excess amount, makes the lobster blue.
