What is the relationship between the amounts of chemical reactants and products?
Stoichiometry is exactly that. It is the quantitative relation between the number of moles (and therefore mass) of various products and reactants in a chemical reaction. Chemical reactions must be balanced, or in other words, must have the same number of various atoms in the products as in the reactants.
What is a reactant and product in a chemical reaction?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
How did you identify the reactants and products?
Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.
How do reactants and products compare in a chemical reaction?
A: Bonds break in the reactants, and new bonds form in the products. The reactants and products in a chemical reaction contain the same atoms, but they are rearranged during the reaction. As a result, the atoms end up in different combinations in the products. This makes the products new substances that are chemically different from the reactants.
What are the examples of reactants and products?
The reactants are less stable in the reaction, whereas products are generally more stable than the reactants in the chemical reaction. In the example of the candle burn, the reactants are the fuel (the candlewick and wax) and oxygen (present in air); on the contrary, the products in this example are carbon dioxide gas and water vapors.
What are the reactants and products of a reactant?
Reactants are substances that start a chemical reaction. Products are substances that are produced in the reaction. When a candle burns, the reactants are fuel (the candlewick and wax) and oxygen (in the air). The products are carbon dioxide gas and water vapor.
In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can’t change one element into another in a chemical reaction — that happens in nuclear reactions. Instead, you create a new substance with chemical reactions.
