Chemical Equations and formulas

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products along with their quantities.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction that undergo change.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction.

Front

What does the law of conservation of mass state?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, ensuring the law of conservation of mass is satisfied.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure the same number of each type of atom appears on both sides.

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula in an equation to indicate how many molecules or moles of that substance are involved.

Front

What is a subscript in a chemical formula?

Back

A subscript is a small number written after an element symbol in a chemical formula that indicates the number of atoms of that element in a molecule.

Front

What is a skeleton equation?

Back

A skeleton equation is a chemical equation that shows the reactants and products but not their coefficients, indicating the types of substances involved.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.
