What is the chemical law of equivalence?

According to the law of equivalence, the number of gram equivalents of each reactant and product in a reaction are equal.

How do you balance a chemical rea?

Identify and count the atoms of both the reactants and products in the following unbalanced reaction. Identify and count the atoms in both the reactants and products in the following reactions. To balance a reaction means to make the number of atoms the same on both the reactants and products side.

How do we use this law when balancing a chemical equation?

Balancing Chemical Equations

1. Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed.
2. Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation.

How do you use the law of equivalence?

According to the law of equivalence, whenever two substances react, the equivalents of one will be equal to the equivalents of other and the equivalents of any product will also be equal to that of the reactant. Let us suppose we have a reaction, A + B → C + D.

How do you find the equivalent of a substance?

To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid’s molar mass by the number of protons.

How do you find equivalents in chemistry?

Which of the following is correct according to equivalent concept?

Answer: 1. W1/W2=E1/E2 is correct according to equivalent concept.

What does equivalent mean in chemistry?

An equivalent (symbol: officially equiv; unofficially but often Eq) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. react with or supply one mole of electrons in a redox reaction.
