What do you mean by a balanced chemical equation?
Balanced chemical equation: A chemical equation in which the number of each type of atom is equal on the two sides of the equation. Subscripts: Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element.
What are the types of chemical reactions?
Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.
Why do we balance chemical equations?
Remember, chemical reactions follow the law of conservation of mass. Chemical equations show this conservation, or equality, in terms of atoms. The same number of atoms of each element must appear on both sides of a chemical equation.
What does a balanced equation look like?
A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. In the products side, there are 1 nitrogen (N) atoms and 3 hydrogen (H) atoms. The number of the atoms is not balanced on both sides.
What happens if a chemical equation is not balanced?
Chemical reactions must be balanced, or in other words, must have the same number of various atoms in the products as in the reactants. If a chemical reaction is not balanced, no information about the relationship between products and reactants can be derived.
What is the balanced equation for Na cl2 nacl?
