The substances to the left of the arrow in a chemical equation are called?
The substances to the left are called Reactants, and the rights are Products . For example=H2 + Cl2 -----> 2HClHere, Hydrogen (reactant) gets combined with Chlorine (reactant) to form Hydrogen Chloride(product). The number 2 is used to balance the equation
An expression in which symbols and formulae represent a chemical reaction?
A chemical equation is an expression in which symbols and formulae represent a chemical reaction. It shows the reactants on the left side and the products on the right side, with coefficients to balance the number of atoms on each side.
What is a balanced chemical equation why should the chemical equation be balanced?
A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example: 2H20 --> 2H2 + O2 This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction). Technically the equation wouldn't work in real life if it weren't correctly balanced.
Is this equation balanced CaO HCL CaCl2 H2o Yes thank you What I need to know is the number of atoms in the reactants of the chemical equation?
The equation given is not balanced. To determine the number of atoms in the reactants, you need to balance the equation first. Once balanced, you can count the total number of atoms on each side of the equation.
How are word equations organized?
-The left side of the equation list all the reactants -The right side of the equation list all the products -An arrow points from the reactants to the products. It shows that something is produced during the reaction. All the reactants and all the products in a word equation are separated by a plus sign (+) reactant 1+reactant 2 ---> product 1 product 2

What are chemicals on the left side of the chemical equations?
In a chemical equation left hand side elements regarded as a Reactants , while right hand side is regarded as a products.
What is a balancing equations of chemical reactions?
coefficients
What tells you how many atoms or molecules of a reactant or a product take part in a reaction?
The coefficients in front of the reactants and products tell you how many atoms or molecules take part in a reaction. For example, the chemical equation 2 H2 plus O2 produces 2 H2O means that two hydrogen atoms react with one oxygen atom to produce two water molecules.
In the equation 2 H2 plus O2 --- 2 H2O what substances are the reactants?
The reactants in this equation are hydrogen gas (H2) and oxygen gas (O2).
How do you balance the chemical equation CO2 C--CO?
the chemical equation CO2 C--CO.it is balANCEd by :there are 2 carbons on reactants and 2 atoms of oxygen by putting 2 as coeffecient on product side,equationis balanced.CO2 + C --------> 2CO
What are the parts of a balanced chemical equation?
A balanced chemical equation must observe the law of conservation. There must always be the same number of the atom within the reactants and within the products. For example, in the reaction between NaOH and HCl: NaOH + HCl --> NaCl + H2O On both sides of the equation, I have 2 hydrogen atoms, 1 chlorine atom and 1 sodium atom.

What is the chemical equation for Ba2 and N3?
You're expressing those two reactants as ions. The chemical equation for the reaction between barium and nitrogen is: 3Ba + N2 --> Ba3N2. Or, if you like, the net ionic equation for the formation of the insoluble precipitate barium nitride is: 3Ba+2 + 2N-3 --> Ba3N2.
