What is the balanced chemical equation of the reaction of mixing sodium dichromate and nitric acid?
Sodium dichromate has the chemical formula of Na2Cr2O7. The reaction with HNO3 is balanced as 2 HNO3 + Na2Cr2O7 = H2Cr2O7 + 2 NaNO3.
What information are conveyed by a balanced chemical reaction why is it necessary to balanced a chemical equation?
A chemical reaction is always balanced, because chemical reactions follow the laws of conservation of mass and conservation of matter. A chemical equation for the reaction is balanced if and only if the same total numbers of each kind of atomic symbol appear on both the left and right sides of the equation.
What is the balanced chemical equation for the reaction of solid magnesium metal and barium chloride?
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.
How a balanced chemical equation really illustrate that mass is never lost or gained in a chemical reaction?
What information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction?
An equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are not the same for both the reactants and the products. In other words, the mass and the charge are not balanced on both sides of the reaction. This is also called as a unbalanced equation.
