HNO3 + KOH -----> KNO3 + H2O
An example of a balanced chemical equation is: NaOH + HCl = NaCl + H2O
Br- is chemical symbol for a bromide anion. It is not an 'equation', it can be a part of a chemical equation, like in this precipitation reaction (example) Ag+(aq) + Br-(aq) --> AgBr(s) .
chemical equation
These subscripts are down the chemical symbol and at right. Example: O2
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.
The hydroxide ion is represented in a chemical equation as OH-. For example, in the chemical formula for sodium hydroxide, NaOH, the hydroxide ion is written as OH-.
A chemical equation is a shorthand description of a chemical reaction.
For example a neutralization reaction:HCl + NaOH = NaCl + H2O
A chemical reaction can be represented by a chemical equation.
A chemical formula is the way a particular chemical (element or compound) is represented using the letters given in the Periodic Table. For example, the chemical formula of oxygen is O2 and the chemical formula of caron dioxide is CO2A word equation describes a chemical reactionusing the names of chemicals only. For instance, the word equation for respiration is:glucose + oxygen => carbon dioxide + waterA formula equation also describes a chemical reaction, but uses chemical formulae instead of names and is balanced. An example of this would be methane burning in oxygen:CH4 + 2O2 => CO2 + 2H2O
The combustion of a nonmetal, such as sulfur, involves the reaction of the nonmetal with oxygen to form its oxide. For example, the combustion of sulfur can be represented by the chemical equation: S + O2 → SO2.
I suppose that would be a summary of a change which is not chemical. Perhaps it would be something like ice --> water
