I suppose that would be a summary of a change which is not chemical. Perhaps it would be something like ice --> water
Magnesium + oxygen =magnesium oxide
Is may be written (aq), meaning aqueous, beside the chemical formula. Example =NaOH(aq) + Zn ---> Na2Zn(OH)4 + H2This equation is for "Sodium Zincate"
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
A banana is a very good non-example.
A banana is a non-example.
The antonym for "chemical equation" is "non-chemical equation" or simply "equation" if the context is clear that it is not related to chemistry.
An example of a balanced chemical equation is: NaOH + HCl = NaCl + H2O
In the equation 2x 5 11, the number 5 is an example of a non-variable.
For example melting of lead.
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) .
HNO3 + KOH -----> KNO3 + H2O
chemical equation
These subscripts are down the chemical symbol and at right. Example: O2
An example of a wrong function equation is f(x) = sqrt(x) for all non-negative x.
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.
