O2(g)+2H2O(1)+4e---->4OH-(aq)
Sulfuric acid can be mixed with water but doesn't react.
Hydrochloric acid doesn't react with water; they form a solution.
Chromium don't react with water.
They do not react.
Sodium chloride is dissolved in water but doesn't react.
This depends on the other reactants !
Sodium fluoride dissolves in water but does not chemically react with water.
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.
They will NOT react, so no chemical equation. (Mixing is NOT chemical, besides these two won't mix homogeneously!
The balanced chemical equation is: MgO + H2O → Mg(OH)2 The product formed in this reaction is magnesium hydroxide.
water and the sodium salt
The answer is Be(OH)2
