Which chemical equation is unbalanced?
C + O2 CO2
Sr + O2 2SrO
6H2 + 3O2 6H2O
H2 + H2 + O2 H2O +
Answers
Answer:Sr + O2 2SrO
Answer:
Sr + O2 ->2SrO is unbalanced
Explanation:
Unbalanced equation:
In an equation that is out of balance, the number of each type of atom on the reactant and product sides are not equal.
Example: The formation of water when hydrogen and oxygen react.
To equalise them, we must change the atom counts of some substances such that there are an equal number of each kind of atom on both sides.
the following will be the balanced equation:
A balanced equation is one in which the number of each element's atom on the reactants side equals the number of each element's atom on the product side.
The reactants and products of a chemical reaction are represented symbolically in a chemical equation by the appropriate chemical formulas.
A chemical equation that illustrates how hydrogen and oxygen react to create water is 2H2 + O2 2H2O.
The portion of the chemical equation on the reactant side is to the left of the symbol "," and the portion on the product side is to the right of the arrow symbol.
