Question
A chemical formula found on the arrow between the reactants and products in a chemical equation indicates the presence of a ____________.
- Catalyst
- Additional reactant
- Secondary product
- Hazardous by product
Hint:
A chemical equation shows the starting compound also known as reactant on the left hand side of the reaction and the final compound also known as the products on the right hand side of the reaction.
A catalyst is a chemical that can be included in a reaction to speed up the process without being consumed.
The correct answer is: Catalyst
A chemical formula found on the arrow between the reactants and products in a chemical equation indicates the presence of a Catalyst.
- The chemical formulae of the reactants (on the left) and products make up a chemical equation (on the right).
- A sign that looks like an arrow (read as "yields" when spoken aloud) separates the two and this indicates the presence of a catalyst.
- A plus sign separates the chemical formulas of each particular ingredient from those of other substances.
- Typically, catalysts shorten the activation energy of a process or alter its mechanism.
