There are 6 atoms of oxygen on the reactant side of the following equation: 2Fe2O3 + 3C → 4Fe + 3CO2. Details about atoms can be found below.
<h3>How to find number of atoms?</h3>
The number of atoms of an element in a balanced equation is the amount of that element involved in the reaction.
According to this question, Iron oxide reacts with carbon to produce iron and carbon dioxide as follows:
2Fe2O3 + 3C → 4Fe + 3CO2
In this reaction, 2 × 3 atoms = 6 atoms of oxygen are present on the reactant side of the equation.

A. Organic catalysts are called enzymes.
Explanation:
The true statement of all is that organic catalysts are called enzymes. For example, saliva in the mouth is made up of different enzymes which are secreted in the human body.
- Catalysts reduces the activation energy and makes reaction proceed very fast. They generally increase the rate of chemical reactions.
- Catalysts like temperature affects the rate of chemical reaction. Chemical reactions increases as temperature increases.
- Catalysts in the human body are very useful because they help chemical reactions in the body to proceed at a much faster rate.

Answer:
i think so
Ba(OH)2 + H2SO4 ------> BaSO4 + 2H2O
1) Moles of Ba(OH)2 = moles of H2SO4 = 0.025L x 2)0.02M = 5.0 x 10^-4M
Concn of Ba(OH)2 in g/L = 5.0 x 10^-4M x 171.33g/mol = 0.086g/mol
