Calcium Hydroxide (Ca(OH)2) reacts with the Carbon Dioxide (CO2) present in the Air to form Calcium Carbonate (CaCO3) and Water (H2O).
The equation looks something like this -->
Ca(OH)2 + CO2 = CaCO3 + H2O
Answer:

Explanation:
Hello there!
In this case, according to the given chemical reaction, it is possible for us to calculate the produced grams of nitrogen monoxide by starting with 25.0 g of nitrogen via their 1:2 mole ratio and the molar masses of 30.1 g/mol and 28.02 g/mol, respectively and by some stoichiometry:

Best regards!
Benzene and oil are related to organic chemistry branch.
Organic chemistry mostly deals with hydrocarbons (benzene is made from hydrocarbons)
Therefore, the chemist that uses benzene to make a new type of plastic is an organic chemist.
The answer is it breaks down food into energy
