Question

Calcium reacts with oxygen to form calcium oxide. the chemical equation for this reaction is ca o2→cao. what is the reactant, or what are the reactants, in the equation? responses o2 uppercase o subscript 2 end subscript ca uppercase c lowercase a cao uppercase c lowercase a uppercase o ca o2

Answer 1

In the equation Ca + O2 → CaO, the reactants are calcium (Ca) and oxygen (O2) and the product is calcium oxide (CaO).

Step-by-step explanation:

The reactants in the chemical equation Ca + O2 → CaO are calcium (Ca) and oxygen (O2). During this chemical reaction, calcium reacts with oxygen to form calcium oxide (CaO), which is also known as quicklime or lime in industrial markets. Calcium oxide has various applications due to its reactivity and is particularly notable for its use in the production of calcium hydroxide through the reaction with water, illustrated by CaO (s) + H2O (l) → Ca(OH)2 (aq).
