Answer: gamma rays are high energy and may cause damage to healthy cells.
Explanation: I took the test!!
The reactant side of the given chemical equation C2H5OH + 3O2 → 2CO2 + 3H2O contains six hydrogen atoms.
The chemical equation in question is C2H5OH + 3O2 → 2CO2 + 3H2O. This refers to the reaction of ethanol (C2H5OH) with oxygen (O2), producing carbon dioxide (CO2) and water (H2O). From the chemical equation, the reactants side contains one ethanol molecule containing six hydrogen atoms. Hence, in terms of reactants, the number of hydrogen atoms involved in the equation is 6.
