Reactants are the starting substances and products are the ending substances in a chemical reaction.
The atoms in reactants are arranged one way and are rearranged in a different way to form the products (in other words, reactants are chemically different from products).
The properties of reactants differ from the properties of products. Good answer for E.DG.
If an electron absorbs enough energy it would jump to a higher energy level.
The stoichiometry of the reaction is 5 mols of O2 produces 4 mols of CO2.
1 mol at STP is equivalent to 22.4 liters.
So, 5*22.4 liters of O2 produces 4*22.44 liters of CO2
Then 60 liters of O2 produces 60*4/5 = 48 liters of CO2
The answer to this question is Option 3- Na2O
To determine te volume of the solution given the amount of solute present, we simply divide the amount in moles with the concentration in molarity. First, we make sure the amount of solute is expressed in moles.
moles KCl = 2.55 g KCl / 74.55 g/mol = 0.0342 mol KCl
Volume of solution = 0.0342 mol / 0.155 mol /L = 0.221 L solution or 221 mL of the solution
