Admin How do the mass of the products compare to the mass of the reactants in a chemical reaction?
In a chemical reaction, how does the mass of the reactants compare with the mass of the products? During a chemical reaction, the mass of the products is always equal to the mass of the reactants.
Is the mass of reactants greater than the mass of products?
Explanation: According to the Law of Conservation of Mass, mass cannot be created or destroyed. Therefore in any chemical reaction the mass of the products must equal the mass of the reactants.
How do you find the mass of a reactant?
Worked Example of Using Mole Ratio to Calculate Mass of Reactant or Product
- mass O2 = moles(O2) × molar mass(O2) (a) Calculate moles(Mg) = mass(Mg) ÷ molar mass(Mg) moles(Mg) = 12.2 ÷ 24.31 = 0.50 mol.
- mass MgO = moles(MgO) × molar mass(MgO) (a) Calculate moles Mg. moles(Mg) = mass(Mg) ÷ molar mass(Mg)
What should the mass of the products of a reaction equal?
The mass of the products should equal the mass of the reactants. What does the law of conservation of mass tell about the mass of a reactants and products in a reaction before a chemical reaction and the ass of the products of the mass of products after a chemical?
How does the law of Conservation of mass apply to chemical reactions?
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction. How is law of conservation of mass relate to balancing reactions?
What happens to atoms before and after a chemical reaction?
The same number and type of each atom will always be present before and after a chemical reaction takes place. Some of the atoms present before the reaction will always be lost during a chemical reaction. Some of the atoms will always be changed into a different type of atom by a chemical reaction.
