yes it does
Mass-mass stoichiometry: involves converting the mass of one substance to the mass of another in a chemical reaction. Volume-volume stoichiometry: involves converting the volume of one substance to the volume of another in a chemical reaction. Mass-volume stoichiometry: involves converting the mass of one substance to the volume of another in a chemical reaction. Limiting reactant stoichiometry: involves determining which reactant limits the amount of product formed in a chemical reaction. Percent yield stoichiometry: involves calculating the efficiency of a chemical reaction by comparing the actual yield to the theoretical yield. Excess reactant stoichiometry: involves calculating the amount of reactant left over after a chemical reaction is complete.
The formula for this equation is:2Mg + O2 ---> 2MgOOriginally, the weight you have is just the magnesium only. Although the oxygen is part of the reactants, you are not measuring it. Although, through the chemical reaction, the oxygen becomes bonded to the magnesium. Then you weigh the magnesium withthe added oxygen. So the final weight should be more than the original.2 Mg (s) + O2 (g) → 2 MgO (s)APEX :)
In a chemical reaction, the total mass of the reactants will always be equal to the total mass of the products (law of conservation of mass). Therefore, the mass of the substance in any state (solid, liquid, or gas) will remain the same before and after the reaction.
To determine the mass of CuO formed, first calculate the moles of each reactant using their molar masses. Then, determine the limiting reactant by comparing the moles of CuO that could be formed from each reactant. Finally, use the limiting reactant to calculate the mass of CuO formed based on the balanced chemical equation.
The mass of 2 moles of H2 gas = 2.00 x 2 = 4.00 g
It is possible to have ten grams of anything. Specifying the total weight tells you nothing about which reactant you have or what reaction it will undergo.
This is the law of mass conservation.

Balanced chemical equation along with the stoichiometric ratios derived from that chemical reaction. A + B --> 2C mass of A * 1/molar mass of A = moles of A Moles of A * 2 moles of C/mole of A = moles of C Moles of C * molar mass of C = mass of C Also, you must think about limiting reagents, because if there is not enought reactant B to react with the amount of reactant A then the amount of reactant B will limit the production of product C!
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
The amount of matter involved in a chemical reaction does not change. The total mass of the reactant must equal the total mass of the products.
To predict the mass of a reactant or product in a chemical reaction, you would need the balanced chemical equation for the reaction, as it provides the stoichiometric ratio between the reactants and products. Additionally, you would need the molar mass of the specific substance you are interested in. With this information, you can calculate the mass using stoichiometry and molar ratios.

The molar mass of S8 is 256 g/mol. To calculate the maximum mass of S8 that can be produced, first determine the limiting reactant by converting the masses of the reactants to moles. Then, use the stoichiometry of the reaction to find the mass of S8 produced from the limiting reactant.
The Limiting Reactant is the smaller number once you compare the two reactants with one product. The product that you are comparing them both with must be the same. The Excess Reactant is the larger number, or the amount left over in the chemical reaction.

It doesnt. Law of Conservation of Mass.
