What are the 6 types of stoichiometry problems?

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.


When a solid like magnesium burns reacts with oxygen to give an oxide compound and the product is a solid is the easily measurable mass of that product more or less than that of the solid reactant?

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 :)


Which has more mass in a chemical reaction out of solid liquid or gas?

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.


What mass CuO can be formed from the reaction of 18.7 g CuS and 12.0 g of O2?

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.


What is the reactant of the mass?

The mass of 2 moles of H2 gas = 2.00 x 2 = 4.00 g

What is the reactant of 10.0 grams of total mass What is the chemical reaction?

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.


Why amount of reactant and product do not change in a reversible reaction?

This is the law of mass conservation.

If one knows the mass and molar mass of reactant A and the molar mass of product D in a chemical reaction one can determine the mass of product D produced by using the?

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!


will a catalyst change the enthalpy of a reaction in a chemical reaction?

No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!


What is is the principle of conservation of mass?

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.


What information do you need to predict the mass of a reactant or product in a chemical reaction?

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.

What is the maximum mass of S8 that can be produced by combining 75 grams of each reactant?

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.


What is the limiting reactant reagent and what is excess reagent in recrystallization?

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.

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.


How does the mass of a melting solid affect the closed systems mass?
