What is the correct conclusion?Class 11Some Basic Concepts of ChemistryLaws of chemical combinationEasyChemistryIn a closed system, 16 g of reactants produce a 10 g solid and a gas. What is the mass of the gas if these are the only products?Class 11Some Basic Concepts of ChemistryLaws of chemical combinationEasyChemistryIn a closed system, 9 g and 11 g of reactants form two products. If one product has a mass of 13 g, what is the mass of the other product?Class 11Some Basic Concepts of ChemistryLaws of chemical combinationEasyChemistryA 9 g compound contains 3 g of component A. What is the mass of component B if the compound contains only A and B?Class 11Some Basic Concepts of ChemistryLaws of chemical combinationEasyChemistryIf 27 grams of water contains 3 grams of hydrogen, what is the mass of oxygen?Class 11Some Basic Concepts of ChemistryLaws of chemical combinationEasyChemistryIn a closed vessel, 40 g of reactants react completely to form only a solid and a gas. If the solid product has a mass of 28 g, what is the mass of the gas product?Class 11Some Basic Concepts of ChemistryLaws of chemical combinationEasyChemistryIn a closed system, the total mass of the products is 30 g, and the total mass of the reactants is also 30 g. Which law does this demonstrate?Class 11Some Basic Concepts of ChemistryLaws of chemical combinationEasyChemistryIn a closed system, two reactants form 18 g of products.
