WebSample calculations Example 1 Calcium carbonate and dilute hydrochloric acid react together according to this equation: CaCO 3 + 2HCl CaCl 2 + H 2 O + CO 2 What mass of … WebNitrogen and hydrogen react together to make ammonia. N 2 + 3H 2 → 2NH 3. If 2.0 g of hydrogen is added to 12.0 g of nitrogen which substance is the limiting reactant and how much of the excess reactant remains? cindy greaves university of utah

Lesson Worksheet:Reaction Masses Nagwa

WebStudents should have recorded the following masses: mass 1 = crucible + lid mass 2 = crucible + lid + magnesium mass 3 = crucible + lid + product This should allow them to calculate the mass of the mass of the magnesium (mass 2 – mass 1) and the mass of the product (mass 3 – mass 1). Webmass NaOH = 40 x 500 = 20000 g 6) →What mass of carbon dioxide is formed when 7.41 g of copper(II) carbonate decomposes on heating? CuCO 3 CuO + CO 2 moles CuCO 3 = !.!"!"#.! = 0.0600 mol moles CO 2 = 0.060 mol mass CO 2 = 44 x 0.060 = 2.64 g REACTING MASS CALCULATIONS 1 WebCalculate stoichiometric reacting masses and reacting volumes of solutions; solution concentrations will be expressed in mol / dm 3. (Calculations involving the idea of limiting reactants may be set.) You can find the number of moles of atoms, molecules or ions using the following formula: cindy green from joplin mo
