масою 120 г з масовою часткою кислоти 10%?



Answer :

I can help you with that. To calculate the mass of the precipitate formed when barium chloride reacts with a solution of sulfuric acid, we need to follow these steps: 1. Determine the limiting reactant by calculating the number of moles of each reactant present. This can be done by dividing the mass of each substance by its molar mass. 2. Write the balanced chemical equation for the reaction between barium chloride (BaCl2) and sulfuric acid (H2SO4) to find the mole ratio of reactants. 3. Identify the limiting reactant based on the mole ratio obtained in step 2. 4. Calculate the theoretical yield of the precipitate (barium sulfate, BaSO4) using the limiting reactant. 5. Convert the theoretical yield in moles to grams to find the mass of the precipitate formed. By following these steps, you can accurately determine the mass of the precipitate formed in the reaction between barium chloride and a solution of sulfuric acid with a given mass and concentration.
