In an experiment, 645 g of sulfuric acid are added to 954 g of sodium dichromate to produce sodium sulfate and hydrogen dichromate. What is the reactant in excess and what mass of excess reactant is left over?

Step 1
The products are sodium sulfate (Na₂SO₄) and chromium (III) sulfate (Cr₂(SO₄)₃). The balanced equation is: \[ 3 \text{H}_2\text{SO}_4 + \text{Na}_2\text{Cr}_2\text{O}_7 \rightarrow 3 \text{Na}_2\text{SO}_4 + \text{Cr}_2(\text{SO}_4)_3 \] Show more…

Sodium dichromate, Na2Cr2O7, can be made by reacting sodium chromate, Na2CrO4, with sulfuric acid. 2Na2CrO4 + H2SO4 → Na2Cr2O7 + Na2SO4 + H2O a. What is the minimum volume of 18.0 M H2SO4 necessary to react completely with 15.345 kg of sodium chromate, Na2CrO4? b. What is the maximum mass, in kilograms, of sodium dichromate that can be formed from the reaction of 203 L of 18.0 M H2SO4?

Aqueous sulfuric acid (H2SO4) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium sulfate (Na2SO4) and liquid water (H2O). Suppose 42.2 g of sulfuric acid is mixed with 65. g of sodium hydroxide. Calculate the minimum mass of sulfuric acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.

Na2Cr2O7 + 2H2SO4 → 2CrO3 + 2NaHSO4 + H2O What is the minimum volume of 16.6 M H2SO4 solution necessary to react with 853.0 kg of sodium dichromate? What is the maximum mass of sodium hydrogen sulfate, NaHSO4, that can be formed from the reaction of 853.0 kg of sodium dichromate with 390.0 L of 16.6 M H2SO4?
