2. Consider sodium carbonate (Na2CO3). How many sodium atoms are present in 5.08 g of Na2CO:?...
A 2.500 grams sample of a mixture of sodium carbonate (Na2CO3) and sodium chloride (NaCl) is dissolved in 25.00 mL of 0.798 M HCl (hydrochloric acid). Some acid will remain after the treatment of the sample. If 28.7 mL of 0.108 M NaOH is required to titrate the excess HCI then how many moles of sodium carbonate were present in the original sample? Hint: The moles of Na2CO3 present is equal to one- half the number of H30* moles and...
Suppose that you massed out 3.50 g of sodium carbonate, Na2CO3. How many moles would you have? *
1. How many moles of sodium carbonate are there in 65.3 grams of Na2CO3?
What is the theoretical yield of sodium carbonate (Na2CO3) product, in moles, if all 3.21 g of sodium bicarbonate starting material reacts? Show your work below, and record your answer in moles of sodium carbonate. Hint: Use the mole ratio from the balanced chemical equation.
For the reaction Na2CO3+Ca(NO3)2⟶CaCO3+2NaNO3 how many grams of calcium carbonate, CaCO3, are produced from 19.9 g of sodium carbonate, Na2CO3?
A 5.37 g mixture of sodium chloride and sodium carbonate is heated to decompose the sodium carbonate into sodium oxide and carbon dioxide according to the following chemical equation. Na2CO3 → Na2O + CO2 The sodium chloride will not decompose. If the final mixture has a mass of 4.03 g, what was the percent sodium carbonate in the original mixture? Hint: Consider the Law of Conservation of Matter - the mass of reactants must equal the mass of products. However,...
