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.
7. Given a buffer solution of sodium hydrogen carbonate (NaHCO3) and sodium carbonate (Na2CO3). a. Calculate the pH of this buffer solution when 0.100M sodium hydrogen carbonate (NaHCO3) and 0.100M sodium carbonate (Na2CO3). (Ka = 7.94 x 10-7) b. Calculate the new pH value of this buffer solution when 1.00mL of 0.100M NaOH is added to to 100mL of this buffer
What volume, in mL, of 0.1000M sodium carbonate, Na2CO3, is necessary to make 10.00g of magnesium carbonate, MgCO3, in the following reaction? MgCl2 (aq) + Na2CO3 (aq) --> MgCO3 (s) + 2 NaCl (aq)
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,...
Write a balanced equation for the reaction between sodium carbonate (Na2CO3) and hydrochloric acid (HCI). Calculate the theoretical yield of the gas (CO2) that should be produced from the mass of Na2CO3 used. Use dimensional analysis.
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...
