How do I solve this problem step by step? 2.) Calculate the mass (in grams) of H2 produced from the reaction of 34.23 g of Mg with excess HCI. Mg(s) + HCI (aq) → MgCl2 (aq) + H2 (g)
How can i calculate the enthalpy of reaction for both neutralization reactions (HCL + NaOH) and (Citric acid + NaHCO3) with units of Kj/mol? Enthalpy of formation: Hcl (aq): -167.2 kj/mol NaOH (aq): -469.6 kj/mol citric acid (aq): not sure NaHCO3 (s): -947.7 kj/mol neutralization reactions that occur when an acid reacts with a base. HCI (aq) + NaOH (aq) → H20 (1) + NaCl (aq) HzC6H50, (citric acid) (aq) + 3 NaHCO3 (s) → Na2C8H:07 (aq) + 3 CO2...
please hep with clear steps ( SO I can learn how to do this) 1. If 5.00 g of pure Na2CO3is treated with HCl solution, how many grams of NaCl will be produced if the water is subsequently evaporated from the salt? Molar Mass ofNa 2CO3= 105.99 g/mol. 2. If 5.00 g of pure NaHCO3 is treated similarly, how many grams of NaCl will result?Molar Mass of NaHCO3= 84.01g/mol. 3. What volume of 3.00 M HCl would be required to...
Given the data below, how many grams of NaCl would you expect to be formed in the reaction of excess HCl with the Na,CO3?

A 10.0 g solid sample contains 14.0% NaHCO3 by mass; the rest is NaHSO4. Find the mass of CO2 gas it will produce if treated with an excess of hydrochloric acid. Molar masses: M(NaHCO3) = 84.007 g/mol, M(CO2) = 44.01 g/mol. The gas-evolution reaction: NaHCO3(s) + HCl(aq) = NaCl(aq) + H2O(l) + CO2(g). (A) 0.733 g (B) 1.47 g (C) 2.67 g (D) 4.51 g (E) 5.24 g
1. Consider the reaction: NaHCO3(aq) + HCl(aq) → NaCl(aq) + CO2(g) + H2O(l) Question: 0.056 moles of NaHCO3 are reacted with excess HCl. 2.267 g of CO2 were produced. What is the percent yield of CO2?
Use mass-to-mass stoichiometry, calculate the theoretical yield of NaCl in reaction NaHCO3+HCl —> NaCl+ H2O+CO2 obtained mass of NaHCO3 0.372 grams mass of NaCl got from the reaction 0.148 grams
