Question

melts above 500 c, is a physical property NaHCO3 only O NaCl only NaHCO3 and NaCl neither NaHCO3 or NaCl QUESTION 5 points Save Answe Which of the following is the correct chemical equation to describe the reaction between hydrochloric acid and sodium bicarbonate? O HCl (aq) + NaHCO3 (s)- NaCl (aq) + H2O() O 2HCl(aq) + Na2CO3 (s) 2NaCl (aq) + H2O(l) O HCI(aq) + NaHCO3 (s)- NaCl (aq) + H2O(l) + CO2 (g) O HCl (aq) + 2Na2CO3 (s) 2NaCI(aq) + H2CO3(aq) QUESTION 6 2 points Save Answer bicarbonate? Which of the following is the correct chemical equation to describe the decompostion of sodum sodium bicarbonate does not decompose 2NaHCOg (s) Na2CO3 (S) + CO2 (g) + H29(g) 2NaHCOg (s) Na2CO3 (S) + CO2 (g) + H2(g) NaHCO3 (s)-* Na (S) + CO2 (g) + H2(

Explanation / Answer

(5) correct chemical equations for the reaction of NaHCO3 with HCl is

NaHCO3 + HCl = NaCl + CO2 + H2O

(6) Correct chemical equations for the decomposition of Sodium bicarbonate

2 NaHCO3 ------> Na2CO3 + CO2 + H2O
