j

One of the reactants used in this experiment is NaHCO3 which is called ____________.

Question 2 options:

Sodium Carbonate

Sodium Bicarbonate

Sodium Hydrogen Carbon Oxide

Save

Question 3 (1 point)

In both chemical equations listed in the experiment the products are absent but there are three products that are formed in both reactions. In the reaction below, what product belongs in the blank?

Question 3 options:

Save

Question 4 (1 point)

The products from question #3 are the same products formed when Sodium Carbonate (Na2CO3) reacts with HCl however the resulting equation is unbalanced. What is the coefficient that needs to be in front of both the HCl and NaCl formulas? (To figure this question out, write out the complete chemical equation for Na2CO3 reacting with HCl to form the three products from question #3 and then balance the equation).

Question 4 options:

3

Question 5 (1 point)

How much NaHCO3 and Na2CO3 are you to use in this experiment?

Question 5 options:

3.5 g

350 g

0.035 g

0.35 g

Sodium Carbonate

Sodium Bicarbonate

Sodium Hydrogen Carbon Oxide

Explanation / Answer

sodium bicarbonate

The balanced reaction is NaHCO3 + HCl---- > NaCl + H2O + CO2 .Hecne the third product is CO2

The balanced reactino of Na2CO3 and HCl is

Na2CO3+2 HCl---> 2NaCl + H2O + CO2

The coefficienta to be put are 2 infront of NaCl and 1 in front of H2O

NaHCO3 and Na2CO3 to be used are 3.5, 350, 0.035 and 0.35 gms (since how much are the products formed were not specified)
