So, we reacted metal hydrogen carbonate with HCl to find what the metal is.

Data:

Mass of metal hydrogen carbonate = 2.6 g

Mass of 40 mL HCl + 100 mL cylinder = 80.5 g

After the reaction:

Mass of acid solution = 39.6g

Mass of reactants = 42 g

Mass of products = 40.8 g

Mass of Co2 = 1.4 g = 0.031 mol CO2

Now, we need to do the following:

a) write a balanced equation: analyzing the various ways we can combine the ions to form compounds in writing the chemical equation.

b)number of moles of metal hydrogen carbonate

c)molecular weight of the metal hydrogen carbonate

d)atomic mass of the metal

Thank You Very Very Much…..
