Sorry I meant hydrogen!

Mg2+ + 2HCl --> MgCl2 + H2 (gas)

Okay, hydrogen. As you can see in the above equation, for one atom of magnesium you'll produce two atoms of hydrogen.

Let's work out how much hydrogen you'll get in grams.
And let's say that you have 1 gram of Mg. First, what you need to do is work out how many atoms are in 1 gram of Mg.

This is easy. Simply:

1 / atomic mass x Avagadro's constant = number of atoms.

For Mg, this equals:

1 / 24.31 x 6.0221415×10^23 = 0.2477228 x 10^23 atoms.

We know that for every atom of Mg you'll produce 2 atoms of hydrogen. So, that means you'll produce:

2 x 0.2477228 x 10^23 = 0.4954456 x 10^23 atoms of hydrogen.

To work out how much 0.4954456 x 10^23 atoms of hydrogen weighs you just calculate, like this:

0.4954456 / 6.0221415 x 1.008 = 0.0829 grams.

And that's it. 1 gram of Mg will produce 0.0829 grams of hydrogen.

No carbon dioxide is produced as there is no carbonate ion present in either of the reactants.

Do a minimum of three titrations and really calculate the recommend, yet upon getting any outliers (many situations your first attempt) then discard it. now and back you may be requested to maintain doing titrations till you get 2 "concordant" outcomes, this skill interior of, 0.a million ml of one yet another then you really might want to take the accepted of those 2.

hydrogen gas comes out and the follows like this:

Mg + 2HCL = MgCL2 + H2

you would have to know how much Mg and HCl you had

you'd then have to use stoichiometry

either post another question with the given amounts or send me an email and i'll walk you through it

No CO2 is produced, H2 is the only gas.
