Does anyone know the answer to this chemistry how much hcl is made when 2g of hydrogen reacts? h2+cl2-> 2hcl

146g

Explanation:

We're assuming the reaction is occurring with excess chloride. First convert hydrogen mass to moles using molar mass - you need to work with numbers for these sorts of questions:

n = m / MM

n = 2g / 1g/mol

n = 2mol

Now use your stoich ratio to find how many moles of HCL are produced. There are 2 moles of HCl produced for every 1 mole of H2 reacted so:

x HCl / 2 mol H2 = 2 HCl / 1 H2

x = 4mol HCl

Now convert this back into mass using the molar mass of HCl:

m = n x MM

m = 4mol x 36.5g/mol

m = 146g

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

-love shrooms

you gotta add the following molecules so we can give u an answer
