Answer:
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
The ratio of moles of AI(NO3)3 to moles Na2CO3 in the reaction is 2:3
In the reaction 2 moles of AI(NO3)3 reacted with 3 moles Na2CO3 so the ratio of the moles is 2 is to 3 represented as 2:3

(1) Ar is your answer. Argon is a noble gas, which is stable in its standard valence electron configuration because it already completed its valence shell following the octet rule.
Answer:
the company has also fished
I believe that would be a parasitism because one organism benefits yet the other is harmed.
