Answer:
sodium sulfite) Na2SO3 + HCl (hydrochloric acid). This reaction is a gas evolution reaction. The products are sodium chloride (NaCl), sulfur dioxide (SO2) and water (H2O). Sulfurous Acid (H2SO3) is produced as an intermediate in this reaction.
Explanation:
Answer:
1040
Explanation:
you can use the mole to mole ratios of aluminum chloride and hydrogen gas,you first have to find the number of moles of hydrogen gas..the number of moles of hydrogen gas are 11.7(23.4/2)
2AlCl3+3H2
2 : 3
x :11.7
3x/3=23.4/3
x=7.8g/mol
then find the number of grams of aluminum chloride
m=n×mr
=7.8×133.341
=1040g
I hope this helps and sorry if it's wrong
