✔ 最佳答案
2 HCl + K2SO3 → H2O + SO2 + 2 KCl(If we're talking about "completely" here, there's no equilibrium.)
(0.200 L) x (0.255 mol/L HCl) x (1/2) x (158.2604 g K2SO3/mol) = 4.04 g K2SO3

in case you propose x divided by 2 = 5, then the reply (x) is 10. you need to do the different of the equation to get the respond to x. so the mission is branch, you want to do multiplication. 5x2=10. so plug 10 back into the mission replacing x: 10 divided by 2=5
