Explanation:
The answer is C. Arrhenius bases increase the concentration of OH- in solution.
Answer:
D. 1,950 g
Explanation:
I completed the test and it is the correct answer!
We have 30% (w/w) HCl this means :
100 g solution contains 30 g HCl
?? g solution contains 7.5 g HCl
By cross multiplication:
Mass of solution =

= 25 g solution
Answer: 67.1 moles of SO2
Explanation:
Since the equation is already balanced, you would just need to cancel out the O2 and multiple the 67.1 mol by the 1 mol of SO2 to get your answer.
