Answer:
A
Explanation:
How many moles of HCI will just react with 0.424 g Ba(OH)2?
A) 4.94 x 10 mol
Answer:
48 g S
Explanation:
Step 1: Define
Molar Mass of Sulfur (S) - 32.07 g/mol
Step 2: Use Dimensional Analysis
= 48.105 g S
Step 3: Simplify
We have 2 sig figs.
48.105 g S ≈ 48 g S
It depends on which manner the formulae is being asked but the answer is: KNO3
After first half-life you will have 100/2=50g. After second half-life you will have 50/2=25g.
