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
Uranium, which is number 92
How many inches are in 6.32 cm=2.48818898
Answer:
Option C
Explanation:
A buffer aqueous solution consists of
a) either a weak acid along with its conjugate base
b) or a weak base along with its conjugate acid.
This is used to prevent change in the pH of a solution whenever an acid or a base is added. The pH of a buffer depends upon the ratio of base to acid and this ratio is determined by the Ka value and Henderson-Hasselbalch equation. An ideal buffer has equal amounts of acid and conjugate base
Hence, option C is correct
Answer:
0.050 mol
Explanation:
The reaction that takes place is:
Then we convert 0.050 moles of phosphoric acid into moles of ammonium phosphate, using the stoichiometric coefficients of the reaction:
- 0.050 mol H₃PO₄ *
= 0.050 mol (NH₄)₃PO₄
Thus, the complete reaction of 0.050 moles of phosphoric acid would produce 0.050 moles of ammonium phosphate.
