92. A<span>ll </span>isotopes<span> of uranium have the same number of protons</span>
Answer:
9 moles
Explanation:
The balanced chemical equation provided in this question is as follows:
2CH₄ + S₈ → 2CS₂ + 4H₂S
In accordance to the above balanced equation, 1 mole of sulphur (S8) produces 4 moles of hydrogen sulfide (H2S).
Therefore, if 2.25mol of S8 is used, 2.25 × 4 = 9 mol
9 moles of H2S is produced.
Answer:
Distillation
Explanation:
Water vaporizes at lower temperature than the ink pigment so if you heat them, the water evaporates, leaving the ink pigment in the flask
