Explanation:
First conversion factor: moles of SO₄ per mole of Al₂(SO₄)₃.
3 mol SO₄ / mol Al₂(SO₄)₃
Second conversion factor: moles of S per mole of SO₄.
1 mol S / mol SO₄
Altogether:
(3 mol SO₄ / mol Al₂(SO₄)₃) × (1 mol S / mol SO₄) = 3 mol S / mol Al₂(SO₄)₃
Answer:
protons and neutrons have different charges but they have approximately the same mass
Answer:
The stomach, gallbladder, and pancreas work together as a team to perform the majority of the digestion of food. Food entering the stomach from the esophagus has been minimally processed — it has been physically digested by chewing and moistened by saliva, but is chemically almost identical to unchewed food
