We are given the starting amount of Al metal to be used. This will be the starting point of the calculations. We do as follows:
74.00 g ( 1 mol / 26.98 g ) ( 1 mol Al2O3 / 2 mol Al ) ( 101.96 g / 1 mol ) = 139.83 g Al2O3 produced
Hope this answers the question. Have a nice day.
Answer:
Double Replacement
Explanation:
Let's consider the following balanced reaction that occurs between aluminum sulfate and tripotassium phosphate.
Al₂(SO₄)₃ + 2 K₃PO₄ ⇒ 2 AlPO₄ + 3 K₂SO₄
This is a double replacement reaction because both salts exchange their cations and anions. So, PO₄³⁻ takes the place of SO₄²⁻ in Al₂(SO₄)₃ and SO₄²⁻ takes the place of PO₄³⁻ in K₃PO₄.
Answer: <em>Running water, even at a trickle, helps prevent pipes from freezing. If you decide to use fuel-burning equipment, such as a kerosene heater, ensure it is vented to outside and kept clear of any vents. Keep garage doors closed if there are water supply lines in the garage.</em>
