Your answer would be "Chemical Change"
Answer:
0.5133805136 moles.
Explanation:
1 gram of Al2(Co3)3 equals 0.0017112683785004 moles, we need the amount of moles produced in 300 grams of Al2(CO3)3, so we have to multiply 1 gram of Al2(CO3)3 times 300: 0.0017112683785004 x 300, in conclusion,
300 grams of Al2(Co3)3 equals 0.5133805136.

Answer: a substance that increases the hydroxide ion concentration of a solution
Explanation: According to Arrhenius concept, an acid is a substance which donates hydronium ions ![[H^+]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D)
ions when dissolved in water and base is a substance which donates hydroxide ions ![[OH^-]](https://tex.z-dn.net/?f=%5BOH%5E-%5D)
ions in water.
According to the Bronsted Lowry conjugate acid-base pair, an acid is a substance that donates protons and a base is a substance that accepts protons.
According to Lewis concept, an acid is the substance which accepts electron pairs and abase is a substance which donates electron pairs.
Thus a substance that increases the hydroxide ion concentration of a solution is an Arrhenius base.
