Answer:
the water is diffrent because it is now a gas not a liquid
Explanation:
Answer:
b. AZ BX
Explanation:
A⁺, B⁺, X⁻, Y⁻ and Z⁻
AX(aq)+BY(aq)→no precipitate
AX(aq)+BZ(aq)→precipitate.
AX(aq)+BY(aq)→no precipitate:
A⁺ (aq) + X⁻ (aq) + B⁺ (aq) + Y⁻ (aq) → AY (aq) + BX (aq)
AX(aq)+BZ(aq)→precipitate:
A⁺ (aq) + X⁻ (aq) + B⁺ (aq) + Z⁻ (aq) → AZ (s) + BX (aq)
Considering the reactions above, the insoluble specie is AZ.

Answer:
2 Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + 3 H₂(g)
Explanation:
Let's consider the unbalanced equation for the single replacement reaction between Al and H₂SO₄.
Al(s) + H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + H₂(g)
We will begin balancing S atoms by multiplying H₂SO₄ by 3.
Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + H₂(g)
Then, we balance Al atoms by multiplying Al by 2.
2 Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + H₂(g)
Finally, we get the balanced equation by multiplying H₂ by 3.
2 Al(s) + 3 H₂SO₄(aq) ⇒ Al₂(SO₄)₃(aq) + 3 H₂(g)
