Express your answer as a balanced chemical equation. Identify all of the phases in your answer.
SpyIntel [72]

Answer:

H₂S(aq)+ 2 LiOH(aq) → Li₂S(aq) + 2 H₂O(l)

6 HI(aq) + 2 Al(s) → 2 AlI₃(aq) + 3 H₂(g)

2 H₂SO₄(aq) + TiO₂(s) → Ti(SO₄)₂(aq) + 2 H₂O(l)

H₂CO₃(aq) + 2 LiOH(aq) → Li₂CO₃(aq) + 2 H₂O(l)

Explanation:

H₂S(aq)+ 2 LiOH(aq) → Li₂S(aq) + 2 H₂O(l)

This is a neutralization reaction. The products are salt and water.

6 HI(aq) + 2 Al(s) → 2 AlI₃(aq) + 3 H₂(g)

This is a single displacement reaction.

2 H₂SO₄(aq) + TiO₂(s) → Ti(SO₄)₂(aq) + 2 H₂O(l)

This is a neutralization reaction. The products are salt and water.

H₂CO₃(aq) + 2 LiOH(aq) → Li₂CO₃(aq) + 2 H₂O(l)

This is a neutralization reaction. The products are salt and water.

Which of the following indicates a strong base is present?
oksian1 [2.3K]
<h3>B</h3><h3>brainliest! These bases completely dissociate in solutions of 0.01 M or less. The other bases make solutions of 1.0 M and are 100% dissociated at that concentration. There are other strong bases than those listed, but they are not often.</h3>

Strong bases are bases which completely dissociate in water into the cation and OH- (hydroxide ion). The hydroxides of the Group I (alkali metals) and Group II (alkaline earth) metals usually are considered to be strong bases. These are classic Arrhenius bases. Here is a list of the most common strong bases.

LiOH - lithium hydroxide

NaOH - sodium hydroxide

KOH - potassium hydroxide

RbOH - rubidium hydroxide

CsOH - cesium hydroxide

*Ca(OH)2 - calcium hydroxide

*Sr(OH)2 - strontium hydroxide

*Ba(OH)2 - barium hydroxide
