Answer 2

Chemical Reaction Analysis

When considering the interaction of the listed substances with sulfuric acid and potassium hydroxide, it's important to understand the potential reactions involved.

Hydroxide of Barium (Ba(OH)2) and Sulfuric Acid (H2SO4):

The reaction between barium hydroxide and sulfuric acid can be represented by the following equation: ``` Ba(OH)2 + H2SO4 → BaSO4 + 2H2O ``` This reaction forms barium sulfate and water.

Carbon Dioxide (CO2) and Potassium Hydroxide (KOH) Solution:

When carbon dioxide reacts with potassium hydroxide solution, it forms potassium carbonate and water: ``` CO2 + 2KOH → K2CO3 + H2O ``` This reaction results in the formation of potassium carbonate and water.

Nitric Acid (HNO3) and Zinc (Zn):

The reaction between nitric acid and zinc can be represented as follows: ``` Zn + 2HNO3 → Zn(NO3)2 + H2 ``` This reaction produces zinc nitrate and hydrogen gas.

Zinc Hydroxide (Zn(OH)2) and Potassium Hydroxide (KOH) Solution:

When zinc hydroxide reacts with potassium hydroxide solution, it forms a complex compound. The specific chemical equation for this reaction is not readily available in the provided search results.
