Question

Ba→BaO→X→BaSO4 Яка речовина може бути Х? * а) Вa(NO3)2 б) Ba(OH)2 в) BaSO4 г) BaO2

Answer 1

Объяснение:

2Ba + O2 = 2BaO

BaO + H2O = Ba(OH)2 это Х

Ba(OH)2 + H2SO4 = BaSO4↓ + H2O

Answer 2

Chemical Reaction and Product Formation

The chemical equation provided is a representation of a reaction involving the transformation of Barium (Ba) into Barium Sulfate (BaSO4). The missing substance denoted by "X" in the equation is the reactant that combines with Ba to form BaSO4.

The options for the substance "X" are: * a) Ba(NO3)2 * b) Ba(OH)2 * c) BaSO4 * d) BaO2

To determine the correct substance, we need to consider the chemical properties and reactivity of the substances involved in the reaction.

Analysis and Solution

The balanced chemical equation for the reaction is as follows: ``` Ba + X → BaSO4 ``` In this reaction, Barium (Ba) reacts with the unknown substance (X) to form Barium Sulfate (BaSO4).

To identify the correct substance "X," we can consider the solubility rules for common ionic compounds. Barium sulfate (BaSO4) is insoluble in water, which means it forms a precipitate when mixed with certain aqueous solutions.

Based on the solubility rules: * Barium nitrate (Ba(NO3)2) is soluble in water. * Barium hydroxide (Ba(OH)2) is sparingly soluble in water. * Barium sulfate (BaSO4) is insoluble in water. * Barium peroxide (BaO2) is insoluble in water.

Therefore, the correct substance "X" that can lead to the formation of BaSO4 is c) BaSO4.

Conclusion

The substance "X" in the given chemical equation, which leads to the formation of Barium Sulfate (BaSO4) when combined with Barium (Ba), is c) BaSO4.
