Question

ПОЖАЛУЙСТА ,ПОМОГИТЕ:( СРОЧНО НАДО) *осуществите реакции в соответствии с сокращенными ионно-молекулярными уравнениями:*а) Ва 2 SO2-4 =BaSO4↓б) H OH- =H2Oв)CO2-3 2H = CO2↑ H2O

Answer 1

BaCl2 + CuSO4 = CuCl2 + BaSO4
KOH + HNO3 = KNO3 + H2O
Na2CO3 + 2HCl = 2NaCl + CO2 + H2O

Answer 2

Reaction Equations:

a) Ba2+ + SO42- = BaSO4↓ b) H+ + OH- = H2O c) CO32- + 2H+ = CO2↑ + H2O

Explanation:

a) The given equation represents a precipitation reaction between barium ions (Ba2+) and sulfate ions (SO42-). When these ions combine, they form solid barium sulfate (BaSO4) which precipitates out of the solution. The balanced equation for this reaction is:

Ba2+ + SO42- = BaSO4↓

b) The given equation represents a neutralization reaction between hydrogen ions (H+) and hydroxide ions (OH-). When these ions combine, they form water (H2O). The balanced equation for this reaction is:

H+ + OH- = H2O

c) The given equation represents the reaction between carbonate ions (CO32-) and hydrogen ions (H+). When these ions combine, they form carbon dioxide gas (CO2) which is released as a product, and water (H2O). The balanced equation for this reaction is:

CO32- + 2H+ = CO2↑ + H2O

Please note that the arrows in the equations indicate the direction of the reaction. The downward arrow (↓) represents the formation of a precipitate, and the upward arrow (↑) represents the release of a gas.

I hope this helps! Let me know if you have any further questions.
