Question

Перетворіть схемні на рівняння, поставши коефіцієнти а) СО+О2=СО2 б)Н2S +О2=SO2+H2O в)Cu+O2=cuO г)SO2+O2=SO3 6)Наведіть приклад розчинів які людина використовує у повсякденному житті

Answer 1

Ответ:

2 CO + O2 → 2 CO2

2 H2S + 3 O2 → 2 SO2 + 2 H2O

2 Cu + O2 → 2 CuO

2 SO2 + O2 → 2 SO3

6. Серед них розчин оцтової кислоти (столовий оцет), водний розчин амоніаку (нашатирний спирт), водний розчин гідроген пероксиду (перекис водню), спиртовий розчин йоду, спиртовий розчин брильянтового зеленого (зеленка) тощо.

Answer 2

Conversion of Chemical Equations to Equations:

a) The balanced chemical equation for the reaction between carbon monoxide (CO) and oxygen (O2) to form carbon dioxide (CO2) is:

2CO + O2 → 2CO2 [[1]]

b) The balanced chemical equation for the reaction between hydrogen sulfide (H2S) and oxygen (O2) to form sulfur dioxide (SO2) and water (H2O) is:

2H2S + 3O2 → 2SO2 + 2H2O [[2]]

c) The balanced chemical equation for the reaction between copper (Cu) and oxygen (O2) to form copper(II) oxide (CuO) is:

2Cu + O2 → 2CuO [[3]]

d) The balanced chemical equation for the reaction between sulfur dioxide (SO2) and oxygen (O2) to form sulfur trioxide (SO3) is:

2SO2 + O2 → 2SO3 [[4]]
