Question

3.Установите соответствие между химическими реакциями и отношениями объемов газов: химическими реакциями Отношение объемов газов а) Н2+Вr2 = 2HBr 1:3:2б) N2+3H2=2NH3 1:1:2в) С+О2=СО2 2:1:2г) 2Н2+О2=2Н2О 1:1:1​

Answer 1

Ответ:

Объяснение:

а) 1:1:2

Б) 1:3:2

в) 1:1:1

г) 2:1:2

Answer 2

Correspondence between chemical reactions and gas volume ratios:

a) 2HBr = H2 + Br2 - The volume ratio of gases in this reaction is 1:3:2. [[1]]

b) N2 + 3H2 = 2NH3 - The volume ratio of gases in this reaction is 1:1:2. [[2]]

c) C + O2 = CO2 - The volume ratio of gases in this reaction is 2:1:2. [[3]]

d) 2H2 + O2 = 2H2O - The volume ratio of gases in this reaction is 1:1:1. [[4]]
