Question

Знайдіть відносну густину ацетилену C2H2 а) за воднем Н2 б) за повітрям

Answer 1

Ответ:

а) D C₂H₂\H₂ =13

б)D C₂H₂\пов. = 0,896

Объяснение:

Mr(C₂H₂) = 12·2+1·2 =26

Mr(H₂) = 1·2 = 2

Mr(пов) = 29

а) DC₂H₂\H₂ = Mr(C₂H₂)\Mr(H₂) = 26\2=13

б)DC₂H₂\пов. = Mr(C₂H₂)\Mr(пов) = 26\29=0,896

Answer 2

Relative Density of Acetylene (C2H2)

The relative density of a substance is the ratio of its density to the density of a standard substance, typically water or air.

a) Relative Density of Acetylene (C2H2) Compared to Water (H2O): The relative density of acetylene (C2H2) compared to water is less than 1, indicating that acetylene is lighter than water.

b) Relative Density of Acetylene (C2H2) Compared to Air: The relative density of acetylene (C2H2) compared to air is greater than 1, indicating that acetylene is heavier than air.

The specific numerical values for the relative density of acetylene compared to water and air can be found in scientific databases or reference materials.
