Question

which law of chemical combination or base formation of Cu2O and Cuo

Answer 1

law of chemical reaction is ddr

Answer 2

Answer: These two compounds follow law of multiple proportion.

Explanation:

Law of multiple proportions: This law states that when two elements combine together to form two or more compounds in more than one proportion.

For given compounds, $Cu_2O\text{ and }CuO$

Mass of Copper = 63.5 g/mol

Mass of oxygen = 16 g/mol

• Ratios of mass of elements in $Cu_2O$

Mass of Copper = (2 × 63.5) = 127 g/mol

Mass of Oxygen = 16 g/mol

Mass ratio of copper and oxygen in $Cu_2O$ is 127 : 16

• Ratios of mass of elements in $CuO$

Mass of Copper = 63.5 g/mol

Mass of Oxygen = 16 g/mol

Mass ratio of copper and oxygen in $CuO$ is 63.5 : 16

As, the mass of oxygen is fixed, so the mass ratio of copper in both the compounds must be present in the lowest whole number ratio.

Mass ratio of copper in the given compounds =  63.5 : 127

Reducing this ratio in the lowest whole number ration = 1 : 2

Hence, the two given compounds follows Law of multiple proportions.
