composition throughout
b mixtures can be separated using physical
properties
С
Substances must combine in specific proportions
d the components keep their physical properties

Answer 1

The false statements from the option regarding mixtures are ; ( A and C )

• They are all mixed uniformly and have an even composition throughout
• Substances must combine in specific proportions ( C )

Mixtures are made by the physical combination of substances at varying or at the same proportions. mixtures made up of similar proportion of substances are termed homogenous mixtures, while the varying proportions in substances contained in a mixture leads to a heterogenous mixture.

Mixtures do not bond chemically therefore they retain their physical properties and can be separated based on their physical properties. also some mixtures are not mixed up uniformly ( heterogenous mixtures ).

Hence we can conclude that the false statements regarding mixtures are ;They are all mixed uniformly and have an even composition throughout   and Substances must combine in specific proportions.
