How could one rapidly separate red #40 from zinc oxide? indicate every step.

The mixture of Red # 40 and zinc oxide is a heterogeneous mixture which can be separated by filtration

The mixture is a combination of two or more substances whose constituent properties do not change. The properties of the mixture component are not lost / unchanged as in compounds.

The mixture can be divided into a homogeneous mixture if the composition/ratio of each substance in the mixture is the same and heterogeneous mixture if the ratio of the composition of the substances is not the same in each place.

Mixtures can also be divided into solutions, suspensions, and colloids based mainly on the size of the particles

There are various mixed separation techniques including filtration, distillation, evaporation, extraction or chromatography

Red # 40, is an artificial coloring obtained from mixing hydrocarbons and is used in dyes such as candy or drinks

Zinc oxide or ZnO is an inorganic powder form which is used as an additive in the manufacture of products such as ceramics or glass and is not soluble in water but can dissolve in acids or bases

A heterogeneous mixture can be separated through physical separation techniques

The mixture of Red # 40 and zinc oxide is a heterogeneous mixture which can be separated by filtration because

Red # 40 can dissolve in water while zinc oxide is insoluble

Zinc oxide and red # 40 is filtered from the mixture using a filter paper

The filtering results called filtrate will be zinc oxide and the residual filtering called residue is Red # 40

While the separation of red # 40 and zinc oxide from water using evaporation techniques to obtain the dry solids

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

i think that is the right
