How can liquids be seperated by density a the liquids are absorbed onto a paper b the liquids are turned into seperate vapors c the liquids are collected as they evaporate d the liquids are allowed to seperate into layers

D. The liquids are allowed to separate into layers.

Density refers to the weight of the substance. The substance which is light in weight remains at the top of the substance which is heavy or with more density. This principle is used for separation of liquid based on their density.

In the process, the liquid sample composed of various liquids of varying density is poured in a separating funnel. The setup is left as it is without disturbance for considerable period of time. Based upon the weight of the liquid it forms a layer in which liquid with high density settles at the bottom, whereas liquid with less density remain at the top.

the answer is alpha particles hope i you

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
