<span>In beta minus (β−) decay, a neutron is converted to a proton and the process creates an electron and an electron antineutrino; while in beta plus (β+) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β+ decayis also known as positron emission.</span>
Answer
Depends on type of mixture. But I think separating the different sized particles through filtration would be a sufficient answer for middle school level unless they have taught you about other mixtures.
Explanation:
Hey,
There are thousands of way to separate mixtures. Each way is specific to the type of mixture. If the mixture is homogeneous processes like distillation can be employed. For heterogeneous mixture filtration can be used to separate particles of different sizes.
Usually, a model is a depiction of a certain entity, never the real thing. In times
past, many, many models look great on paper but are way off!
