You are given a mixture consisting of marbles, iron filings, sugar and sand. Suggest a series of steps for separating this mixture. You may make a flowchart, but be careful to fully explain each step (Why are you using that method?). When you are finished, you should have each component of the mixture in a separate beaker.

Explanation:

Start by sifting the marbles out bc they are bigger they will sit in a big sifter

Than with a magnet roll it in what’s left this will pick up all the iron pieces

Than Fill with water and stir this should resolve the sugar which after you sift out the sand you can heat and scrape off beaker and than for a very short time heat up the sand to dry it and not have extra weight from the water

!!!sand only for a few seconds or else it will fly everywhere and if it gets in eye it will sting badly

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
