Imagine that you have four food dyes to test, A,B, C, and D. Imagine that you are going to investigate which food dye diffuses the most quickly. Which variables will you keep the same?D, how many times will you carry out the test?Explain why you will repeat the tests. Ow will you know which dye diffuses the most quickly?

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
