<em>I am going to use first-person pronouns for this drop of water</em>
[ Start ] Liquid
I start out as a drop of water among other drops of water in the ocean. I am currently a liquid as I can change shape easily but I do not float up.
[ Middle ] Gas
The sun feels very hot. From the heat I turn into a gas, specifically water vapor, and float up into the sky.
[ Middle x 2 ] Solid
In the sky I meet up with a lot of my past friends. We form a cloud, and as we grow heavier (the more the merrier) we start to fall down. It is extremely cold now, so we fall down as a solid, also known as hail or snow.
[ End ] Liquid
We hit the ocean again as we fall from the sky. I'm so happy to be back home as a water drop again!
Have a nice day! - <u>Please note this is very simplified</u>
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

The correct answer is:
~Difference between atoms and molecules is that when similar atoms combine together in varying numbers, molecules of different properties can be formed.
Hope this helps!!!
This pull holds<span> the sodium atom near the chlorine atom, making a molecule of </span>salt<span> - one of the most stable molecules on Earth. Most of the solid things in the universe - like rocks - use </span>ionic<span> bonds to </span>hold<span> themselves </span>together<span>. That's because those same electric </span>forces<span> affect other nearby molecules of </span>salt<span> as well</span>
Answer: Heterogenous mixtures are the ones in which we can see the different components clearly. Air is considered to be homogenous, because we don't see the different noble gases' particles floating around. Salt water is also homogenous, because salt dissolves almost completely into water, becoming hard to see without the proper equipment salt particles in it. Steel is also homogenous, since the metals that compose it are mixed during the heating. The only heterogenous would be soil, because we can see different particles in it, with different sizes, shapes, colors, etc without having to use special equipment.
Im not sure if this will help but... your subscripts in a balanced equation are used to calculate the molar mass of the compound. And your coefficients are used to get the ratios. so for example we have this balanced equation
Be3N2 + 6H2O= 3Be(OH)2 + 2NH3 and you have to find the molar mass of 6h2o, you need to multiply the subscript by the atomic mass and then add them together to get the overall molar mass. * 2(1.01) + 16.00= 18.02 g/mol
and if a question wants to know the limiting or excess regent you would use the coefficients to find out the ratio between the compounds.
