I need help with Number 63

Answers

Answer 1

Answer: Isotopes are variants of an element which have differing number of neutrons. So, yes, because all of them have the same atomic number, meaning they are all Mg, however they all have differing atomic masses meaning different number of neutrons.

Is the direct transfer of heat between objects that touch. * Conduction radiation or convection

Answers

The answer to this question is conduction!

Conduction is heat shared by two objects touching, an example would be a pot on a hot plate. The heat goes through the burner into the pot!

Conduction process of heat conduction. For example, A cold cast iron skillet is placed onto a stovetop. When the stove is turned on, the skillet becomes very hot due to the conduction of heat from the burner to the skillet.

Help me!!! Several small craters lie in the floor and on the walls of crater 2. Which is older,crater 2 or the smaller craters inside it?

Answers

Well, think of it this way. If you put a big paper circle on the ground, and then you put smaller circles on top of the big circle, which one would have been there longer? The big circle, of course. So the same logic applies here: if the smaller craters had been older than the big crater, then when the big crater was formed, the smaller ones would've been buried. Therefore, crater 2 is older than the smaller craters inside it.
Hope that helped! =)

How are heterogeneous and homogeneous mixtures separated?

Answers

Explanation:

Homogeneous mixture is separated using two stage separation process: mobile stage and stationary stage. The mobile phase are absorbent such as water, chemicals while the stationary stage is the column used for the separation process. The integral method of separation of homogeneous mixtures is called chromatography (analytical or preparative). Other method of separation of homogeneous mixtures is called distillation and it is based on the various boiling points of the component of mixture.

While heterogeneous mixtures are separated based the properties of the components. One method of separation of solids suspended in liquids is simple filtration.

column 1 Atoms
column 2. lons
column 1 Crystalline
column 2 Noncrystalline
column 1. Definite shape
column 2. Definite volume
column 1 Viscous
column 2 Nonviscous

Answers

Answer:

column 1: they are solids that form crystals.

column 2: Are liquid solutions.

Explanation:

Crystals are solids, some of them can have viscosity like glass.

Liquid solutions, are formed by some ions dissolved in water, so they can have a definite volume and could be a liquid that is nonviscous because they are dissolved in water.

How does the chemical structure of a paper towel differ from the potatoes?

Answers

When you pass around the side dishes at this year's Thanksgiving feast, here's one thing to be thankful for: you're eating mashed potatoes instead of mashed paper towels. But if you were chewing on the towels instead of the spuds, would you even know it.

Because a Paper towel is made like a towel, it is manmade. Potatoes are natural things therefore different.
