Hello, Could someone please give me a basic understanding of these prompts for me to build upon for my chemistry test out 1. Cite evidence for how we know that matter contains positive and negative charges

2.Cite evidence for how we know that negative charges are able to move in a substance

3. Describe how the moving of charges can result in either positive or negative ions

4. Cite evidence for how we know that ionic substances dissociate in water and molecular substances to not.

5. Given a chemical formula, be able to determine whether it would dissociate into ions when dissolved

6. Be able to distinguish between metals and non-metals based on their properties and position on the periodic table.

7.Given the formula of an ionic or molecular substance, state its name

8.Given the name of an ionic or molecular substance, determine its formula.

9.Be able to distinguish how molecular and ionic substances differ on the atomic level.

10.Based on particle arrangement, be able to determine molecular and ionic formulas.

Type the letter that represents the correct location for each particle type below.

What is the molar mass of ca(cio4)2

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
