Meg used two examples to represent two different states of matter.
torisob [31]

Answer:

c  Example 1 represents a liquid and Example 2 represents a solid.

Explanation:

Example 1: Young children dancing slowly around one another

The young children dancing slowly around one another can be pictured as the flow of liquid. In liquids, the molecules are held about weakly and they slide on top of each other. They are held by weak attractive forces. This is clear picture of a liquid.

Example 2: Newborn babies sitting in their given spots in a crib

This is clear example of a solid. In a solid the molecules are held about a fixed spot. The attractive forces in liquids is very great and the molecules therein do not move about randomly.

Suppose that a newly discovered element called centium has 3 isotopes that occure in nature. These are centium -200, centium -20
vodomira [7]

Answer:

The answer to your question is 203.8 g

Explanation:

Data

Average atomic mass = ?

Centium-200

Centium-203

Centium-209

Equal amounts

Process

1.- Determine the abundance of each isotope.

If they are in equal amounts in nature, just divide 100 by 3

             100/3 = 33.33 % or 0.333

2.- Determine the Average atomic mass

Average atomic mass = Atomic mass 1 x abundance + Atomic mass 2 x

                                        abundance + Atomic mass 3 x abundance

- Substitution

Average atomic mass = 200 x 0.333 + 203 x 0.333 + 209 x 0.333

- Simplification

Average atomic mass = 66.6 + 67.6 + 69.6

Result

Average atomic mass = 203.8 g

18. Sucralose contains which two functional groups: (2 points)
sasho [114]

Answer:

The correct answer is option B and D, that is, halogen (chlorine) and hydroxyl.

Explanation:

An artificial sweetener and sugar substitute is sucralose. It is noncaloric as the majority of the sucralose ingested does not get dissociated within the body. The generation of sucralose takes place by the chlorination of sucrose. It is about 300 to 1000 times sweeter in comparison to sucrose.  

The consumption of sucralose is safe for both nondiabetics and diabetics, it is used in various food and beverage components due to non-caloric sweetener characteristics. It does not affect the levels of insulin and does not affect dental health. As it is produced by chlorination of sucrose, thus, the functional groups present in it are a halogen (chlorine) and a hydroxyl.
