The answer is:

glucose, a polar organic compound

silver nitrate, an ionic compound

The two have net charges that enable them to attract with water molecules. Water molecules are partly charged because of the arrangement of electron clouds around the molecule. The oxygen atom in the molecule is more electronegative than the two hydrogens. Therefore water is able to form electrostatic attraction forces with the charged molecules

What are the n, l, and possible ml values for the 2p and 5f sublevels?

elixir [45]

Answer:

1. 2p sublevels, n = 2, orbital p, l = 1, ml = 0, ±1

2. 5f sublevels n = 5, orbital f, l = 3, ml = 0, ±1, ±2, ±3

Explanation:

The rules for electron quantum numbers are:

1. Shell number, 1 ≤ n

2. Subshell number, 0 ≤ l ≤ n − 1

3. Orbital energy shift, -l ≤ ml ≤ l

4. Spin, either -1/2 or +1/2

So,

1. 2p sublevels,

n = 2, orbital p, so l = 1, ml = 0, ±1

2. 5f sublevels

n = 5, orbital f, so l = 3, ml = 0, ±1, ±2, ±3

Elements and compounds are more similar to each other than they are to mixtures because:

Dovator [93]

Answer:

elements and compounds can only be liquids or solids, but mixtures can be solids, liquids or gases

Explanation:

Element: A substance that is made up of only one type of atom. Compound: A substance that is made up of more than one type of atom bonded together. Mixture: A combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.

Based on your knowledge of energy resources conservation, which of the following statements is true? a) Manufacturers can increa

Kruka [31]

Answer: Option (b) is the correct answer.

Explanation:

When useful energy is conserved then this conservation is known as energy conservation.

For example, when lights of a room are switched on where no one is sitting then on switching off the lights we are conserving wastage of electricity.

Thus, we can conclude that out of the given options, the statement energy resources can be conserved by turning off lights when they are not in use is true.

I need help on 4-6 pleasee

GenaCL600 [577]

4. It is an endothermic process. The body of someone taking a shower would be absorbing heat from the environment, another example of this would be cooking an egg

5. Ice melting is endothermic. The ice is absorbing heat from the environment, water freezing would be an exothermic reaction as it is transferring heat into the environment

6 however i do not have an answer for. I may just be a little dense but I'm not entirely sure what it is asking when it asks what the system is.
