Answer:

a. have their particles arranged

Explanation:

<em>A crystalline solid is a solid material with a regular (crystal lattice) or irregular (amorphous) ordered array of its components,</em> being these molecules, atoms or ions. These arrengements are held in place thanks to the atraction between components, they can be ionic compounds held by their charges, metal cations surrounded by a sea of electrons, covalent networks with their atoms covalently bonded or molecular crystals held together by weak intermolecular forces.

I hope you find this information useful and interesting! Good luck!

You are running a lemonade stand with your friend. You prepared 10 liters of 0.7 molarity lemonade, but your friend did online r
mr Goodwill [35]

Answer:

add 7.5L of water

Explanation:

M1×V1=M2×V2

M is molarity, V is volume

0.7 × 10 = 0.4 × V2

V2= 17.5L

vol. of water to add= 17.5 - 10 = 7.5L

Lewis structure for nitrogen triiodide, NI(3)
Rasek [7]

Answer:

Lewis structure for nitrogen triiodide,NI_3 is given in the attachment.

Explanation:

Given:

The given compound is Nitrogen triiodide. In which 1 atom of Nitrogen combines with 3 atoms of Iodine. Both Nitrogen and Iodine are non-metals,So they form covalent bond by sharing of electrons.

The electron configuration of Nitrogen and Iodine is given below;

N(7) = 1s^2,2s^22p^3\\I(53) = 1s^2,2s^22p^6,3s^23p^63d^{10},4s^24p^64d^{10},5s^25p^5

There are 5 electrons in valance shell of Nitrogen atom and 7 electrons in valance shell of Iodine atom.

So, 3 atom of Iodine shares 1 electron with 1 electrons of Nitrogen.

The Lewis dot Structure is in the attachment.

David is making lemonade he asked you could you some lemon juice and water the sugar starts to dissolve what can we do to speed
suter [353]

We could (a) stir faster and (b) warm the mixture.

<em>Stirring faster</em> moves freshly-dissolved sugar away from the solid and allows new water molecules to contact with the surface,

<em>Warming the mixture</em> gives the water molecules more kinetic energy, so their collisions with the surface of the sugar will be more effective in removing the sugar molecules.

Fossil originally has 254 g of carbon-14 but currently has 127 g of carbon-14 the fossil is most likely
KATRIN_1 [288]

Answer:

The answer to your question is: letter C) 5730

Explanation:

Data

Originally Carbon - 14   254 g

Currently Carbon - 14   127 g

Half-life of Carbon -14 is when half of the original amount of Carbon disintegrates.

Then, if originally there were 254 and now there are 127, only one half life passed.

Half life of carbon -14 is 5730 years old.
