Answer:

kL, dL, mL, pL

Explanation:

pL stands for picoliters. This is equal to 1 × 10⁻¹² (0.000000000001) liters.

mL stands for milliliters. This is equal to 1 × 10⁻³ (0.001) liters.

dL stands for deciliters. This is equal to 1 × 10⁻¹ (0.1) liters.

kL stands for kiloliters. This is equal to 1 × 10³ (1000) liters.

What makes an ionic difference than a covalent bond

Eva8 [605]

I’m not completely sure what you mean here but if your talking about charges in covalently bonded molecules then here is something:

Charges in covalent bonds are partial because the ions are shared when bonding.

The charges are no longer full and strong they are half charges, they are not as strong.

You might want to just google a little bit. :)

Hope that helps

at a pressure of 101.3 kilopascal and a temperature of 373 K, heat is removed from a sample of water vapor, causing the sample t

Kruka [31]

Answer:

The amount of heat released is 11.3 KJ

Explanation:

H20(g) -> H20(l) + heat

This reaction is changing state from gaseous to liquid without changing the temperature. This heat is know as Latent heat. It is the energy required for a phase change.

Heat released by 5 g of water vapor (Q) = M × L

where M = mass of vapor

L= latent heat

Latent heat can be divide into 2

Latent heat of fusion
Latent heat of vaporization

Since we are change the gaseous state to liquid, we will be working with Latent heat of vaporization which has a value of 22.6 x 10 ∧5 J/kg

(Q) = M × L

= 0.005 x 22.6 x 10 ∧5

= 11300 J

= 11.3 KJ

1 lmole of O2 contains 22.4 litre

therefore 10.2 miles will contain

=10.2*22.4

=228.48 litre

Hence the correct answer is option D
