Answer:                                                                                                

  1. Definite shape, definite volume, definite melting point, high density,        incompressibility, and low rate of diffusion.
  2. The most obvious physical properties of a liquid are its retention of volume and its conformation to the shape of its container.
  3. When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel.
  4. There are four types of crystalline solids: ionic solids, molecular solids, network covalent solids and metallic solids.
  5. There are two types of liquid-liquid mixtures. They are: Homogeneous Liquid-Liquid Mixture. This is a type of liquid-liquid mixture whereby the two substances mix completely to from a single substance.

Which element has the following electron configuration: <br> 1s22s22p63s23p64s23d104p65s24d105p5
Natasha2012 [34]
Try adding spaces next time! That's iodine. Check all of the numbers to make sure all of the orbitals are filled, then find the ones which aren't. In this one, only the 5p5 subshell isn't full. 5p5 is the fifth row on the right side, count across the nonmetals and metalloids until the fifth one (a halogen). That's iodine, and that's your answer!

What is the volume of 1.56 kg of a compound whose molar mass is 81.86 g/mole and whose density is 41.2 g/ml?
hjlf

Answer:

v = 37.9 ml

Explanation:

Given data:

Mass of compound = 1.56 kg

Density = 41.2 g/ml

Volume of compound = ?

Solution:

First of all we will convert the mass into g.

1.56 ×1000 = 1560 g

Formula:

D=m/v

D= density

m=mass

V=volume

v = m/d

v =  1560 g / 41.2 g/ml

v = 37.9 ml
