When a non metal gains or share by two electrons then the valency will be 2^- or 2^+

As electrons are negatively charged particles, if it loses 2 electrons, there will be more protons than electrons by 2, therefore the valency will be 2+. If it gains 2 electrons, there will be more electrons than protons by 2, therefore the valency in this case will be 2-.

Tonya had a mixture of sand, salt, iron particles, and pebbles. What processes should be used to separate the substances in the
marusya05 [52]

Explanation:

Put the pan into a water-containing dish and mix well. Now use a strainer to transfer the solution into another jar. The salt should disappear in it. 

And using a tube with a filtrate, transfer the salts that has sand into another bottle with a filtrate. Therefore the sand is split. Eventually, when all the water vaporizes and the salt stays in the bottle, leave the extra solvent and heat it.

Does the volume of particles affect the behavior of gas
lilavasa [31]

Answer:

Yes, it does, although only physically and not chemically.

Explanation:

If a volume of gas is way spread out, it won't collide with the other gas particles as often, reducing pressure and temperature because they lose kinetic energy to their surroundings when they don't collide.

If it is compressed, it increases temperature and pressure because the gas particles collide with each other and the walls of the container way more often than if they had more space.

Hope this answers your question.

P.S.

Fun fact, gas particles are actually moving at 300-400 meters per second at room temperature, they only slow down to walking speed at very low temperatures, like 10 Kelvin

Which factor has the greatest effect on the melting point of a crystalline solid
slava [35]
Inter-molecular forces. The greater the attraction between particles the more energy required to break the forces or "melt" them.

A line is perpendicular to<br> y = -3x – 9<br> What is the slope of this<br> perpendicular line?
Gwar [14]

Answer:

a. 1/3

In the picture- D. 4

Explanation:

The product of the gradients of perpendicular lines =-1

m1m2=-1

Given an equation of a line in the form y=mx+c, m is the gradient of the line.

For y= -3x-9, m=-3

m1m2=-1

-3×m2=-1

m2=1/3

The gradient of the perpendicular line is 1/3

For the question in the picture, y=-1/4x-9, m=-1/4

m1×m2=-1

-1/4m2=-1

m2=4

The slope of the line perpendicular to y=-1/4x-9 is 4
