Answer:

And since there is a frictional force acting upon the rotating blades of the fan due to the air, the speed of the fan blades ceases and ultimately comes to halt. Thus here, air friction is the external force which makes the fan blades to stop after sometime, otherwise it would have never stopped rotating :P.

Anuta_ua [19.1K]

dissolves easily in water

has a high boiling point

has a high melting point

conducts electricity when melted

Explanation:

Salts are ionic compounds. Ionic compounds are formed when two atoms exchange their valence electrons. One atom gains and the other atom loses.

Generally, ionic compounds have the following properties:

  1. They are usually hard solids with high melting points or liquids with high boiling points.
  2. They are soluble in water and insoluble in non-polar solvents. This is conforms with the solubility rule that like dissolve like.
  3. In aqueous solution or molten form, ionic compounds conducts electricity.
  4. They take part in very fast chemical reactions.

A sample of gas at 3000.0mmHg inside a steel tank is cooled from 500.0°C to 0.00°C what is the final pressure of the gas in the
Andrej [43]

Answer:

1429.32 mmHg

Explanation:

Initial Pressure P1 = 3000.0mmHg

Initial Temperature T1 = 500.0°C + 273 = 573 K ( Converting to kelvin temperature)

Final Temperature T2 = 0.00°C + 273 = 273 K ( Converting to kelvin temperature)

Final Pressure P2 = ?

The pressure of a given amount of gas is directly proportional to the absolute temperature provided volume remains constant.

This is given by the mathematical expression;

P1 / T1  = P2 / T2

Inserting the values;

3000 / 573 = P2 / 273

P2 = 273 * 3000 / 573

P2 = 1429.32 mmHg

What molarity is prepared when a solution contains 0.277 moles of calcium bromide in 500 mL of solution (must change mL to Liter
Vladimir79 [104]

Answer:

0.554M of Calcium Bromide

Explanation:

Molarity by defintion is #of moles of something/litres of solution.

Therefore, here, we have 0.277 moles of calcium bromide and 500mL (divide 500ml by 1000 to go from mL to L because for every 1L there's 1000mL) or 0.5L.

Molarity= 0.277/0.5 = 0.554M of Calcium Bromide
