Answer:

The particles in a liquid move very quickly due to heat while it is boiling and gradually turns to gas

Answer: The last one I think

Explanation:

Answer:

10623.0

Explanation:

Because 3541 is speed per hour

You need to find 3 hours

so multiply 3541 x 3

3541 x 3 = 10623

Explanation:

Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ionsare free to move from place to place. Ionic compoundscannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Answer:

The pressure of gas in kilopascals is 55.9

Explanation:

variables given :

volume

temperature

moles  

unknown variables :

pressure

Select the correct algebraic form for the equation to be used for this calculation.

p= nRT/V

Solve the problem for the pressure of oxygen.

Answer:

You can see the periodic table one by one.

Pb(NO3)2 = PbN2O6

So there are

1Pb

2N

6O

and so you find the molecular mass from the periodic table and add all the numbers

Molacular mass of

Pb = 207

N = 14

O = 16

multiply it with the number of atoms

1Pb = 207 × 1 = 207

2N = 14 × 2 = 28

6O = 16 × 6 = 96

Molecular mass total = 207 + 28 + 96 = 331

So the molecular mass is 331.

Explanation:

Water can take many forms. At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid. While at temperatures above 100°C, water is a gas (steam).

The state the water is in depends upon the temperature.  Each state (solid, liquid, and gas) has its own unique set of physical properties.

Answer:

5,18*10^{24}

Explanation:

N=8.6*6.02*10^{23}

N=5,18*10^{24}

Answer:

c6h6

Explanation:

Answer:

0.183 mol

Explanation:

so balenced equation is 6Co+4P=2(Co3P2)

so so the ratio is 6:4

so .275/6*4

=0.183 mol I think

The Answer will be:  0.183 mol

       so that .275/6*4

      =0.183 mol.

( 1 CO 2  molecule  ×  2 O atoms CO 2 molecule) + ( 2 H 2 O molecule  × 1 O atom H 2 Molecule  ) = 4 O atoms

Lowering the pressure in a container will cause the liquid in the container to boil faster because it becomes easier for the molecules to escape.

Boiling happens when the vapor pressure of a liquid equals the atmospheric pressure.

By lowering the atmospheric pressure, the vapor pressure of a liquid takes a lower time to equal the atmospheric pressure.

Thus, it becomes easier for the molecules of the liquid to escape from each other.

Answer:

31.0 g C8H18

Explanation:

Gasoline is equivalent to C8H18

to convert molecule to gram you have to convert molecules to mols first.

Using Avocado's number we can figure that out.

(1.63 x 10²³ molecules C8H18) (1 mol C8H18/ 6.022 x 10²³) = 0.271 mols C8H18

Then we convert mols to grams using the molar mass of C8H18

C - 8(12.011) = 96.088 g/mol

H - 18(1.008) = 18.144 g/mol

add that together: 114.232 g/mol

(0.271 mol C8H18) (114.232 g/ 1 mol C8H18) = 31.0 g

31.0 g C8H18

P.S: SORRY IF THIS DOESNT HELP!! I dont know if they are talking about the actual formula for gasoline.

Answer:

Particles?  Calcium hydroxide does not exist as discrete molecules, but as a network solid.  The only way you would have separate particles, is if the calcium hydroxide was dissolved in a boatload of water.  Ca(OH)2 is not all that soluble in water.  Nonetheless, assume a lot of water, enough to dissolve 56.9 moles.

Ca(OH)2 --> Ca2+ + 2OH-

56.9 moles Ca(OH)3 x (3 moles ions / 1 mol Ca(OH)2) = 170.7 mol ions
