Answer:

The pressure contribution from the heavy particles is 17.5 atm

Explanation:

According to Dalton's law of partial pressures, if there is a mixture of gases which do not react chemically together, then the total pressure exerted by the mixture is the sum of the partial pressures of the individual gases that make up the mixture.

In the simulation:

the pressure of the 50 light particles alone was determined to be 5.9 atm, the pressure of the 150 heavy particles alone was measured to be 17.5 atm,

the total pressure of the mixture of 150 heavy and 50 light particles was measured to be 23.4 atm

Total pressure = partial pressure of Heavy particles + partial pressure of light particles

23.4 atm = partial pressure of Heavy particles + 5.9 atm

Partial pressure of Heavy particles = (23.4 - 5.9) atm

Partial pressure of Heavy particles = 17.5 atm

Therefore, the pressure contribution from the heavy particles is 17.5 atm

Which action would shift this reaction away from solid calcium fluoride and toward the dissolved ions?a) adding calcium ionsb) a

Mila [183]

Answer:

c) removing fluoride ions.

Explanation:

Hello!

In this case, for this solubility product problem, it is very convenient to write the undergoing ionization reaction:

$CaF_2(s)\rightleftharpoons Ca^{2+}(aq)+2F^-(aq)$

In such a way, via the Le Chatelier's principle, we remember that the addition of reactants shifts the reaction towards products, adding products shifts the reaction towards reactants, removing reactants shifts the reaction towards reactants and removing products shifts the reaction towards products. In means, that the best way to shift this reaction away from solid calcium fluoride and toward the dissolved ions is c) removing fluoride ions, because it is a product and its removal favors the formation of more products.

Best regards!

You go out to dinner and the bill comes to $ 26.37. How much should you tip if you want the tip to be 19.0 % of the bill?

Lerok [7]

If we want to tip 19% or 0.19 of a bill of $26.37

We just multiply 26.37*0.19=$5.01

Any questions please feel free to ask. Thanks

A space probe on the surface of mars sends a radio signal back to earth,a distance of 7.19 ×10⁷ km. Radio travel at the speed of

lys-0071 [83]

Answer:

240 seconds

Explanation:

Data Given:

Distance Radio travel to earth = 7.19 ×10⁷ km

Speed of this radio signal = 3.00 ×10⁸ m/s

Solution:

First convert Km to m

1 km = 1000 m

7.19 ×10⁷ km = 7.19 ×10⁷ x 1000 = 7.19 × 10¹⁰m

Formula used to calculate time

Speed (S) = distance (d) / time (t)

rearrange above equation for time

time (t) = distance (d) / Speed (S) . . . . . . . . .(1)

Put values in equation 1

time (t) = 7.19 × 10¹⁰/ 3.00 ×10⁸ m/s

time (t) = 240 s

So 240 seconds it take for the signal to reach the earth
