When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling of liquid will begin.

<h3>What happens when atmospheric pressure is equal to the vapor pressure of liquid?</h3>

When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin. The bubbles formation started to the liquid molecules which have gained enough energy to change to the gaseous phase.

The vapor pressure of ethanol is 5.95 kPa at 20.0 °C, and its vapor pressure is 53.3 kPa at 63.5 °C.

Afina-wow [57]

It will take less 1.8 seconds for the mass of a sample of magnesium-20 to decay from 65.6 micrograms to 8.20 micrograms.

<h3>What is Half-Life of radioactive a radioactive substance?</h3>

The half-life of a radioactive element is the time for half the amount of a sample of the substance to decay.

After 0.6 seconds 31.25 remains

After 1.2 seconds, 15.625 remains

After 1.8 seconds, 7.9 micrograms remains.

In conclusion, it will take less 1.8 seconds for the sample to decay to 8.20 micrograms.

Phosphorus-32 has a half-life of 14.0 days. Starting with 4.00 g of 32P, how many grams will remain after 84.0 days ?

Lelu [443]

T₁=84 d
t₂=14 d
m₁=4 g

n=t₁/t₂
n=84/14=6

m₂=m₁/2ⁿ

m₂=4/(2⁶)=0.0625 g

0.0625 grams will remain after 84.0 days

Which product in the reaction forms a precipitate? KNO3 AgCl AgK no precipitate formed.

bija089 [108]

The precipitate formed in the reaction has been AgCl. Hence, option B is correct.

The precipitate has been the solid insoluble substance that has been formed as the product in the double displacement reaction.

The precipitate settles down in the aqueous reaction mixture and are resulted from the double displacement reaction.

<h3>Which one is the precipitate?</h3>

The reaction of silver nitrate and KCl has been:

$\rm AgNO_3\;+\;KCl\;\rightarrow\;AgCl\;+\;KNO_3$

The reactants in the reaction are in the aqueous form. Thus, silver nitrate and KCl are aqueous.

The potassium nitrate has been an aqueous solution, while the silver chloride has been the solid product that precipitates out.

$\rm AgNO_3\;(aq)\;+\;KCl\;(aq)\rightarrow\;AgCl\;(\downarrow)+\;KNO_3\;(aq)$

Thus, the precipitate formed in the reaction has been AgCl. Hence, option B is correct.
