The answer is false..............<span>kinetic theory of gases is a topic that can explain many everyday observations. Have you ever wondered why water boils faster at higher altitudes? Or why inflatable pool toys seem flat after sitting in a cold garage? How about why you can smell a candle all throughout the house? All of these phenomena and many more can be explained by the kinetic theory of gases.</span>

A solution contains 35 grams of KNO3 dissolved in 100 grams of water at 40°C. How much more KNO3 would have to be added to make
Marta_Voda [28]

Answer:

32g

Explanation:

potassium nitrate has solubility of about 67g per 100g of water at 40°C, which means that potassium nitrate solution will contain 67g of dissolved salt for every 100g of water.

since at this temperature, our solution contains  35g of potassium nitrate 100g  of water. The solution will be unsaturated because of the less potassium nitrate.

to make saturated solution,

mass of potassuim nitrate = 67g - 35g

= 32g

which means dissolving another  32g  of potassium nitrate in solution at 40 °C will make saturated solution.

How many moles are there in 1.09 kg of Al(OH)3?
alina1380 [7]
  question   1
moles  =  mass/molar  mass  of  Al(OH)3
convert   Kg  to  g
that  is  1.09  x  1000=1090g

moles  is  therefore=1090g/78(molar  mass  of Al(OH)3)=  13.974 moles

   question  2
moles=
2.55g/327.2(molar   mass  of  Pb(CO3)2=  7.79  x   10^-3   moles
from  avogadro  constant
1moles=6.02  x10^23  formula  units
what  about  7.79  x  10  ^-3
={(7.79  x  10^-3)moles  x ( 6.02  x10^23)} /1  mole=4.69  x10^21  formula  units
