Answer:

Total mass of leaked fluorine in six months= 0.405 kg

Explanation:

From the given,

Leaked mass of freon = 35.12 gm

Molecular mass of freon = C_{2}H_{2}F_{3}Cl = (2\times 12)+(2\times1)+(3\times19)+(1\times35.5)=118.5g/mol

Total weeks per month = 4

Fluorine released into the air in total weeks = 6/times4=24

3 molecules of fluorine is present in the freonC_{2}H_{2}F_{3}Cl

{\tex Mass\,leak\,rate\,of\,fluorine}\,= \frac{Mass\,of\,fluorine\,in\,freon}{Molecularmass\,of\,freon}\times leak\,rate

\frac{19\times 3}{118.5}\times 35.12=16.8gm/week

Total mass of fluorine leaked in six months = 24\times16.9=405.6gm= 0.405 kg

Sati [7]

Put the <em>wood and excess oxygen in a closed contai</em>ner that contains some device that can create a spark (to start the reaction).

Determine the <em>mass of container + contents</em>.

<em>Start the reaction</em> and, after everything has cooled down, again determine the <em>mass of container + contents</em>.

If the two masses are the same, you have demonstrated that the reaction obeys the Law of Conservation of Mass.

Which is a postulate of the kinetic-molecular theory?
oee [108]
An increase in the number of gas particles in the container increases the frequency of collisions with the walls and therefore the pressure of the gas. The last postulate of the kinetic molecular theory states that the average kinetic energy of a gas particle depends only on the temperature of the gas.
