Answer:

$k=1.12x10^{-4}s$

Explanation:

Hello,

By considering the rate law:

$ln(\frac{[CO_2]}{[CO_2]_0} )=-kt\\$

Solving for the time, we've got:

$k=-\frac{ln (\frac{[CO_2]}{[CO_2]_0 })}{t}\\\\k=-\frac{ln(\frac{56.0mmol*dm^{-3} }{220mmol*dm^{-3} })}{1.22x10^{4}s }\\ \\k=1.12x10^{-4}s$

Best regards.

What is the final temperature, in degrees Celsius, of the gas in the bubble outside the volcano if the final volume of the bubbl

lawyer [7]

The question is incomplete, here is the complete question:

A 127 mL bubble of hot gases at 213°C and 1.89 atm is emitted from an active volcano.

What is the final temperature, in degrees Celsius, of the gas in the bubble outside the volcano if the final volume of the bubble is 136 mL and the pressure is 0.850 atm , if the amount of gas does not change?

<u>Answer:</u> The temperature of the gas is -40°C

<u>Explanation:</u>

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.

The equation follows:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1,V_1\text{ and }T_1$ are the initial pressure, volume and temperature of the gas

$P_2,V_2\text{ and }T_2$ are the final pressure, volume and temperature of the gas

We are given:

$P_1=1.89atm\\V_1=127mL\\T_1=213^oC=[213+273]K=484K\\P_2=0.850atm\\V_2=136mL\\T_2=?$

Putting values in above equation, we get:

$\frac{1.89atm\times 127mL}{484K}=\frac{0.850atm\times 136mL}{T_2}\\\\T_2=\frac{0.850\times 136\times 484}{1.89\times 127}=233K$

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

$T(K)=T(^oC)+273$

$233=T(^oC)+273\\\\T(^oC)=-40^oC$

Hence, the temperature of the gas is -40°C

When discussing discordant and harmonious sound waves, which statement is false?

notka56 [123]

When discussing discordant and harmonious sound waves, the statement tat is false is : if the original waves combine to form irregular displacement of air, the sound will be discordant. The fact is, irregular displacement of air does not guarantee sound discordance

can someone please explain me electronic arrangement of different elements please tomorrow is my paper i neEd help ASAP !!!!!!!

NNADVOKAT [17]

Answer:

This list of electron configurations of elements contains all the elements in increasing order of atomic number.

To save room, the configurations are in noble gas shorthand. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. Look up the electronic configuration of that noble gas and include that value before the rest of the configuration.
