Calculate the solubility of carbon dioxide in water at an atmospheric pressure of 0.400 atm (a typical value at high altitude).A

Bond [772]

Answer:

The molar solubility of carbon dioxide gas is $4.662\times 10^{-6} M$ .

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{CO_2}=K_H\times p_{liquid}$

where,

$K_H$ = Henry's constant = $3.50\times 10^{-2}mol/L.atm$

$p_{CO_2}$ = partial pressure of carbonated drink

$p_{CO_2}=p\times \chi_{CO_2}$

where = p = Total pressure = 0.400 atm

$\chi_{CO_2}$ = mole fraction of $CO_2=3.33\times 10^{-4}$

$p_{CO_2}=0.400 atm\times 3.33\times 10^{-4} =0.0001332 atm$

Putting values in above equation, we get:

$C_{CO_2}=3.5\times 10^{-2}mol/L.atm\times 0.0001332 atm\\\\C_{CO_2}=4.662\times 10^{-6} M$

Hence, the molar solubility of carbon dioxide gas is $4.662\times 10^{-6} M$ .

A scientist wants to predict the effect of rise of global air temperature on sea level around the world which method a controlle

Verizon [17]

A scientific model is a simplified version of some phenomenon that takes place in natural systems. A scientific model can be visual (flow charts), graphical, conceptual, or mathematical. These models are used to make predictions about how a set of conditions would change the present scenario in future. Scientific models can explain how the ongoing changes in the environment can show long term affect on our planet like the climate change. Therefore, a scientific model can be used to explain the phenomena like the effect of global air temperatures on the mean sea level around the world.

Give an example of a time when you would want to increase friction.

Snezhnost [94]

1) you want to increase friction when it gets cold. If you're outside and it's really cold, you're going to rub your hands to warm them up, therefore friction is increasing

I'm not do sure about decreasing.
