Answer:
The molar solubility of carbon dioxide gas is 
.
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:
where,
= Henry's constant = 
= partial pressure of carbonated drink
where = p = Total pressure = 0.400 atm
= mole fraction of 
Putting values in above equation, we get:
Hence, the molar solubility of carbon dioxide gas is .
Answer:
A
Explanation:
Lanthanides share the following common properties: Silvery-white metals that tarnish when exposed to air, forming their oxides. Relatively soft metals. Hardness increases somewhat with higher atomic number.
I think its because its more accurate because it shows you the numbers rather than you reading the approximate temperature on a liquid thermometer
Answer:
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
