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 .
It's a chemical change. In synthesis you add compounds which form new ones. This means that it cannot be a physical or phase change because you form something new. Not all synthesis and decomposition reactions use nuclear energy therefore it is a chemical change.
Answer:
yes
Explanation:
a solid melting into a liquid is a kind of a physical change and it definitely alters the appearance of the substance. A liquid evaporating into gas is also an example of a physical change.
