a because it was a combination of lots of subtances like CO2, oxygen, nitrogen,... and u cant see air so it is a homogenous mixture

I came up with a required balloon volume of 476 before adding the extra 1 mL.
Atomic radius decreases along the period due to shielding effect 'cause of addition of electrons in the same shell
Atomic radius increases down the group, due to addition of shell at each successive steps
Hope this helps!
Answer:
This question is asking to calculate the molarity of the solution based on the information provided.
The answer is 2.94M
Explanation:
Molarity of Ca(OH)2 solution = number of moles (n) ÷ volume (V)
Using the formula below to calculate number of moles of Ca(OH)2.
mole = mass/molar mass
Molar mass of Ca(OH)2 = 74 g/mol
mole = 74g/74g/mol
mole = 1mol
Volume of Ca(OH)2 solution = 340ml = 340/1000 = 0.340 L
Molarity = 1/0.340
Molarity = 2.94M
