You make a solution that has 30 molecules of sugar, 5 molecules of salt and 65 molecules of water.
a. What is the sugar concentration (in %)? B. What is the total solute concentration (in %)? C. What is the water/solvent concentration (in %)?

it's all four options.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

football

explanation:

because it is

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
