If you have 5.0 mL of an monoprotic acid with an unknown concentration, and it requires 35.25 mL of 0.137M NaOH to reach the equivalence point in a titration, what is the concentration of the acid?

clouds form

solid ice forms on leaves.

water droplets form on grass.

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

they are all solids.

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.
