Which of the following statements about moles is FALSE? SELECT AN ANSWER

One mole of carbon would contain 6.02 x 1023 carbon atoms, but one mole of chlorine would contain 6.02 x 1023 diatomic chlorine molecules.

For ionic compounds, the representative particle is the formula unit of the compound (eg. NaCl).

One mole of water (H2O) contains 6.02 x 1023 atoms.

Avogadro's number is the number of discrete, representative units found in one mole of a substance.

Option C

Explanation:

Avogadro number represent discrete unit of a substance which can be atom, molecule, ion etc.

In one mole of H2O there will be 6.02 x 1023 molecules and not atoms.

Molecule of H2O is the discrete unit of water mole and not atom.

Hence, option C is correct choice of answer

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the correct answer is:

a. formation of precipitation
