Answer:

1 mole of any material contains 6.023×1023 elementary particles. Hence, by ratio and proportion, 5.61mol of diatomic hydrogen gas contains 5.61×6.023×1023 hydrogen molecules =3.3789×1024 H2 molecules.

aalyn [17]

Answer:

If it loses to electrons the net charge will be +2. If the atom instead gains 4 electrons, the net charge will be -4.

Explanation: When an atom loses electrons( which are negatively charged), it turns into a cation. This means since there is more protons(which are positively charged) than electrons, the charge is positive. The charge is positive and than the number of electrons lost. It is the exact opposite for gaining electrons.
