Answer:

2, 2, 1

Explanation:

The coefficient of H₂O will be 2 because we have 2 oxygens on the right side but only one on the left side. Now, we have 4 hydrogens on the left side but only 2 on the right side. To balance, we'll add a 2 as the coefficient of H₂. We don't need to change the coefficient of O₂ because the equation is already balanced.

Final answer, 2, 2, 1.

Juliette [100K]

Answer:

2 Transfer; very different

Explanation:

Ionic compound are compound that are formed from transfer of electron. The cations donate the electron(s) while the anion receive the electron(s). The compound possess a positively charged end and a negatively charge end. Example of ionic compound is NaCl . The sodium donates one electron to the chlorine  to fulfill the octet rule. The sodium atom becomes positively charged  as it donate electron to the chlorine atom. The chlorine atom becomes negatively charged as it receive electron from Sodium atom.

The atoms that are involve in forming ionic compound have very different electronegativity . Electronegativity  is the measure of the ability of an atom to attract a bond pair of electron. For example the NaCl compound, the two atom has verse differences in the electronegativity. Cl atom is far more electronegative than Sodium atom.
