Answer: +2
Explanation: Formula of oxide is MgO, because oxidation state of Mg in MgCO3 is +2.
The decomposition of water<span> turns into hydrogen and oxygen with electricity causing a chemical change to happen. </span>
Answer:
Charge-charge interactions (salt bridge, ionic bond) are electrostatic interactions between a pair of ions is True.
Explanation:
Electrostatic interaction between pairs of ions involves the transfer of ion/charges from two bonding elements in their ionic state
<span>The correct formula for Beryllium phosphate is Be3(PO4)2
Beryllium has a charge of +2 and phosphate has a charge of -3. So to make the charge equal to zero, 3x +2 = 6, and 2 x-3 = -6
-6 + +6 = 0</span>
Answer:
(NH4)2S(aq) + Pb(NO3)2(aq) --> 2NH4NO3 (aq) + PbS (s)
