Answer:
Agroup one.B group seven. lonic/electrovalent bonding.
sodium chloride, 2,8. 2,8,8
Explanation:
the reason why it is an lonicbonding is because it is a force of attraction between opposite charges.it involves the transfer of electrons from a metal to a non-metal.
Answer:
0.68 V
Explanation:
For anode;
3Mg(s) ---->3Mg^2+(aq) + 6e
For cathode;
2Al^3+(aq) + 6e -----> 2Al(s)
Overall balanced reaction equation;
3Mg(s) + 2Al^3+(aq) ----> 3Mg^2+(aq) + 2Al(s)
Since
E°anode = -2.356 V
E°cathode = -1.676 V
E°cell=-1.676 -(-2.356)
E°cell= 0.68 V
Pressure caused by high temperatures are balanced by gravity
