Answer:
Ionic
Explanation:
Any metal with a nonmetal is an ionic bond due to the transfer of electrons.
Answer:
To balance the reaction, we should put a 4 in front of Al
Explanation:
<u>Step 1:</u> Data given
AI+3O2->2AI2O3
<u>Step 2:</u> Balance the equation
On the right side we have 2*3 = 6 oxygen atoms
On the left side we have 3*2 = 6 oxygen atoms as well, so those are on both side balanced
On the right side we have 2*2 = 4 Al atoms
On the left side we have only 1 Al atom
We should multiply this by 4 (place a 4 in front of the Al)
4AI + 3O2 → 2AI2O3
Now al atoms are balanced on both sides.
Valence electrons in metallic bonding occupy whole piece of metal, they do not connected to particular atom,
in ionic they move to more electronegative atom, in covalent bond they between atoms ( covalent polar located closer to more electronegative)
Answer : The number of silver atoms produced will be
Explanation : Given,
Number of atoms of copper =
The given balanced chemical reaction,
From the balanced chemical reaction we conclude that,
As, number of copper atoms react to give number of silver atoms.
So, number of copper atoms react to give number of silver atoms.
Therefore, the number of silver atoms produced will be
