Answer:
23 g of Zn will produce 0.352 mole of zinc chloride.
Explanation:
Given data:
mass of Zn = 23 g
Moles of ZnCl = ?
Solution:
Chemical equation:
2Zn + CuCl₂ → 2ZnCl + Cu
Number of moles of Zn:
<em>Number of moles of Zn = mass/ molar mass</em>
Number of moles of Zn = 23 g / 65.38 g/mol
Number of moles of Zn = 0.352 mol
now we will compare the moles of ZnCl with Zn because it is limiting reactant.
Zn : ZnCl
2 : 2
0.352 : 0.352
So 23 g of Zn will produce 0.352 mole of zinc chloride.

Answer : The number of electrons shared between 1 nitrogen atom and 1 carbon atom are, Six.
Explanation :
Covalent bond : Covalent bonds are made by the sharing of valence electrons between the non-metal elements.
One covalent bond is formed by the sharing of two electrons.
In the given structure of compound, one nitrogen atom bonded with one carbon atom by three covalent bonds. That means the number of sharing electrons between the one nitrogen atom and one carbon atom are six.
