Answer:
Explanation:
The ionic compound CuCl2
is a binary compound called Copper (II) Chloride.
This compound is composed of a metal cation of copper with a charge of Cu+2
and a non-metal chloride ion Cl−1. It takes two Chloride
Cl−1 to balance the Copper
Cu+2
. This makes the formula
CuCl2
The copper is the metal, it is located in the middle section of the periodic table known as transition metals. These metals may have more than one possible ionic charge. Copper can have a +1 charge
Cu+1
or a +2 charge
Cu+2
. The roman numeral in the formula name identifies the charge on the atom.
The Cu+2
ion is referred to as Cupric in a system known as Latin Naming, while the
Cu+1
ion is called Cuprous.
So this compound can be named as Copper (II) Chloride or Cupric Chloride.
whole-number ratio of elements in a compound. formula. For example, a compound that has an empirical formula of CH2O may have a molecular formula of C2H4O2, C3H6O3, C4H8O4
The molar mass of CuCl2 is 134.45 g/mol; therefore, you divide 2.5 g of CuCl2 by 134.45 g of CuCl2 leaving you with 0.019 moles
The answer to question 1 is B and to question 2 is A
An ionic bond occurs when an atom transfers or takes Electrons from another atom.
