Explanation:
electrovalent bond covers single bond.
Covalent bond covers double or more bonds.
Between phosphorous, sulfur, chlorine and argon, argon is the element that's the least likely to form an ionic bond with sodium.
The volume of 0.175 M Na3PO4 solution that is necessary to completely react withn 95.4 ml of 0.102 M cuCl2 is
<u>calculation</u>
<u> </u><em> Step 1: </em> write the equation for reaction
3CuCl2 (aq) + 2Na3Po4 → Cu3(PO4)2 + 6 NaCl
Step 2 : find the moles of CuCl2
moles = molarity x volume in liters
volume in liters = 95.4 /1000 =0.0954 L
moles is therefore = 0.0954 L x 0.102 M= 0.00973 moles
Step : use the mole ratio to calculate the moles of Na3Po4
The mole ratio of CuCl2 : Na3PO4 is 3:2 therefore = 0.00973 x2/3= 0.00649 moles
Step 4 : find the volume of Na3PO4
volume = moles/molarity
= 0.00649 mole / 0.175=0.037 M
Answer: False
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Example: 
has similar molecular formula and empirical formula as the elements are already present in simplest of the ratios.
has molecular formula of but 
as the empirical formula.
