CaC2

Ca - Group 2 metal
C - Group 4 non-metal

It is an ionic compound. :)

Explanation: Ionic compounds has a giant lattice structure with strong electrostatic forces of attraction between ions of Metal and Non-Metal. This compound require a large amount of energy/heat to overcome.

Covalent compounds has a simple molecular structure with weak intermolecular bonds with Non-metals only. This compound requires little energy/heat to overcome.

Answer:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

The cations and anions being oppositely charged attract each other through strong coloumbic forces and form an ionic bond.

How many moles of sodium hydroxide are there in 1.0mL of 2.0M NaOH

kvasek [131]

To find the moles, you can use the following formula

moles= Molarity x Liters

Molarity= 2.0 M
Liters= 0.0010 Liters ---------------->>>>>>>>>> 1.0 mL= 0.0010 Liters

moles= 2.0 M x 0.0010 Liters= 0.0020 moles
