Ionic compounds are formed by the complete transfer of electrons from more electronegative elements to less electronegative elements.
7. <u>Sodium Nitride (Na₃N)</u> is an ionic substance.
8. The ionic formula for <u>Lithium Oxide is Li₂O</u>
9. The <u>compound SrF₂</u>
10. Aluminum Sulfide is a chemical compound with the <u>formula Al₂S₃.</u>
An ionic compound is a chemical compound composed of ions held together via electrostatic forces termed ionic bonding. The compound is neutral standard but includes definitely charged ions known as cations and negatively charged ions known as anions.
An ionic compound is a chemical compound composed of ions held collectively by means of electrostatic forces termed ionic bonding. The compound is neutral normal however consists of positively charged ions known as cations and negatively charged ions referred to as anions. Ionic compounds incorporate ions and are held collectively via the attractive forces of most of the oppositely charged ions.

Answer:
Polar
Explanation:
Methanol is not electrostatic
It's not metallic as it has no metals in it
It's not ionic as coordinate bonding is made.
It's polar as a lone pair is present over OH-
The molecules will be more separated, and will have least amount of intermolecular force of attraction.
<h3><u>Explanation:</u></h3>
The molecules inside the jar of Lilly are moving around each other. This means the state of the matter present inside the jar is liquid. As Lily gives more energy inside the jar , the molecules inside the jar will get more separated as the kinetic energy of the molecules increase and the intermolecular force of attraction decreases as well as the intermolecular separation or distance increase. As the energy is continued to be supplied from outside, there will be a time when this liquid will reaches boiling point and will start to change into gas. After this point the intermolecular force of attraction will be least among molecules and their separation will be maximum.
Answer is: 6,16 kJ.
1) changing temperature of ice from -25°C to 0°C.
Q₁ = m·C·ΔT
Q₁ = 18 g · 2 J/g·°C · 25°C
Q₁ = 900 J.
m(H₂O) = 1mol · 18 g/mol = 18 g.
C - <span>specific heat of ice.
</span>2) changing temperature of water from 0°C to 70°C.
Q₁ = m·C·ΔT
Q₁ = 18 g · 4,18 J/g·°C · 70°C
Q₁ = 5266,8 J.
C - specific heat of water.
Q = Q₁ + Q₂ = 900 J + 5266,8 J
Q = 6166,8 J = 6,16 kJ.
