classification of structures

Question 1

what is a giant ionic lattice

Answer 1

sodium chloride (salt)

Question 2

of is giant ionic lattice made of

Answer 2

positive sodium ions and negative chloride ions and is held together by very strong ionic bonds

Question 3

whats the properties of ionic compounds

Answer 3

high MP and BP - a lot of energy is needed to break the ionic bonds
solubility - soluble in water
electrical conductivity - will not conduct when solid,, will conduct when
molten or dissolved in water

Question 4

whats the examples of molecular covalant structures

Answer 4

oxygen ammonia water

Question 5

explain the molecular covalent structures

Answer 5

the covalent bond is strong but the forces holding them together are very weak (waals forces)

Question 6

whats the properites of molecular covalent structures

Answer 6

very low MP and BP - little energy is needed to break waal force
poor conductor - no charged particles to move and carry the charge
not soluble in water

Question 7

whats the observations for a positive test on chlorine

Answer 7

turns red then bleaches aka turns to white
