Answer: In a compound with molecular formula ,the valency of Y and X are 2 and 3 respectively.
Explanation:
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 given compound is where X and Y combine and their oxidation states or valencies are exchanged and written in simplest whole number ratios. Thus the oxidation state or valency of X is 3 and that of Y is 2.
Lewis structures are diagrams that show the bonding between
atoms of molecule and the lone pairs of electrons that may exist in the
molecule. Phosphoryl iodide is used in the preparation of organophosphorus
derivatives and phosphate esters. The Lewis structure of POI3 is:

Explanation:
specific heat of granite s = .79 J / g / k
let the mass of granite = m
heat lost by granite = heat gained by water
heat lost = mass x specific heat x drop in temperature
= m x .79 x (80 - 20.45)
heat gained by water
= 3000 x 4.186 x (20.45- 20)
heat lost by granite = heat gained by water
m x .79 x 59.55 = 3000 x 4.186 x .45
m = 120.12 g .

Explanation:
There are two kinds of mixtures
- Homogeneous is a mixture of two or more elements or compounds and its components can not be distinguished visually.
- Heterogeneous is a mixture of two or more elements or compounds and its components can be distinguished visually.
a cup of tea and sugar homogeneous
peanuts and almonds mixed together in a bowl heterogeneous
a bucket full of sand and gravel heterogeneous
food coloring dissolved in water homogeneous
