Answer:
because of the dry season
Explanation:
the water evaporate from the ground which is taken by the sun for the process of rainfall
Answer:
it will attract an object that has a negative charge
Answer: (a) cesium and bromine :
(b) sulfur and barium: 
(c) calcium and fluorine :
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 nomenclature of ionic compounds is given by:
1. Positive is written first.
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
(a) cesium and bromine: Here cesium is having an oxidation state of +1 called as
cation and bromine
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
called as cesium bromide.
(b) sulfur and barium : Here barium is having an oxidation state of +2 called as
cation and sulphur
is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
. called as barium sulfide.
(c) calcium and fluorine: Here calcium is having an oxidation state of +2 called as
cation and fluorine
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
. called as calcium fluoride.
Answer:
sp2 hybridization
Explanation:
The central carbon in the carbonate ion, CO32-, has sp2 hybridization. Carbonate has a central carbon atom bonded to three oxygen atoms.
