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.
Step one write the equation for dissociation of AgNO3 and NaCl
that is AgNO3-------> Ag+ + NO3-
NaCl--------> Na+ + Cl-
then find the number of moles of each compound
that is for AgNO3 = ( 1.4 x10^-3 ) x 25/1000= 3.5 x10^-5 moles
Nacl= (7.5 x10^-4)x 60/1000= 4.5 x10^-5 moles
from mole ratio the moles of Ag+= 3.5 x10^-5 moles and that of Cl-= 4.5 x10^-4 moles
then find the total volume of the mixture
that is 25ml + 60 Ml =85ml = 0.085 liters
The Ksp of Agcl = (Ag+) (cl-), let the concentration of Ag+ be represented by x and also the concentration be represented by x
ksp (1.8 x10^-10) is therefore= x^2
find the square root x=1.342 x10^-5
Ag+ in final mixture is = moles of Ag+/total volume - x
that is {(3.5 x10^-5)/0.085} - 1.342 x10^-5=3.98x10^-4
Cl- in the final mixture is =(4.5 x10^-5 /0.085) - 1.342 x10^-5= 5.16 x10^-4

Answer:
Sulfur Dioxide
Explanation:
Sulfur dioxide is the chemical that, when released by factories using fossil fuels, combines with the atmosphere and can produce acid raid.
Answer:
-3
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Protons have a positive (+) charge
- Neutrons have a neutral (0) charge
- Electrons have a negative (-) charge
Explanation:
<u>Step 1: Define</u>
7 protons, 9 neutrons, 10 electrons.
+7, +0, -10
<u>Step 2: FInd charge</u>
7 + 0 - 10 = -3
