Answer:
Listed below
Explanation:
Analytical chemistry: using quality and quantity observations to identify and measure physical and chemical properties of substances.EXAMPLE: medical diagnosis
Physical chemistry: Combination of physics and chemistry. EXAMPLE:nitric acid eating through wood.
Organic chemistry: Studying of compounds containing carbon in them. EXAMPLE: there are different products that make use of this type of chemistry for example perfumes,gasoline and many more.
Inorganic chemistry: Studies materials without carbon i them. EXAMPLE: Metals AND Gases.
Biochemistry: studies chemical processes occurring in living organisms. EXAMPLE: Human bodies and muscles
Theoretical chemistry: provides explanations to chemical and physical observation. EXAMPLE: Concepts of chemical reactions

Molar mass neon = <span>20.1797 g/mol
20.1797 g ---------- 6.02x10</span>²³ atoms
? g ------------ 3.0 x 10²³ atoms
mass = 3.0 x 10²³ * <span>20.1797 / 6.02 x 10</span>²³
mass = 6.054x10²⁴ / 6.02 x 10²³
mass = 10.05 g

Explanation:
Mole ratio of NaOH to H2O = 2 : 1
Moles of H2O = 1.85mol * (1/2) = 0.925mol.
Mass of H2O = 0.925mol * (18g/mol) = 16.65g.
Answer:
I2 + 2S2O3^2- --------> S4O6^2- + 2I^-
Explanation:
The correct equation is;
2Na2S2O3 + I2 → Na2S4O6 + 2NaI
Oxidation half equation;
2S2O3^2- --------> S4O6^2- + 2e-
Reduction half equation;
I2 + 2e ----------> 2I^-
Overall balanced redox reaction equation;
I2 + 2S2O3^2- --------> S4O6^2- + 2I^-
