Organic Chemistry- The study of most carbon containing compounds.
Inorganic Chemistry- The study of non-organic substances, many of which have organic fragments bonded with metals.
Physical Chemistry- The study of the properties and changes of matter and their relation to energy.
Analytical Chemistry- The intensification of the components and composition of materials.
Biochemistry- The study of substances and processes occurring in living things.
Theoretical Chemistry- The use of math and computers to understand the principles being observed and chemical behavior.

Hi there!

The 6 branches of chemistry are Organic Chemistry, Inorganic Chemistry, Analytical Chemistry, Physical Chemistry, Biochemistry, and Nuclear Chemistry.

Organic Chemistry: The branch of chemistry dedicated to carbon compounds and substances.

Inorganic Chemistry: The branch of chemistry dedicated to non-carbon compounds and substances.

Analytical Chemistry: The branch of chemistry dedicated to identifying and quantifying matter through a variety of different instruments, tools, and practices.

Physical Chemistry: The branch of chemistry dedicated to analysis of chemical phenomena as well as their different behavior and phenomena.

Biochemistry: The branch of chemistry dedicated to the chemical processes such as cellular respiration that occur within living organisms.

Nuclear chemistry: The branch of chemistry dedicated to nuclear processes and properties as well radioactivity.

2. Classify the following solutions as acidic, basic, or neutral at 25OC.

PilotLPTM [1.2K]

Answer: a) pH = 13.00 : basic

b) $[H_3O^+]=1.0\times 10^{-12}$ : basic

c) pOH = 5.00 : basic

d) $[OH^-]=1.0\times 10^{-9}$ : acidic

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

$pH=-\log [H_3O^+]$

Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.

a) pH = 13.00

As pH is more than 7, the solution is basic.

b) $[H_3O^+]=1.0\times 10^{-12}$

Putting in the values:

$pH=-\log[1.0\times 10^{-12}]$

$pH=12$

As pH is more than 7, the solution is basic.

c) pOH = 5.00

$pH+pOH=14.0$

$pH=14.0-5.00=9.00$

As pH is more than 7, the solution is basic.

d) $[OH^-]=1.0\times 10^{-9}$

Putting in the values:

$pOH=-\log[1.0\times 10^{-9}]$

$pOH=9.00$

$pH+pOH=14.0$

$pH=14.0-9.00=5.00$

As pH is less than 7, the solution is acidic.

50.0 g of NaNO3 are dissolved into enough water to make 250 mL of solution. What is the molarity of this solution?

d1i1m1o1n [39]

Answer:

2.35 M

Explanation:

Molarity is mol/L of solution. We have to convert the g to mol and the mL to L. G to mol uses the molar mass of the compound. The molar mass of NaNO₃ is 85.00g/mol.

$50.0gNaNO3*\frac{1molNaNO3}{85.00gNaNO3} = 0.588molNaNO3$

Then you have to convert mL to L.

$250mL*\frac{1L}{1000mL} = 0.250L$

Now divide the mol by the L.

$\frac{0.588mol NaNO3}{0.250L} = 2.352 M$

Round to the smallest number of significant figures = 2.35M
