Advantages of reduction reaction

Answer»

Advantages: Redox reactions are vital for biochemical reactions. For example: redox reactions in human body include the electron transfer system in cells and oxidation of glucose. Various CHEMICAL substances are PRODUCED with the help of redox reactions which are useful in industrial processes
Oxidation-reduction (redox) reactions are important because they are the principal sources of energy on this planet, both natural or biological and artificial. Oxidation of MOLECULES by REMOVAL of hydrogen or COMBINATION with oxygen normally liberates large quantities of energy.

What kind of solids can be purified by process of sublimation

Answer»

Sublimation is a technique used by chemists to purify compounds. A solid is typically PLACED in a sublimation apparatus and HEATED under vacuum. Under this reduced pressure, the solid volatilizes and CONDENSES as a purified compound on a COOLED surface (cold finger), leaving a non-volatile residue of IMPURITIES behind.

Number of oxygen atoms in 8 gram of ozone is

Answer»

Molar mass of ozone is O3(16*3)=48 grams

No. Of moles of ozone in 8 gram of it =8/48 moles

So no.of moles of O is 3 times no. Of moles of O3 because each ozone MOLECULES CONTAINS 3 atoms of O

N=3*8/48=0.5 moles

So no.of atoms can be calculated by multiplying no. Of moles by AVOGADRO number as

0.5* 6.023×10^23=3.0115×10^23 atoms.

Hope it helps…

We want to prepare dilute sulphuric acid from concentrated acid how will you do it

Answer»

Slowly and carefully add the concentrated sulfuric ACID to clean water, tweak their volumes to obtain the specific concentration of sulfuric acid that you desire.

Equal moles of h2o and nacl are present in a solution hence molality of nacl solution is

Answer»

Consider ‘Y’ mol of water and ‘Y’ mol of NACL are mixed to prepare a SOLUTION.

1 mol of water contains 18 g

That means, Y mol of water contains 18Y g

Mass / Density = Volume

Density of water = 1

So, volume of Y mol water = 18Y / 1 = 18Y mL

That means Y mol of NaCl is dissolved in 18Y mL of water.

1 mol of NaCl contains 58.44 g

That means, Y mol of NaCl contains 58.44Y g

Molality can be CALCULATED as follows:

Molality = (weight of NaCl x 1000) / (Equivalent weight of NaCl x volume of water)

Substitute in EQUATION,

Molality = (58.44Y x 1000) / (58.44 x 18Y)

Molality = 55.56 M

Molality of NaCl solution is 55.56 M.
