0.00010 written in scientific notation is 1.0 * 10^-4.

Scientific notation refer to the standard manner of writing numbers that are too small or that are too big in such a way that it will be convenient to involve them in calculations and also easier to compare them. Another name for scientific notation is standard form. The format of scientific notation is Z * 10^a, where Z can be any number between 1 and 9 and a is an integer, which can be positive or negative. For the number given in the question, the number of zeros at the back of 1 is counted [there are four zeros] and this number is written as an index of 10. A negative sign is added to the number because of the decimal point in the figure.

Write a mechanism (using curved-arrow notation) for the deprotonation of tannins in base. Use Ar-OH as a generic form of a tanni
Reika [66]

Answer:

After deprotonation of tannin, tannin (Ar-OH) is converted to Ar-O^{-}Na^{+} salt which is soluble in water and CO_{3}^{2-} is converted to HCO_{3}^{-}Na^{+} which is also soluble in water

Explanation:

  • Sodium carbonate is a strong electrolyte which produces carbonate anion upon dissociation.
  • Carbonate ion is a strong conjugate base of weak acid HCO_{3}^{-}
  • After deprotonation of tannin, tannin (Ar-OH) is converted to Ar-O^{-}Na^{+} salt which is soluble in water and CO_{3}^{2-} is converted to HCO_{3}^{-}Na^{+} which is also soluble in water
  • Balanced equation: Ar-OH+Na_{2}CO_{3}\rightarrow Ar-O^{-}Na^{+}+Na^{+}HCO_{3}^{-}
  • Mechanism has been shown below.

astra-53 [7]
Secondary Alcohol is converted into corresponding Cyanohydrin in two steps;

Step 1:
           Oxidation of Sec. Alcohol:
                                                    Secondary Alcohols when treated with Sodium Dichromate in acidic medium are converted into corresponding Ketone.

Step 2:
           Reduction of Ketone using HCN:
                                                               Ketone is reduced to Cyaynohydrin when treated with CN nucleophile. A nucleophillic addition reaction takes place.

Suppose you had four spoons the same size and shape made out of glass, plastic, steel, and wood. Which spoon handle would get ho
Burka [1]

Answer:

A. steel spoon

Explanation:

A steel spoon will get hot the quickest from the different given spoon. This is because steel is predominantly made up of a metal which shows metallic properties such as heat conduction.

  • Metals have low specific heat capacity which is the amount of head needed to raise 1g of a substance by 1°C.
  • By so doing, metals will conduct heat at a very fast rate.
  • The delocalized electron around the central nucleus plays very important role.

Other properties originating from metallic bonds are ductility, malleability, luster etc.

Using the same sample of gas (P1 = 565 torr , T1 = 27 ∘C ), we wish to change the pressure to 5650 torr with no accompanying cha
Stels [109]

Answer:

2726.85 °C

Explanation:

Given data:

Initial pressure = 565 torr

Initial temperature = 27°C

Final temperature = ?

Final pressure = 5650 torr

Solution:

Initial temperature = 27°C (27+273 = 300 K)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

T₂  = P₂T₁ /P₁

T₂  = 5650 torr × 300 K / 565 torr

T₂  = 1695000 torr. K /565 torr

T₂ = 3000 K

Kelvin to degree Celsius:

3000 K - 273.15 = 2726.85 °C
