The molar mass of vitamin if it contains 4.34% of cobalt is 1358 g/mole.
How is molar mass calculated?
Molar mass is the mass of 1 mole of the compound.One mole of compound contains Avogadro's number of molecules.So,molar mass is mass of Avogadro's number of molecules.
Molar mass is also defined as mass of the sample divided by the amount of substance, measured in moles .It is a bulk quantity not a molecular property of substance. The SI unit of molar mass is kilogram per mole.
In this problem,vitamin has 1 cobalt atom .The atomic mass of cobalt is 58.93 g/mole.So according to the definition,mass of 1 mole of cobalt is 58.93 g =4.34% mass of 1 mole of vitamin.
To find 100% mass of 1 mole of vitamin
58.93/4.43×100=1358 g
Hence,the molar mass of vitamin is 1358 g.

3-hydroxybutanal can exist in equilibrium as a cyclic hemiacetal.true /false
It is false that 3-hydroxybutanal can exist in equilibrium as a cyclic hemiacetal.
Hemiacetal is produced when one molecule of aldehyde and one molecule of alcohol react.
3-hydroxybutanal (see the structure in the picture below) has both carbonyl and hydroxyl group, so it can, theoretically, undergo an intramolecular reaction to form a cyclic hemiacetal in aquatic solution.
Stability of cyclic hemiacetals depends on the size of the ring. Five or six membered rings are generally favored.
If 3-hydroxybutanal form a cyclic hemiacetal, it will have four membered ring, so it will be very unstable. It cannot exist in aquatic solution, while 4-hydroxybutanal can (see the picture below).

Sn2 is a single-step mechanism in which the bond is broken by the attacking nucleophile from the back of the carbon atom. Two reactants are involved in this reaction.
In this mechanism, The nucleophile approaches the substrate at 180° to the carbon leaving group. The carbon-nucleophile bond is formed and the carbon leaving group breaks.
The nucleophile can attack at the same side where the leaving group is present or the nucleophile can attack from the opposite side of the carbon atom. Since complete inversion of configuration is required, so it is compulsory for the nucleophile to attach from the opposite side.

Calculate the ratio (lb-mole o2 react/lb-mole no formed). if ammonia is fed to a continuous reactor at a rate of 100.0 kmol nh3/h, what oxygen feed rate (kmol/h) would correspond to 40.0xcess o2?
if ammonia is fed to a continuous reactor at a rate of 100.0 kmol nh3/h
175 Kmol/h is oxygen the fed rate that corresponds to 40% excess O₂.
Given chemical reaction is
4NH₃ + 5O₂ → 4NO + 6H₂O
The molecular weight of NH₃ is 17.03, O₂ is 32, NO is 30, and, H₂O is 18.
To find the ratio,
Ratio = lb-mole O₂ react / lb-mole NO formed
Or, ratio = 5/4
Or, ratio = 1.25
NH₃ fed rate = 100 Kmol/h
We have to find out whether the Oxygen fed rate corresponds to 40% excess O₂.
For each 4 Kmol of NH₃, 5 Kmol of O₂ is required.
4 Kmol of NH₃ ≡ 5 Kmol of O₂
100 Kmol of NH₃ ≡ 125 Kmol of O₂
So, 125 Kmol of O₂ is required for 100 Kmol of NH₃.
For 40% excess of O₂, the required Kmol is = 125 + 125 × 40%
The required Kmol of oxygen is 175 Kmol/h for excess of O₂.

This type of functional group contains only hydrogen and carbon as constituent elements. They are commonly represented with ‘R’. They are also called hydrocarbyl groups. The bonding between the carbon atoms can be single, double, or triple.
When we define a functional group, we imply a group of atoms of the same or different elements forming a chemically-active section of a compound and creating a class of new compounds. In organic chemistry, there are many such functional groups. For example, an alcohol group (-OH) defines a particular set of characteristics of the compounds that have it as a constituent.

Use integrated first order rate law, which give you the concentration of reactant sulfuryl chloride as function of time t:
ln[SO₂Cl₂] = ln[SO₂Cl₂]₀ - k∙t
([SO₂Cl₂]₀ i the initial concentration and k is the rate constant)
=> [SO₂Cl₂] = e^(ln[SO₂Cl₂]₀ - k∙t) = e^(ln[SO₂Cl₂]₀) ∙ e^( - k∙t)
= [SO₂Cl₂]₀ ∙e^( - k∙t)
The decomposition of SO₂Cl₂ follows the reaction equation
SO₂Cl₂ → SO₂ + Cl₂
So per mole of sulfuryl chloride disappeared one mole of sulfur dioxide is formed. Hence the changes in concentrations of these compounds are related as:
-∆[SO₂Cl₂] = ∆{SO₂] <=> [SO₂Cl₂]₀ - [SO₂Cl₂] = [SO₂] - [SO₂]₀
Assuming there was initially no sulfur dioxide you get for its concentration:
[SO₂] = [SO₂Cl₂]₀ - [SO₂Cl₂]
= [SO₂Cl₂]₀ - [SO₂Cl₂]₀ ∙e^( - k∙t)
= [SO₂Cl₂]₀ ∙(1 - e^( - k∙t))

A corrosion protection method may be a technique used to minimize corrosion such as the application of anti-corrosion coating, cathodic protection, or other methods that make metal resistant to corrosion.
Metal corrosion in most situations is usually slowed, managed, or maybe put to a stop utilizing the right techniques.
What does one mean by corrosion?
Corrosion may be a natural process which converts refined metal to their more stable oxide.It is the gradual destruction of materials {usually metals} by chemical reaction with their environment.In the most common use of the world, this suggests electrochemical oxidation of metals in reaction with an oxidant such as oxygen.
