LiAlH4 reagent can reduce aldehydes to primary alcohols, ketones to secondary alcohols, carboxylic acids and esters to primary alcohols, amides and nitriles to amines, epoxides to alcohols and lactones to diols.
LiAlH4 is a powerful reducing agent compared to sodium borohydride, NaBH4, since the Al-H bond is weaker and thus less stable than B-H bond.
Reduction of aldehydes or ketone to primary and secondary alcohols:
Initially, a hydride ion is transferred onto the carbonyl carbon and the oxygen atom coordinates to the remaining aluminum hydride species to furnish an alkoxy tri hydro aluminate ion, which can reduce the next carbonyl molecule. Thus three of the hydride ions are used up in reduction. The reaction will be as follows :
AlH4 + ROR → RHROH
Reduction of amides to amine:
Amides are converted to amines. The LAH reduction mechanism is slightly different from that depicted for esters. In iminium ion is formed during the reaction since nitrogen atom is relatively a good donor than oxygen atom. The reaction will be as follows:
RONR2 + AlH4 → RNR2

The volume of 0.240 M KOH to react completely with 11.4 ml of 0.110 M sulphuric acid is 5.225 ml.
What is molarity?Molarity of a solution is the ratio of the number moles of solutes to the volume of solution in liters. Molarity is most common term used to express the concentration of a solution.
Let the volume and molarity of the titrant be V1 and M1 respectively and the volume of molarity of the analyte be V2 and M2 then,
M1 V1 = M2 V2.
Given volume of H₂SO₄ = 11.4 ml
Molarity = 0.11 M
Molarity of KOH = 0.24 M
volume of KOH = (11.4 ml × 0.11 M) / 0.24 M
= 5.225 ml.
Therefore, the volume of KOH needed for the titration is 5.2 ml.

How much product is formed?
How much excess reagent remains?
(9 pts. total / 2 pts. for equation - 4 pts. for stoich - 2 pts. for limiting reagent - 1 pt. for excess
reagent.)
1. The limiting reagent would be sulfur.
3. The amount of product formed would be 34.4 grams
2. The amount of excess copper that remains would be 24.96 grams.
Sotichiometric problemCopper and sulfur react to form copper (II) sulfide according to the following balanced equation:
[tex]Cu + S -- > CuS[/tex]
From the balanced equation of the reaction, the mole ratio of copper to sulfur is 1:1.
Recall that, mole = mass/molar mass
Mole of 48.2 grams of copper = 48.2/64
= 0.75 mol
Mole of 35.0 grams of sulfur = 35/98
= 0.36 mol
Since the stoichiometric mole ratio is 1:1, it means that sulfur is the limiting reactant or reagent while copper is in excess.
The excess amount of copper would be: 0.75 - 0.36 = 0.39 mol
Mass of 0.39 mol copper = 0.39 x 64 = 24.96 grams
With sulfur being the limiting reactant, the equivalent amount of CuS formed will be 0.36 mol considering that the mole ratio is 1:1.
Mass of 0.36 mol CuS = 0.36 x 95.6
= 34.4 grams.
In other words, the limiting reactant is sulfur, the amount of product formed is 34.4 grams, and the amount of excess copper is 24.96 grams.

what is the shortest wavelength line in nanometers in series of the hydrogen spectrum when m=l and n>l? (c=1.097*10^7)
91.2 nm is the shortest wavelength line in nanometers in series of the hydrogen spectrum when m=l and n>l
What is hydrogen spectrum?The electromagnetic radiation that a hydrogen electron emits when it transitions from an excited state to a normal state is known as the hydrogen spectrum. The wavelength of the hydrogen spectrum correlates to the energy emitted.
In order to boost electrons to higher energy levels, hydrogen molecules must first be broken into hydrogen atoms (thus the atomic hydrogen emission spectrum). Assume an electron is stimulated to the third energy level. It would probably lose energy once again if it dropped to a lower level.
As we know,
1/λ = R × (z)²× [(1/n₁)² - (1/n₂)²]
Given, it is hydrogen spectrum thus z = 1
and R = 1.097 × 10⁷ m⁻¹
n₁ = 1 and n₂ = ∞
Now,
or, 1/λ = (1.097 × 10⁷ m⁻¹) × (1)²× [(1/1)² - (1/∞)²]

what is the mathematical relation between meter and feet?
The mathematical relationship between meters and feet is based on the conversion factor between these units. The conversion factor is defined as the number of feet per meter, which is approximately 3.2808 feet/meter.
This conversion factor can be used to convert meters to feet by multiplying the number of meters by the conversion factor.
It's important to note that the conversion factor is an approximation, as the exact conversion factor between meters and feet depends on the definition of the meter and the foot. The conversion factor provided here is based on the International System of Units (SI) definitions of these units.
According to the problem:
To convert meters to feet, use the conversion factor 1 meter = 3.2808 feet. To find the equivalent value in feet, multiply the number of meters by the conversion factor.
To convert 400 meters to feet, multiply 400 by 3.2808 to get the following result:

According the Royal Society of Chemistry, your diet's protein-containing foods are where you get your nitrogen. Meat, fish, beans, nuts, eggs, milk, and other dairy items are some of these foods. Nitrogen exposure is hazardous because it can displace oxygen and induce asphyxia.
Briefing:The formula below is used to determine the pressure at a given temperature for a given volume of nitrogen gas:
P₁/T₁ = P₂/T₂
where;
Initial pressure is P1.
Initial temperature is T1.
Final pressure is P2.
T2 is the final temperature.
P2 solution
P₂ = P₁ * T₂ / T₁
P₂ = 0.836 * (680 + 273) / (20 + 273)
P₂ = 2.72 atm =3atm
