zhuklara [117]
LiAlH₄ is used as strong reducing agent. The hydride produced acts as a nucleophile and attacks the electrophillic carbon of carbonyl group. In given example two reactions are observed.

Reaction 1:
                 In first step LiAlH₄ when treated with Ester produces corresponding Aldehyde and alcohol.

Reaction 2:
                This aldehyde produced further reacts with LiAlH₄ to give a reduced product (Alcohols). In this case Butanol is produced.

The reaction schemes are shown as felow,

Show the empirical formula manganese fluoride; 59.1% Mn and 40.9% F. Fill in the subscripts on the formula below. Make sure to h
Gre4nikov [31]

Hey there!:

Given % of Mn=59.1% means 59.1 g of Mn present in 100 g of manganese fluoride.

Molar mass of Mn= 54.938 g/mol

Moles of Mn = mass / molar mass

59.1 /54.938 => 1.07 ≈ 1 mol.

and % of F=40.9% means 40.9 g of of F present in 100 g of manganese fluoride.

Molar mass of F=18.998 g/mol

Moles of F :

40.9 / 18.999 => 2.15 mol ≈ 2 mol.

The mole ratio between Mn:F=  1 : 2

Therefore the empirical formula of manganese fluoride:

=> MnF2=Mn1F2

Hope that helps!

Calculate [h+] and [oh−] for a neutral solution at this temperature. express your answers using two significant figures. enter y
taurus [48]
When we have Kw = 1.2x10^-15
and according to Kw formula:
Kw = [OH-] [H+]
by substitution:

1.2x10^-15 = [OH-][H+]
when the solution is neutral that means:
[OH-] = [H+]
∴1.2X10^-15 = X^2
∴X = 3.46 x 10^-8
∴[OH-] = [H+] = 3.46x10^-8
