The other spot that would be assuming all starting material was consumed are drop or splash an organic compound on the plate.

When we pour a petroleum on the solid mixture. It will mixed the biphenyl but not the triphenylmethanol and this causes separation.

The full form of TLC Plate is Thin Layer Chromatography Plates

It is a ready-made plates used which are chemically fixed.

The halted phase is draw on on its surface in the form of a thin layer. The halted phase on the plate has a fine particle size and also has a consistent thickness.

Uses of TLC Plates : for estimating the purity in the chemical formula and for finding compounds.

It is a composition of silica gel with a back support of plastic.

It shows UV absorption.

The volume of a weather balloon is 200.0 L and its internal pressure is 1.17 atm when it is launched at 20 °C. The balloon rises
brilliants [131]

Answer:

2022 L

Explanation:

Ideal gas laws will work for gas in the balloon

The general gas law is for a gas at two arbitrary states 1 and 2 is given by

(P₁ V₁)/T₁ = (P₂ V₂)/T₂

P₁ = 1.17 atm

V₁ = 200.0 L

T₁ = 20°C = 293.15 K

P₂ = 63 mmHg = 0.0829 atm

V₂ = ?

T₂ = 210 K

(1.17 × 200)/293.15 = (0.0829 × V₂)/210

V₂ = (210 × 1.17 × 200)/(293.15 × 0.0829)

V₂ = 2022 L

31. calculate the amount of energy released as heat by the freezing of 13.3 g of a liquid substance, given that the substance ha
spin [16.1K]

From the calculations, the heat of fusion of the substance is 0.73 kJ

<h3>What is is the heat of freezing?</h3>

The heat of freezing is the energy released when the substance is converted from liquid to solid.

Now we know that the molar mass of the substance is 82.9 g/mol  hence the number of moles of the substance is;  13.3 g /82.9 g/mol  = 0.16 moles

Now the heat of fusion shall be;

H = 4.60 kj/mol * 0.16 moles

H = 0.73 kJ

A solution containing HCl and the weak acid HClO2 has a pH of 2.4. Enough KOH (aq) is added to the solution to increase the pH t
astraxan [27]

Answer:

\boxed{\rm \text{[ClO$_{2}^{-}$] increases}}

Explanation:

At the beginning, you have two reactions happening:

\rm HCl + H$_{2}$O$ $\, \longrightarrow \,$ H$_{3}$O$^{+}$ + Cl$^{-}$\\\rm HClO$_{2}$ + H$_{2}$O$ $\, \rightleftharpoons \,$ H$_{3}$O$^{+}$ + ClO$_{2}^{-}$

As you add KOH(aq), it does two things:

  1. It increases the volume of the solution.
  2. It reacts with the hydronium ions to form water.

A) The HCl is completely ionized. The Cl⁻ does not react, but it is diluted when the volume of the solution increases. [Cl⁻] decreases.

B) The KOH reacts with the H⁺ and removes it from the solution. [H⁺] decreases.

C) When all the H⁺ from the HCl has been neutralized, the KOH starts neutralizing the H⁺ from the HClO₂. According to Le Châtelier's Principle, more HClO₂ will dissociate to replace the decreased H⁺. [HClO₂] decreases.

D) As HClO₂ reacts, it forms ClO₂⁻. \boxed{\rm \textbf{[ClO$_{2}^{-}$] increases}}
