DanielleElmas [232]3 years ago
8 0

Answer:

(1) n-Octane

(2) 2-methyl-Heptane

(3) 3-methyl-Heptane

(4) 4-methyl-Heptane

(5) 2-ethyl-Hexane

(6) 3-ethyl- Hexane

Explanation:

We are given Octane which has the chemical formula as C8H18, and we need to find its three possible structures.

Isomerism is defined as the phenomenon in which a chemical compound will consist of the same chemical formula but it will have different orientation or bond arrangements. in simpler meaning isomers of a compound has same chemical formula but has different structures.

Some possible isomers of the compound Octane are given as in terms of their IUPAC names.

Chemical formula : C8H18

(1) n-Octane

(2) 2-methyl-Heptane

(3) 3-methyl-Heptane

(4) 4-methyl-Heptane

(5) 2-ethyl-Hexane

(6) 3-ethyl- Hexane

Find ∆G for a cell whose potential is +0.24 V with 4 moles of electrons exchanged.
Setler [38]
We need to use the following formula
ΔG= -nF E_{cell}

E_{cell}= 0.24V
n= 4 moles
F= constant= 96500C/mol

let's plug in the values.

ΔG= -(4)(96500)(0.24)= -92640 J or -92.6 kJ

A 12 gram piece of metal is heated to 300 °C from 100 °C with 1120 Joules of energy. What is the specific heat of the metal?
Sergeeva-Olga [200]

Answer:

The specific heat for the metal is 0.466 J/g°C.

Explanation:

Given,

Q = 1120 Joules

mass = 12 grams

T₁ = 100°C

T₂ = 300°C

The specific heat for the metal can be calculated by using the formula

Q = (mass) (ΔT) (Cp)

ΔT = T₂ - T₁ = 300°C  - 100°C   = 200°C

Substituting values,

1120 = (12)(200)(Cp)

Cp = 0.466 J/g°C.

Therefore, specific heat of the metal is 0.466 J/g°C.

The combustion of palmitic acid is represented by the chemical equation: C16H32O2(s) + 23O2(g) → 16 CO2(g) + 16 H2O(l) The magni
solniwko [45]

Answer:

The correct option is C

Explanation:

From the question we are told that

The reaction is

C_{16}H_{32}O_2(g) + 23O_2(g) \to 16 CO_2(g) + 16 H_2O(l)

Generally \Delta  H  =  \Delta  U + \Delta N*  RT

Here \Delta  H is the change in enthalpy

\Delta  U is the change in the internal energy

              \Delta N  is the difference between that number of moles of product and the number of moles of reactant

Looking at the reaction we can discover that the elements that was consumed and the element that was formed is O_2 and  CO_2 and this are both gases so the change would occur in the number of moles

So  

\Delta  H  =  \Delta  U + [16 -23]*  RT

\Delta  H  =  \Delta  U -7RT

The  negative sign in the equation tell us that the enthalpy\Delta_r H would be less than the Internal energy \Delta_r U
