Answer:

The last figure (with the name 3-Chloro-2-iodo-4-methylhexane) is correct.

Explanation:

---> It gives the correct numbering of the positions of each Iodine Chlorine and Methyl which are attached at 2, 3 and 4 respectively

---> and also the names are given on alphabetical order (i.e. first Chlorine then Iodine and then Methyl)

Find the equilibrium value of [CO] if Kc=14.5 : CO (g) + 2H2 (g) ↔ CH3OH (g) Equilibrium concentrations: [H2] = 0.322 M and [CH3

Annette [7]

Answer:

The equilibrium value of [CO] is 1.04 M

Explanation:

Chemical equilibrium is the state to which a spontaneously evolving chemical system, in which a reversible chemical reaction takes place. When this situation is reached, it is observed that the concentrations of substances, both reagents and reaction products, they remain constant over time. That is, the rate of reaction of reagents to products is the same as that of products to reagents.

Reagent concentrations and products in equilibrium are related by the equilibrium constant Kc. Being:

aA + bB ⇔ cC + dD

$Kc=\frac{[C]^{c} *[D]^{d} }{[A]^{a} *[B]^{b} }$

Then this constant Kces equals the multiplication of the concentrations of the products raised to their stoichiometric coefficients between the multiplication of the concentrations of the reactants also raised to their stoichiometric coefficients.

In this case:

$Kc=\frac{[CH_{3}OH ]}{[CO]*[H_{2} ]^{2} }$

You know:

Kc= 14.5
[H₂]= 0.322 M
[CH₃OH] =1.56 M

Replacing:

$14.5=\frac{1.56}{[CO]*0.322^{2} }$

Solving:

$[CO]=\frac{1.56}{14.5*0.322^{2} }$

[CO]= 1.04 M

The equilibrium value of [CO] is 1.04 M

A 350.0 ml sample of gas has a temperature of 22.7 C and a pressure of 0.914 atm. What temperature would be needed for the same

Rus_ich [418]

Answer:

Explanation:

We shall apply gas law formula

P₁ V₁ / T₁ = P₂V₂ / T₂

.914 x 350 / ( 273 + 22.7 ) = 1 x 220 / T₂

1.0818 = 220 / T₂

T₂ = 203.36 K

= - 69.64 ⁰ C

Which of the following statements describes a difference between a chemical change and a physical change in a substance

siniylev [52]

Explanation:

A physical change is one that alters the physical properties of matter (particularly the form and state).

A chemical change is one in which new kind of matter is formed. It is always accompanied by energy changes (evolution or absorption of energy in form of heat or light or both).

Now, the salient differences between physical and chemical changes;

Physical changes are easily reversible whereas chemical changes are not easily reversible.
Physical changes lead to the production of no new kinds of matter whereas chemical changes leads to the production of new kinds of matter.
Physical changes involves no change in mass whereas chemical changes involves change in mass.
Physical changes require little energy whereas considerable amount of energy is needed for chemical changes.
