Answer:

1325 L

Explanation:

For this excersise we assume gasoline as an octane.

The combustion is:

2C₈H₁₈  +  25 O₂ →  16 CO₂  +  18H₂O

2 moles of octane react to 25 moles of oxygen, according to stoichiometry.

If we have 4 moles of gasoline, we need (4 . 25)/2 = 50 moles of oxygen.

We can apply the Ideal Gases Law to solve this.

We convert T° to Absolute Value

35°C + 273 = 308K

P . V = n . R . T

V = (n . R . T) / P → (50 mol . 0.082 mol.K/L.atm . 308K) / 0.953 atm

Volume = 1325 L

Answer:

7.53*10²³ molecules of oxygen will you need.

Explanation:

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.

You can then apply the following rule of three: if by definition of Avogadro's Number 1 mole of oxygen gas contains 6.023*10²³ molecules, 1.25 moles contains how many molecules?

[tex]amount of molecules=\frac{1.25 moles*6.023*10^{23}molecules }{1 mole}[/tex]

amount of molecules= 7.53*10²³

7.53*10²³ molecules of oxygen will you need.

Answer: Mothballs have weak intermolecular forces.

No all substances do not behave like mothballs at normal conditions. Example: benzene , chloroform

Explanation:

Sublimation is a process of converting a substance from solid state to gaseous state without the formation of liquid at constant temperature.

A substance which undergoes sublimation is called as sublimating substance.

As mothballs is made of napthalene which has weak inter molecular forces of attraction between its molecules, it directly sublimes into gaseous state without leaving any residue and is called as a sublimating substance.

Not all substances behave like mothballs at normal conditions. Example: benzene , chloroform

Due to weak intermolecular attraction force mothballs will disappear and not every compound show this type of behavior like benzene and chloroform.

Mothballs are also known as Naphthalene balls, they are the aromatic organic compounds and they are the members of the sublimating substance family as they directly convert into gaseous state from the solid state.

In the mothballs or naphthalene balls, there is a weak attraction of force London dispersion force is present between their constitute particles, and in normal condition they show sublimation and gets disappear. Not all aromatic compounds behave like these balls as not in all compounds these types of force present, for example in benzene and chloroform strong covalent bond is present.

Hence, not all compounds behave like mothballs and they show that property due to weak attraction force.

Answer:

[tex]\boxed {\boxed {\sf 3. \ H-H}}[/tex]

Explanation:

To determine the polarity of a bond, we use the electronegativities of the individual atoms. The greater the difference, the more polar the bond.

1. H-Br

3.0-2.2=0.8

2. H-F

4.0-2.2=1.8

3. H-H

2.2-2.2=0.0

4. H-O

3.4-2.2=1.2

As we can see, the lowest difference is in hydrogen hydrogen at 0.0. You may also recognize that because they are 2 atoms of the same element, the electronegativity is the same for both, so it will equal 0. Since the electronegativity is 0, this is a nonpolar bond.

Explanation:

Answer: 0.071 moles of excess reactant [tex](O_2)[/tex] will be left over.

Explanation:

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

a) moles of [tex]NO[/tex]

[tex]\text{Number of moles}=\frac{21.6g}{30.01g/mol}=0.720moles[/tex]

b) moles of [tex]O_2[/tex]

[tex]\text{Number of moles}=\frac{13.8g}{32g/mol}=0.431moles[/tex]

[tex]2NO(g)+O_2(g)\rightarrow 2NO_2(g)[/tex]

According to stoichiometry :

2 moles of [tex]NO[/tex] require 1 mole of [tex]O_2[/tex]

Thus 0.720 moles of  [tex]NO[/tex] require=[tex]\frac{1}{2}\times 0.720=0.360moles[/tex] of [tex]O_2[/tex]

Thus [tex]NO[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess regaent.

moles of [tex]O_2[/tex] left = (0.431-0.360) = 0.071 moles

Arrhenius Base

Explanation:

"NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion. ... Acids provide the H+ ion; bases provide the OH- ion; and these ions combine to form water."
