In order to reduce dependence on imported oil, the government of Jalica has imposed minimum fuel-efficiency requirements on all

new cars, beginning this year. The more fuel-efficient a car, the less pollution it produces per mile driven. As Jalicans replace their old cars with cars that meet the new requirements, annual pollution from car traffic is likely to decrease in Jalica.Which of the following, if true, most seriously weakens the argument‘?(A) In Jalica, domestically produced oil is more expensive than imported oil.(B) The Jalican government did not intend the new fuel-efiiciency requirement to be a pollution-reduction measure.(C) Some pollution-control devices mandated in Jalica make cars less fuel-efficient than they would be without those devices.(D) The new regulation requires no change in the chemical formulation of fuel for cars in Jalica.(E) Jalicans who get cars that are more fuel-efficient tend to do more driving than before.

Which compound is most likely to follow second-order kinetics in a substitution reaction? (ch3)2chbr ch3ch2br (ch3)3cch2br ch3br
Inga [223]

Substitution reaction<span> monitors second-order kinetics; that is, the degree of the reaction hinge on on the concentration of two first-order reactants. In the circumstance of bimolecular nucleophilic </span>substitution, these two reactants are the nucleophile and the haloalkane. So for this problem, the answer is ch3br.

50 POINTS!!!
8090 [49]

Answer:

Pressure = 4.81atm

Explanation:

Pressure = ?

Temperature = 20°C = (20 + 273.15)K = 293.15K

Volume = 2.50L

R = 0.082J/mol.K

n = 0.5mol

From ideal gas equation,

PV = nRT

P = pressure of the ideal gas

V = volume the gas occupies

n = number of moles of the gas

R = ideal gas constant and may varies due to unit of pressure and volume

T = temperature of the ideal gas

PV = nRT

Solve for P,

P = nRT/ V

P = (0.5 * 0.082 * 293.15) / 2.50

P = 12.01915 / 2.50

P = 4.807atm

P = 4.81atm

The pressure of the ideal gas is 4.81atm

Rank the following substances/solutions in order of lowest boiling point to highest boiling point where 1 has the lowest boiling
poizon [28]

Answer:

1) pure water

2) 0.75 m CaCl2

3) 1.0 m NaCl

4) 0.5 m KBr

5) 1.5 m glucose (C6H12O6)

Explanation:

Boiling point elevation is a colligative property. Coligative properties are properties that depend on the amount of solute present in the system. The boiling point of solvents increase due to the presence of solutes.

The boiling point elevation depends on the number of particles the solute forms in solution and the molality of the solute. The more the number of particles formed by the solute and the greater the molality of the solute, the greater the magnitude of boiling point elevation.

The order of decreasing hoping point elevation is;

1) 0.75 m CaCl2

2) 1.0 m NaCl

3) 0.5 m KBr

4) 1.5 m glucose (C6H12O6)
