Answer:

D. two-stroke cylinder engine.

Explanation:

<u>Two-stroke cylinder engine:</u> In chemistry, the term "two-stroke cylinder engine" is described as one of the types of "internal combustion engine" that tends to complete a single "power cycle" possessing two different strokes of the "piston" during a particular "crankshaft revolution".

<u>It generally</u> consists of two different strokes that are being often known as power or exhaust and suction stroke.

<u>In the question above, the given statement signifies the "two-stroke cylinder engine". </u>

What is ΔG° at 298 K for the following equilibrium? Ag+(aq) + 2NH3(aq) Ag(NH3)2+(aq); Kf = 1.7 × 107 at 298 K a. 41 kJ b. 0 c. –
jekas [21]

Answer:

ΔG° = 41.248 KJ/mol (298 K); the correct answer is a) 41 KJ

Explanation:

Ag+(aq)  +  2NH3(aq)  ↔ Ag(NH3)2+(aq)

⇒ Kf = 1.7 E7; T =298K  

⇒ ΔG° = - RT Ln Kf.....for aqueous solutions

∴ R = 8.314 J/mol.K

⇒ ΔG° = - ( 8.314 J/mol.K ) * ( 278 K ) ln ( 1.7 E7 )

⇒ ΔG° = 41248.41 J/mol * ( KJ / 1000J )

⇒ ΔG° = 41.248 KJ/mol

Cyclopropane is converted to propene in a first–order process with a rate constant of 5.4 × 10–2 hour–1 . The initial concentrat
Hitman42 [59]

Answer:

The concentration of cyclopropane after 22.0 hour is 0.0457 M.

Explanation:

Conversion of cyclopropane into propene follows first order kinetics.

The integrated rate of first order kinetic is given by :

[A]=[A_o]\times e^{-kt}

[A_o] = Initial concentration of reactant

[A] = final concentration of reactant after time t

k = rate constant of the reaction

We have :

Rate constant of the reaction = k = 5.4\times 10^{-2} hour^{-1}

[A_o]=0.150 M

t = 22.0 hour

[A] =?

[A]=0.150 M\times e^{-5.4\times 10^{-2} hour^{-1}\times 22.hour}

[A]=0.0457 M

The concentration of cyclopropane after 22.0 hour is 0.0457 M.
