A bus traveled south west for 422 kilometers. The entire trip took 3 hours. Calculate the velocity.

ahrayia [7]

V= d/t
v=speed
d=distance
t=time

So v= 422/3
v =140.667m/s

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.

Write a detailed paragraph about how a volcano is formed. be sure to

victus00 [196]

Answer:

okay but give me brainliest

Explanation:

A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Volcanic flows are called lahars.
