If the equilibrium system were stored in a vessel (with no heat transfer into or out of the vessel from the surroundings), predict what would happen to the temperature reading on a thermometer placed in the solution when hydrochloric acid is added. explain.

The system will experience a reaction with adding of the element hydrochloric acid (HCl). The equilibrium is shifted and the potential energy, where it will be absorbed by the energetic component of the product as sch the overall temperature reading will also decrease as the heat due to potential energy is absorbed and/or contained.

it is called kinetic energy

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
