Consider the reaction below. zn(s) + 2hcl(aq) mc029-1.jpg h2(g) + zncl2(aq) which product is a substance that is dissolved in solution?

Explanation:

A solid state is represented by (s) in a chemical reaction equation whereas when a compound is soluble in the solution then it is said to be aqueous solution and it is denoted as (aq) in a chemical reaction equation.

On the other hand, gas is denoted by a symbol (g) in the chemical reaction equation.

Therefore, in the reaction , zinc chloride () product is a substance that is dissolved in solution.

a displacement distance is size of displ

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
