Answer : The correct option is, (A) The hydronium ion concentration in the solution.

Explanation :

Acid-base indicator : It is used in the titration. It is a substance which changes the color with the pH.

Acid-base indicator are the weak acid-base indicators which when dissolved in the water, it dissociate slightly and form the ions.

When the indicator dissolved in the water then it dissociate into $H^+$ ion and then the color change of the pH indicator.

Let us consider an indicator which is a weak acid, with the formula HIn.

At equilibrium, the chemical equation of acid indicator will be,

$HIn \rightleftharpoons H^++In^-$

Hence, the correct option is, (A) The hydronium ion concentration in the solution.

A bowl contains 4 red balls and 2 green balls. Two balls are selected simultanesouly and at random. What is the conditional prob

AlladinOne [14]

Answer:0.6

Explanation:

Given

Bowl contains 4 red and 2 Green balls

Probability of selecting two red balls given atleast one of the ball is red + Probability of selecting two red balls given that no ball is red =1

Probability of selecting two red balls given that no ball is red $=\frac{Probability \ of\ selecting\ two\ red\ balls\ out\ of\ 4\ balls}{probability\ of\ selecting\ 2\ balls\ out\ of\ 6 balls}$

$P=\frac{^{4}C_2}{^{6}C_2}$

$P=\frac{2}{5}$

Required Probability $=1-\frac{2}{5}=\frac{3}{5}$

how much work does tension do on the laptop as it moves 2.0 mm ? express your answer with the appropriate units.

8090 [49]

The work done by tension force of 14N applied on the laptop by a rope as it moves 2.0 mm up the slope is 0.028 J

W = F d cos θ

W = Work done

F = Force

d = Displacement

θ = Angle between force and displacement vector

F = 14 N

d = 2 mm = 0.002 m

θ = 0

W = 14 * 0.002 * 1

W = 0.028 J

Work done is the change in energy of an object. So if an object moves a certain distance, work is done on the object. If the force and displacement are perpendicular to each other there is no work done on the object.

Therefore, the work done by tension on the laptop is 0.028 J
