Answer: 225 joules.
Explanation:
If this a one dimension problem, this is the motion is in the same direction of the force, the equation for work is:
Work = distance × force
⇒ Work = 15 m × 15 N = 225 joules.
This is a special case of the general equation
Work = |F| |displacement| cosine (angle between the force and displacement)
When force and displacement are in the same direction, the angle is 0, so cos(0) = 1. This is the two vectors are parellel and the work is just the product of the two magnitudes (force and distance)
Explanation:
When a strong acid, say
reacts which a weak base, say
, the reaction is shown below as:-

The salt further reacts with water as shown below:-

Formation of
lowers the pH value of the solution as more hydrogen ions leads to less pH.
I don’t even know that’s just weird
Answer:
1.5 Molar solution in KCl
Explanation:
Definition of molarity => moles of solute / Volume of solution in Liters
Given 3.00 moles of solute dissolved in 2Liters of solution
Molarity of [KCl] = 3.00 moles KCl / 2Liters solution = 1.5 Molar solution in KCl
