Run off

Explanation:

Run-off are the water sources that becomes polluted as they travel over the earth surface.

Surface run-off are water that moves on the earth surface. This water is a component of the water cycle which usually originate from precipitation.

As the water moves through different terrain it comes into contact with different pollutants.
Some of these run-off travels through mines, waste disposal sites among others.
This leads to the contamination of this form of water as it moves through these earth materials.
They are the most polluted water

Many people have a tendency to think that heat and temperature are the same thing. However, this is not true. Heat describes A.

enyata [817]

The correct answer is actually

B) energy that flows from warmer objects to cooler objects.

because temperature is a measure of the average amount of energy possessed by an object due to the random motions of its particles. Heat is the energy that flows from warmer objects to cooler objects. Heat cannot flow in the opposite direction.

g Tom's roommate Bob spilled crystal violet solution on his lab coat, and Tom offers to use some lye (sodium hydroxide solution)

irina [24]

Answer:

Tom is correct. The rate of reaction of Crystal violet and NaOH is first order with respect to NaOH, hence, a higher concentration of NaOH corresponds to a higher rate of reaction; a faster reaction.

This means the speed of cleaning depends on the concentration of the lye used.

Explanation:

The reaction between Crystal violet and NaOH, represented as

CV⁺ + OH⁻ → CVOH

It is a reaction that is know to turn the violet colour of the crystal violet colourless.

The rate of the reaction is also known to be second order; first order with respect to Crystal violet and first order with respect to NaOH.

This means that the rate of reaction is directly proportional to the concentration of NaOH provided all other parameters such as the rate constant and the concentration of Crystal violet are constant.

Hence, the reaction becomes faster with an increased concentration of NaOH.

So, Tom is right, concentrated lye solution would remove the stain faster.

Bob is wrong.

Hope this Helps!!!
