Increased industrialization has caused a rise in harmful acid rain precipitation that affects plant and marine life. A sample of

acid rain has a proton concentration 10,000 times greater than pure water and more than 100,000 times greater than seawater. What is the approximate pH of this sample?

Answer:

pH of the sample of acid rain is 3.

Explanation:

Pure water has a theoretical pH of 7.00. As pH = -log [H⁺], [H⁺] = 1x10⁻⁷M

Now, the sample of acid rain has a proton concentration 10,000 times greater than pure water. That is:

[H⁺] = 10,000 * 1x10⁻⁷M = 1x10⁻³M

The pH of this sample is:

pH = -log 1x10⁻³M

<h3>pH = 3</h3>

Is the entropy change favorable or not, when a nonpolar molecule is transferred from water to a nonpolar solvent?
jonny [76]

Answer:

Entropy change is favorable when a nonpolar molecule is transferred from water to a nonpolar solvent.

Explanation:

A nonpolar molecule is not miscible in water (polar solvent). Therefore, when mixed together, each specie will cluster together and solvation will not happen.

However, when you tranfer the nonpolar molecule to a nonpolar solvent, the solvent molecules will interact with the nonpolar molecule. This will increase entropy as the level of disorder will increase with solvation.

"the osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant
ASHA 777 [7]

Answer: -

The concentration is 0.91 mol/ L

Explanation: -

The osmotic pressure = 23 atm

Absolute temperature = 309 K

Universal gas constant = 0.08206 L atm mol⁻¹ K⁻¹

We know the formula

Osmotic pressure = molar concentration x universal gas constant x absolute temperature

Plugging in the values

23 atm = molar concentration x 0.08206 L atm mol⁻¹ K⁻¹ x 309 K

Molar concentration = \frac{23}{0.08206 x 309} mol/ L

                                  = 0.91 mol / L

What temperature in degrees c is the freezing point of water?
guajiro [1.7K]
The freezing point of water is 0° C. The Celsius (centigrade) scale is based off of water, with the freezing point at 0° and the boiling point at 100°. (Google will probably tell you this in 10 seconds, then you wouldn't have had to wait 7 hours!)

Help, Kinda struggling here
KengaRu [80]

The water cycle will be discussed here.

<h3>What is Water cycle?</h3>

This is defined as the continuous manner in which water is moved within the earth and the atmosphere.'

The water cycle comprises of steps such as:

  • Evaporation
  • Condensation
  • Precipitation

Humans however disrupt water cycle through the damming of rivers and deforestation.
