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

Determine the empirical formula for a compound that is found to contain
Sphinxa [80]

Answer:

The empirical formula is PCl3

Explanation:

Mass of P is 30.97 g, thus 1.523 g of P equivalent to 0.05 moles of P

Mass of Cl is 35.45 g, thus 5.228 g of Cl equivalent to 0.15 moles of Cl

Therefore moles of P : moles of Cl = 0.05:0.15 = 1:3

Therefore the empirical formula, PCl3

Arrange the following elements in order from least to greatest electronegativity:<br> Ca, F, Ne, Fe?
Burka [1]

Answer:

The electronegativity from order of least to highest is:

Ne, Ca, Fe, F

Explanation:

Elements in the periodic table have been arranged based on their level of electronegativity (which is the ability of an atom to attract electrons).

According to Paulings scale of rating elements based on their electronegativity, the electronegativity value of Fe, Ca, Ne, and F are 1.83, 1, 0 and 3.98 respectively.

Hence, based on Pauling scale, the order of electronegativity from least to highest is:

Ne > Ca > Fe > F
