Why is nh3 classified as a polar molecule

Chemistry
1 answer:
Yanka [14]3 years ago
4 0

Explanation:

An ammonia (NH_{3}) molecule contains electronegative nitrogen atom. The difference between electronegativity of nitrogen and hydrogen atom is high.

Therefore, nitrogen will attract the shared pair of electrons more towards itself. As a result, there will be partial positive charge on hydrogen and partial negative charge on nitrogen.

Thus, due to these charges NH_{3}  is polar in nature.

Calculate the pH of a solution formed by dissolving 0.040 moles of solid sodium lactate, NaC3H5O3, in 50.0 mL of 1.0 M HC3H5O3.
natima [27]

The pH of the solution is 3,76

Why?

To solve this problem we have to apply the Henderson-Hasselbach equation, which is used whenever we need to calculate the pH of a solution of an acid HA (Lactic Acid) and its conjugate base A⁻ (Sodium Lactate)

We can use either moles or concentrations for this equation. In this case, we are going to use the moles, and we are going to take the pKa of lactic acid as 3,86:

pH=pKa+log(\frac{nA^- }{nHA} )=3,86+log(\frac{(0,04moles)}{(0,05mL)*(1.0M)} )\\\\pH=3,76

Have a nice day!

Why is water sometimes called the ""universal solvent?"".
Marysya12 [62]

Answer:

Water is called the universal solvent because more substances dissolve in water than in any other chemical. This has to do with the polarity of each water molecule. The hydrogen side of each water (H2O) molecule carries a slight positive electric charge, while the oxygen side carries a slight negative electric charge.
