Explanation:

pH is a major parameter that is measured in determining the water quality. It indicates whether a water source is of good quality to be used for drinking purposes and other house hold needs. In addition, maintaining the appropriate pH is critical for some chemical reactions as well. The pH of a system is dependent on the concentration of hydrogen ions present in that system. The concentration of hydrogen ions in a solution is the amount of hydrogen ions (in the units of mol) present in a liter of solution. pH is the logarithmic value of the inverse of the hydrogen ion concentration. This is the relationship between hydrogen ions and pH.

Round off each number to the indicated number significant figures (sf):
qaws [65]

Answer :

(a) The given number in 2 significant figures will be, 3.6\times 10^3

(b) The given number in 4 significant figures will be, 3.583\times 10^1

(c) The given number in 3 significant figures will be, 2.24\times 10^1

Explanation :

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

(a) The given number 00003554 converted into 2 significant figures.

In 00003554, there are 4 significant figures. Now we have to convert it into 2 significant figures.

The given number in 2 significant figures will be, 3.6\times 10^3

(b) The given number 35.8348 converted into 4 significant figures.

In 35.8348, there are 6 significant figures. Now we have to convert it into 4 significant figures.

The given number in 4 significant figures will be, 3.583\times 10^1

(c) The given number 22.4555 converted into 3 significant figures.

In 22.4555, there are 6 significant figures. Now we have to convert it into 3 significant figures.

The given number in 3 significant figures will be, 2.24\times 10^1

The sulfur atom of sulfur dioxide is considered to be sp2-hybridized. The expected bond angle is 120°, but is actually slightly
Alja [10]

Answer: The bonds are intermediate between double and single bonds

Explanation:

A closer look at the diagram below shows that the bonds in sulphur IV oxide are intermediate between double and single bonds. Hence they do not have the exact bond angle of single bonds. This is why the bond angle is not exactly 120°. There are two resonance structures in the diagram that clearly show this point.
