The saturation index for a pool measures the balance between the acid level and the amount of minerals in pool water. Balanced water has an index value of 0. Water is highly corrosive or highly scale forming if the absolute deviation of the index value from 0 is greater than 0.5. Find the index values for which pool water is highly corrosive or highly scale forming.

Answers

Answer 1
Answer:

Answer: The water is highly corrosive when the saturation index < - 0.5 and

> 0.5

Explanation:

If the saturation index for a pool measures the balance between the acid level and the amount of minerals in pool water. Considering its balanced water has an index value of 0.

The water is highly corrosive when the saturation index < - 0.5 and

> 0.5

The mutual force of attraction between ions of opposite charges acn best be described as...A) an ionic bond
B) a polar covalent bond
C) an electronegative bond
D) a non-polar covalent bond

Answers

The mutual attraction of oppositely charged ions is called the ionic bond. Polar covalent bond is composed of unequal sharing between of non-metal elements which are non-ionic. Non-polar bond is composed on the other hand of equal sharing of these non-ionic elements. Hence, the answer is A.

Answer:

A) an ionic bond

Explanation:

The mutual force of attraction between ions of opposite charges can best be described as an ionic bond.

In an ionic bond, an atom picks up electrons from the other so it becomes into a strongly electronegative atom while the other becomes into a strongly electropositive atoms and, as ions of different signs, it is generated an electrostatic attraction force between them.

A transformer has a primary voltage of 115 V and a secondary voltage of 24 V. If the number of turns in the primary is 345, how many turns are in the secondary? A. 1,653
B. 690
C. 72
D. 8

Answers

There are numerous information's of immense importance already given in the question.
Primary voltage of the transformer (V1) = 115 V
Secondary voltage of the transformer (V2) = 24 V
Number of turns in the primary (T1) = 345
Let us assume the number of turns in the secondary = T2
Then
(V1/V2) = (T1/T2)
(115/24) = 345/T2
115T2 = 345 * 24
115 T2 = 8280
T2 = 8280/115
     = 72
So the correct option among all the options given in the question is option "C".

Answer:

The is 1653

Explanation:

Primary Voltage = # of turns in primary

Secondary Voltage  # of turns in secondary

115 V = 345

24 V     # of turns in secondary

115\25=4.79167

4.79167 = 345

               # of turns in secondary

4.79167 * 345 = 1653.12

When rounded 1653

Highlight the basic points in Lewis and Langmuir theory of electrovalency

Answers

The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges. 

The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds. 

Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas

The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.
