Annual precipitation rates can be collected for several years, added together, and divided by the number of years to obtain an a
Art [367]

The average annual precipitation has been calculated by dividing the sum of average rainfall to the number of years. Thus, the given statement is true.

Precipitation has been given as the amount of water in the atmosphere that has been to fall off on the earth.

<h3 /><h3>Average Annual Precipitation</h3>

The average has been defined as the mid-value for the number readings. The average precipitation has been the approximate fall of water on the earth in the specified period.

The average annual precipitation has been calculated with the ratio of the sum of the average rainfall in the number of years to the total number of years. Thus, the given statement is true.

The mercury-201 nuclide radioactively decays by electron capture. Write a balanced nuclear chemical equation that describes this
ICE Princess25 [194]

Answer:

Explanation:

Electron capture is a form of beta decay in which the nucleus of a radionuclide captures an electron. In the case of mercury-201, the equation below illustrates that

²⁰¹₈₀Hg + ⁰₋₁e   ⇒  ²⁰¹₇₉Au

As can be seen above, the electron capture reduces the atomic number by one unit leading to the production of a new radioisotope (because of the change in atomic number).

Which is formed by positive ions from a base and negative ions from an acid? a. Salt b. Vinegar
max2010maxim [7]

The formation of salt takes place by the sharing of positive ions from a base and negative ions from an acid.

This is based on the concept and principles of neutralization. The process of neutralization is the name of a chemical reaction between an acid and a base.

Hence, the correct option is a.

pH refers to a measure of how acidic or basic a solution is.

A pH is a measure of how basic or acidic a substance is. pH has a range of 0-14. A pH greater than 7 means the substance is basic.

A pH less than 7 means the substance is acidic. When the pH is exactly 7 that indicates that the substance is neutral.

Hence, the correct optiion is a.

The pH of a solution that has the same number of hydrogen ions as hydroxide ions is 7.

Hence, the correct option is c.

Baking soda has the greatest number of hydroxide ions.

Thus is because of the pH is 9. So, it will be more basic.

Hence, the correct option is a.

Hydrochloric acid will be least likely to completely dissolve in water.

Hence, the correct option is a.

Antacid is taken to get relieve from heartburn describes that the antacid is acidic and will raise the pH of the esophagus.

Hence, the correct option is c.

Acids measure below 7 describes the pH scale.

Hence, the correct option is a.

The order of these solutions from strong acid to strong base is  

Ammonia>battery acid>stomach acid>antacid>baking soda.
