The Scientific Notation of  Xenon’s density : 1.31293 × 10²

<h3>Further explanation</h3>

Scientific Notation consists of 2 parts

1. the first part: the first digit followed by the decimal point

2. The second part: the power of 10 which shows the number of digits after the decimal point

Xenon's density = 131.293

First digit = 1, then we give the decimal point and the next digit

The power of 10 is determined from the number of decimal points moved from the original decimal point

Because we move the decimal point two digits to the left, the power of 10 has the number 2 (10²)

So that the Scientific Notation form becomes:

1.31293 × 10²

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.

a material has a density of 8.9 g/cm^3. You have six cubic centimeters of the substance. What is the material's mass in grams?
Svet_ta [14]
If the formula for density=m/v, you can manipulate this formula to the the mass. After manipulation, you get the equation for mass to be: m=density * volume. With density and volume given, we can find the mass.

mass= (8.9) * 6 = 53.4grams

Explain why organic reactions occur at a slower rate than inorganic reactions. What do chemists use to speed these reactions up?
8_murik_8 [283]
The organic particles  are molecules. Because of strong covalent bonding in the molecule, organic compounds do not react quickly. Reactions with organic compounds are generally slower than inorganic reactions due to this fact. 

Increasing temperature speeds up a reaction because of there being more collisions and those collisions have higher energy. Also the high concentration of the chemicals, particle size and there being a suitable catalyst present. ( Though this process is harmful should it be used in modifying results in food grains and meats.)
