Based on periodic trends and the data in the table above, which of the following is the most probable value for the ionic radius
marissa [1.9K]

Based on periodic trends, the most probable value for the ionic radius of K⁺ is 133 pm.

<h3>What are periodic trends?</h3>

Periodic trends are the observation which are seen in the chemical and physical elements found in the periodic table.

Periodic trends is based on the periodicity of elements.

Periodicity is the variation seen in the chemical and physical properties of the elements in the period table in a regular pattern, both down the groups and across the periods.

The periodic trends observed in metallic ions is that ionic radius of metallic ions increase down a group but decreases across a period.

Based on this periodic trend, the most likely size of the potassium ion, K⁺ is 133 pm.

In conclusion, the ionic radius of metallic ions increase down a group and decrease across a period.

Match the project to the appropriate field of chemistry (inorganic chemistry,
BlackZzzverrR [31]

Chemistry is composed of many sub-disciplines such as inorganic chemistry, physical chemistry, biochemistry, organic chemistry, analytical chemistry etc. The following is a matching of certain projects against the sub-discipline in chemistry where they rightfully belong.

1) Determine the composition of a moon rock sample..... analytical chemistry

2) Do research on making a new medicine to treat high blood pressure..... biochemistry

3)  Investigate ways to regulate the rate of gasoline burning in an automobile engine......physical chemistry

4) Develop a plastic that can be decomposed by bacteria......organic chemistry

5) Improve the method for extracting iron from iron ore.....inorganic chemistry

The sub-disciplines of chemistry all work together to make the world a better place. The science of chemistry is very pivotal hence it is applicable in every area of science and technology.

Analytical chemistry, as the name implies, deals with "analyzing" or finding out the components of materials.

Biochemistry is concerned with the study of molecules that have biological activity such as medicine to treat high blood pressure.

One key area of physical chemistry is chemical kinetics which discusses rates of chemical reactions. This sub-discipline is important when investigate ways to regulate the rate of gasoline burning in an automobile engine.

Organic chemistry is the chemistry of carbon compounds. It studies compounds that contain long chains of carbon such as those found in plastics.

Inorganic chemistry deals with the study of the elements including the extraction of elements such as iron from its ore.

In the chemical reaction below, what Is the product? C+o2 -&gt; Co2
vlada-n [284]

Answer:

CO₂

Explanation:

The product of the reaction is CO₂.

In a chemical reaction, the product is the substance usually found on the right hand side of the expression.

  Reaction equation is given as;

          C  +  O₂  →  CO₂  

In this reaction, C and O₂ are the reactants

  CO₂ is the product of the reaction.

  • This reaction is called a combination reaction in which two species combines to give a product.

What postulate of the kinetic molecular theory best explains why gases have high fluidity? because collisions between gas partic
slavikrds [6]

the elasticity of gas particle collisions, there is no energy loss when the particles pass one another. Gases are composed of a very large number of small particles, which spread out and avoid contact with one another.

<h3>Which of the following gas postulates from the kinetic molecular theory best explains why pressure exists in gases?</h3>

As the quantity of gas particles in the container rises, so does the frequency of wall interactions and subsequently the pressure of the gas. The average kinetic energy of a gas particle is exclusively dependent on the temperature of the gas, says the theory's final postulate. As the volume of gas particles inside the container grows, more of them will collide with the walls, increasing the pressure and the frequency of collisions.
