Elements in the same group on the periodic table have the same number of valence electrons, but elements in the same period will increase the number of valence electrons by one from left to right on the periodic table.

TRUE OR FALSE

Answers

Answer 1

Answer:

True

Explanation:

plz give me brainiest

Answer 2

Answer:

True

Explanation: If you take a look at a periodic table you will see a decimal number for example 7 N (Nitrogen) 14.01, the 14.01 is the total AMU (atomic mass unit) of the element witch includes the valence electrons. Hence true would be the correct answer.

What are plate tectonics ?

The tectonic plates of different parts of the earth's crust are always in motion, causing changes in the planet's landforms .

However the globe would look same due to presence of  plate tectonics with a stable climate, mineral and oil deposits, and oceans with a chemical balance.

These plates are mainly 100 km thick, are made up of this crustal layer which continue to float on the warm and thick mantle, and create mountains

These plates are puzzle like matching pieces on the surface of the planet that , the movement of the plates caused by the mantle convection from below the lithosphere.

There are two primary types of tectonic plates such as continental tectonic plates and oceanic tectonic plates. Some plates are large, while some are smaller.

Coal, a fossil fuel made from the remains of swamp plants, has been found in Antarctica. Which of the following is the most reasonable explanation for how this is possible when 98% of Antarctica is now
covered in ice?
The coal was transported by animals that ate the swamp plants.
The climate of Antarctica has become milder due to its closeness to the ocean.
The climate of Antarctica was probably much warmer in the past than it is today.
The coal was transported through large convection currents and uplift in the mantle.

Answers

Answer:

The climate of Antarctica was probably much warmer in the past than it is today.

Explanation:

There are little things living there now. Coal takes millions of years to form. There must have been much more living things there in the past (when it was warmer) to make coal.

When cells are damaged, new cells are created by cell a process called cell division. The cell theory supports this fact as it states that all cells have a nucleus that divides.

What is the cell theory?All living things are primarily composed of cells, which serve as both the basic structural and organizational units of all living things.  According to the biological notion known as "cell theory," all cells are descended from previously existing cells. All living things are composed mostly of cells, which also serve as the fundamental unit of reproduction.  The cell theory is based on the following three basic postulates: Every living thing is made up of one or more cells.The fundamental unit of structure and organization in organisms is the cell. New cells are created from pre-existing cells. Theodor Schwann and Matthias Jakob Schleiden are two scientists usually credited with developing or discovering the cell theory. In 1839, Schleiden claimed that every structural element of a plant is composed of cells or is a cell-derived substance. Additionally, he suggested that cells were created through a crystallization process that took place either inside or outside of other cells.

What’s the difference in concentration of hydronium Ions between pH1 and pH4?


a) x 2.6

b) x 1000

c) x 4

d) x 10

Answers

Answer:

The difference in concentration of hydronium Ions between pH1 and pH4 is 1000 times.

The difference in concentration of hydronium Ions between pH1 and pH4 is - Option b) x 1000.

pH scale is a scale or measure to find the strength of acidity or basic nature of a solution or substance. pH 1 is acidic and pH 14 is most basic on scale.

Acids combine with water molecules to form hydronium ion, H3O+. Therefore, pH formula in aqueous solution becomes-

pH = - log [H3O+].

taking antilog on both the sides, the concentration would be calculated as

[H3O+] = antilog (- pH)

In the first case, pH given is 1. So,

=> [H3O+] = antilog (- 1)

= 0.1  

In the second case, pH given is 4. So,

=> [H3O+] = antilog (- 4)

= 0.0001  

Thus, the concentration of hydronium ion at pH 1 is around 1000 times greater than that of concentration at pH 4.

What are desert plants?

Desert flora that require water conservation Prairie plants that must withstand flames desert flora that require water, conservation thick waxy covering would most likely be a useful adaptation.

The challenge for plants that thrive in highly dry environments is finding and retaining water.

Xerophytes are plants that can survive in extremely arid conditions. Their adaptations may aid them in consuming more water, reducing water waste, or storing water for later use.

Therefore, water is so scarce in deserts, plants there need to minimize water waste. They have thin foliage that enable them to retain more water during the summer.

A Tomato Has A Proton Concentration Of 0.00006 M. How Would You Calculate The PH?

Answers

Answer:

Option b. is correct

Explanation:

If hydronium ion concentration [tex]H_3O^+[/tex] is given then pH is given by [tex]-log[H_3O^+][/tex]

The hydronium ion refers to the hydrogen ion in aqueous solution.

A Tomato has A Proton Concentration Of 0.00006 M

Here, 0.00006 is equal to 6 × [tex]10^{-5}[/tex]

So,

pH is given by - log [6 × [tex]10^{-5}[/tex]]

Option b. is correct

The pH of the tomato which has a proton concentration of 0.00006 M is given by –Log (6×10¯⁵)

The correct answer to the question is Option B. –Log (6×10¯⁵)

From the question given above, the following data were obtained:

proton concentration [H⁺] = 0.00006 M = 6×10¯⁵ M

pH =?

The pH of tomato can be obtained as follow:

pH = –Log [H⁺]

pH = –Log (6×10¯⁵)

Thus, the correct answer to the question is Option B. –Log (6×10¯⁵)

True or False

Answers

Answer:

true

Explanation:

dietary fiber build muscle and flexibility

Dietary fiber is one of the components of a nutrient and balanced diet. Dietary fiber in the diet can build muscle and flexibility. Thus, the statement is true.

What is dietary fiber?

Dietary fiber along with the functional fibers makes the total fiber that makes part of the diet and is considered to be nutritious. They are homopolysaccharides that are made of various similar monomers linked concurrently by the glycosidic linkage.

Dietary fiber is composed of various units of cellulose linked chemically by the beta (1 - 4) glycosidic linkage. They have been known as roughage which are plant parts that are undigestable. Though they cannot be absorbed, but they ensure a smooth digestive and excretory process.

The presence of dietary fiber in the diet increases flexibility and muscle mass by decreasing body fat and is found in beans, broccoli, avocados, berries, apples, etc. It eliminates fats and other wastes from the body by promoting regular bowel movements.

Therefore, the statement is true.
