name four states of matter​

Answer:  an element with a high electronegativity and an element with a single valence electron  

is the correct answer

_______________________________________________________

Answer:

_______________________________________________________

"Why?"

For instance, fluorine is the most reactive non-metal element on the periodic table. Due to it's small size, as well as it's strong electronegativity, fluorine has a strong tendency to accept electrons from other atoms and ions. But when Fluorine comes in contact with Hydrogen (a single valence electron element), for instance, it immediately reacts, resulting in an explosion.

Answer :

0.9999432 g/cm^3

The density of water in g/ml up to 4 significant figures at 6°C is 0.9999432 g/cm³.

Significant figures are used for establishment  of a number which is presented in the form of digits. These digits give a meaningful representation  to the numbers.

The significant figures are the significant digits which convey the meaning according to the accuracy. These provide precision to the numbers and hence are called as significant numbers.There are rules for counting significant figures which are as follows:

1)All non-zero digits are significant .

2)All zeroes which occur between non-zero digits are significant.

3)All zeroes to the left and right of  a non-zero digit are not significant.

4) All zeroes on right  of decimal are significant if a non-zero number follows them.

5)All zeroes on right side of non-zero digit are significant

Answer:

A. How Acidic the solution is

Explanation: pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Answer:

A

Explanation:

The pH of a solution indicates it's acidity or alkalinity. The pH scale is an inverse logarithm that ranges from 0 to 14. Anything below 7.0 (ranging from 0.0 to 6.9) is acidic and anything above 7.0 ( from 7.1 to 14. 0) is basic or alkaline.

The flow chart related to the ionic bond in sodium chloride is as follows;

Sodium is in group 1 of the periodic table. It contains 11 electrons as shown by its electronic configuration. It forms sodium ion by loss of one electron. Group 1 elements form an univalent positive ion.

Chlorine is in group 17 of the periodic table. It has 17 electrons. It forms chloride ion by gaining one electron leading to the formation of sodium chloride.

Explanation:

The parts of the text on the page that use examples of how the flow of matter through a system is energy driven and has the capacity to do work are;

1) The flow of water down rivers passing through hydro power dams to perform the following works;

2) The flow of electrons that corresponds to the flow of electricity (in the reverse direction) to perform the following works;

3) The lifting of the hammer by the cam which gains gravitational potential energy that is converted to kinetic energy as the hammer drops

The hammer is repeatedly lifted and dropped by the cam to do the following work

4) The chemical potential energy stored in bonds by virtue of the relative atomic distances which produces kinetic energy from the chemical potential energy

Answer:

The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

so simple question.

Answer:

Potential energy is stored energy that an object has because of its position.

Explanation:

Consider an example where a ball is thrown from a tall building. The point at which the ball is at its maximum height is said to have the maximum potential energy. As the ball gradually falls down, the potential energy decreases and turns into another form of energy, kinetic energy (energy in the form of motion). The ball at its peak position had stored energy, however, as soon as it begins moving, the stored energy will become less.  

You can think of it this way where the ball has less and less distance to cover when falling downwards from the building. This shorter distance covered by the ball is proportional to the potential energy, so when the ball is about to hit the ground, the potential energy will be close to 0.

Answer:

d. a row of elements

Explanation:

Elements that are in the same group, have same number of electrons and make up a column in a periodic table.

[tex].[/tex]

The phrase which best describes a period on the periodic table is; a row of elements.

The elements in the periodic table are divided into rows and columns. The rows are called the periods while the columns are called the groups.

This means that a period is best described as a row of elements from the foregoing.

Therefore, the correct answer is option D: a row of elements.
