17. Which type of chemical bond is formed between two atoms of bromine?

Answers

Answer 1

Answer: A non polar bond is formed between two bromine atoms. That means that the electrons are shared equally between the two atoms, and since we are sharing electrons, we use the term, 'covalent bond'.

What causes the exchange?

Diffusion

The process by which dissolved gases are exchanged between the blood and interstitial fluids is called diffusion because molecules from high concentrated region moves to the place of lower concentrated region.

We know that diffusion is a process in which molecules from a region of higher concentration moves to the region having lower concentration so the gases exchanged between blood and interstitial fluid so we can conclude that diffusion is the process by which dissolved gases are exchanged between the blood and interstitial fluids.

Answer:The process by which dissolved gases are exchanged between the blood and interstitial fluids is called internal respiration.

Explanation:

Physiologically respiration is defined as the passing of oxygen the external environment into the cells within tissues, and the transport of carbon dioxide in the opposite direction.

Respiration is divided into three:

1.) The external respiration: this involves the inhalation of air and exhalation of used gases.

2.) The internal respiration: this is defined as a process of diffusing oxygen from the blood, into the interstitial fluid and into the cells

3.) Cellular respiration: this involves the conversion of food to energy. Its further divided into aerobic respiration, which is a cellular respiration that requires oxygen and anaerobic respiration which does not.

According to the electron-cloud model of the atom, an orbital is a(1) circular path traveled by an electron around the nucleus
(2) spiral path traveled by an electron toward the nucleus
(3) region of the most probable proton location
(4) region of the most probable electron location

Answers

Answer : Option 4) Region of the most probable electron location.

Explanation : As per the electron cloud model of the atom, an orbital is a region where the probability of finding an electron is highest. According to this model which was used to identify the probable location of the electrons when they go around the nucleus of an atom.

This electron cloud model was different from the older Bohr atomic model by Niels Bohr.

According to the electron-cloud model of the atom, an orbital is a "region of the most probable electron location" In this mode, an electron can actually be in two places at once.

Calculate the ph and poh of a 0.0032 M solution of nitric acid NHO3

Answers

Answer:

HNO3 ->NO3²- + H+

Concentration of H+ ions= 0.0032M

pH = - log[ H+]

= - log (0.0032)

= 2.49

pH + pOH = 14

pOH = 14 - pH

= 14 - 2.49

= 11.51

pH = 2.49 and pOH = 11.51

Using less water is one way to practice watera. filtration.
b. distribution.
c. conservation.
d. irrigation.

Answers

Answer: Option (c) is the correct answer.

Explanation:

When we avoid wastage of water or overuse of then then it is known as conservation of water.

For example, turning off tap when bucket placed below it is filled with water means avoiding wastage of water.

Whereas over flow of water from the bucket is wastage of water.

Thus, we can conclude that using less water is one way to practice water conservation.

Using less water is one way to practice c. conservation. That would come in handy for a drought :D. Hope this helps and have a good day!

In a titration of 0.5 M HCl and an unknown concentration NaOH, 25.0 ml of NaOH was required to completely neutralize 25.0 ml of HCl. What is the concentration of the NaOH?

Answers

When an acid is neutralized by a base, that means moles of H+ = moles of OH-

moles of H+ = 0.5 M * 0.025 L HCl = 0.0125 moles H+

moles of OH- should be equal to 0.0125 moles, so
0.0125 moles = (x) * 0.025 L NaOH

x is the concentration of NaOH, which we want to find.

x = 0.5 M

The correct answer is C) 0.5 M.
