Answer:

Bias can cause the results of a scientific study to be disproportionately weighted in favor of one result or group of subjects. This can cause misunderstandings of natural processes that may make conclusions drawn from the data unreliable.

Artificial products, medicines, and fertilizers are examples of chemistry discoveries that have had the greatest impact on the modern world. Polymer discovery has resulted in all the plastics and synthetic fabrics that surround us today.

Understanding how the properties of substances are related to their molecular structures allows chemists to design new molecules and materials with the desired properties, as well as develop or invent new types of transformations for carrying out the syntheses of these substances.

Chemistry is used in almost every aspect of today's automobiles, from the exterior paint, bumpers, and headlights to the interior seats, dashboard components, and seatbelts and airbags that protect passengers.

To name a few, industrial applications of chemistry have a direct impact on our daily lives: what we eat, what we wear, how we travel, the technology we use, how we treat illnesses, and how we get electricity. Chemistry research is constantly deepening our understanding and leading to new discoveries.

Answer: I believe you may have meant "ionization energy?" Yes, for a neutral element this is a measure of the energy required to remove a valence electron.

Explanation: See above.

By definition, The energy required for the complete removal of 1 mol of electrons from 1 mole of gaseous atoms or ions is called Ionization energy. For a neutral element this energy is a measure of how easily the element forms an ion with a charge.

The electrons are attracted to the nucleus and it is necessary to provide energy to start them.

Ionization energy is the energy required to remove an electron from a gaseous atom, isolated and in a ground state. The electrons in the last shell, which are the weakest attracted to the nucleus, are always lost. In this way the neutral atom becomes a gaseous cation (positively charged ion).

The further away the electron is from the nucleus, the easier it is to remove it, that is, the less energy is needed.

Finally:

The energy required for the complete removal of 1 mol of electrons from 1 mole of gaseous atoms or ions is called Ionization energy. For a neutral element this energy is a measure of how easily the element forms an ion with a charge.

Answer:

So, that if you put 100 mL of 30 degree water in a beaker, you could add up to 220 grams of sugar and it would eventually dissolve. In other words, that mass of sugar should dissolve in 100 mL of water to make a solution that is just saturated.

Explanation:

Answer:

7 meters per second directly toward the reef

Explanation:

The barracuda swam for 8 seconds, and in 1/4 of that time it swam 14 meters, so:

8•1/4 = 2

The barracuda swam 14 meters in 2 seconds

Now, the velocity is the travelled distance divided by time, so:

14/2 = 7 meters per second

The position of element A is first group i.e. alkali metals whereas element B belongs to other groups.

It is because alkali metals reacts violently with water that leads to little explosion and also produced hydrogen gas while on the other hand, element B belongs to next groups in the periodic table. The reactivity of element A is higher than element B due to lack of one electron in the outermost shell which make it highly reactive as compared to element B which is less reactive in nature.

Explanation:

because nuclear charge ( no. of protons) increases

Answer:

I don't know if you can directly prove it with evidence if you haven't observed it but you can maybe take an educated guess by the aftermath of it?

For example, you see a burnt log. At this time, people don't know what fire is. After we study the log, we could see that it takes extreme temperature in order to burn the log and that would help people see that there is a force like fire that can cause this. In a way, finding out that extreme temperatures burns stuff is another step closer to the discovery and proof of fire
