An electron carries a negative power to the atom. in each atom, the amount of protons and electrons are usually evened out so the atom is stable. the electrons of an atom are also found on the outside ring of an atom, unlike protons and neutrons, which are inside the atom. glad to help! :)

Dmitry [639]

<em>Answer:</em>

  • It behaves as the electron donar. Its is correct one

<em>Definition of lewis base:</em>

  • Lewis base is a such a substance which donate pair of electron to Lewis acid.

<em>Example:</em>

                                       H3N +  BF3  ⇒   H3N---≥BF3

  • Ammonia is a lewis base while boron trifluride is lewis acid.

<em>Condition</em>

  • There should be lone pair of electron

Q3. A student wanted to make blue copper sulfate crystals from green copper carbonate powder
CaHeK987 [17]

Heat the sulfuric acid solution and adding copper carbonate in it.

<h3>Improvement require in this experiment</h3>

The method could be improved by heating sulfuric acid solution and add copper carbonate into the solution of sulfuric acid. Add the copper carbonate until it is present in excess amount. After that filter the extra amount of copper carbonate so in this way the blue copper sulfate crystals are produced.

What rate of reaction can be measured in the dark by determining the amount of oxygen gas consumed in a period of time?
Hatshy [7]

The rate of reaction that can be measured in the dark by determining the amount of oxygen gas consumed in a period of time is the rate of respiration.

Why?

Plants can undergo two types of reactions involving oxygen:

  1. <u>Photosynthesis: </u>In this type of reaction, plants use energy from light to synthesize glucose. The chemical reaction for photosynthesis is: 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂, and this reaction produces oxygen gas in the presence of light, that means that to measure the rate of photsynthesis, you'll need to measure the amount of oxgen gas <u>produced</u> in a period of time.
  2. <u>Respiration:</u> In this type of reaction, plants convert the energy stored in the chemical bonds of molecules such as glucose to obtain energy. The chemical reaction for respiration is: C₆H₁₂O + 6O₂ → 6H₂O + 6CO₂, since this reaction consumes oxygen gas in the dark, that means that to measure the rate of respiration, you'll need to measure the amount of oxygen gas <u>consumed</u> in a period of time.

Have a nice day!
