There exist electrovalent bonding the compound MgS . In electrovalent bonding, there is a transfer of electron from the metal to non-metal.

You are watching: In the compound mgs, the sulfide ion has

Magnesium atom has an atomic number 12 and also its electron construction is 2,8,2

Sulfur atom , a non-metal has actually atomic number of 16 and also its electron construction = 2,8,6

This way that magnesium together a metal needs to loose two electrons from its valence covering to attain its steady structure.Also sulfur calls for two an ext electron to achieve its octet structure.

Hence a move of electrons will take location from magnesium atom come sulfur atom, sulfur acquiring two electrons.



2. Lost two electrons.

Explanation:

Equation that the reaction:

Mg2+ + S2- --> MgS

Therefore, sulphur ion is oxidised if magnesium ion is reduced. In various other words, Magnesium ion benefit 2 electrons while sulphur ion loser 2 electrons.



1. Sunlight is important for the varied life on earth. Sunlight provides energy to photosynthetic organisms by providing a. The power necessary to strength the rearrangement of chemical bonds in h2o and also co2The key energy resource for photosynthesis originates from the sunlight. The plant has actually the capability to readjust the energy from sunlight into chemical power that was stored by developing glucose.2. Lungs are to breathing as d.mitochondria are to cellular respiration.Lungs breathe to take it oxygen from the environment to accommodate the aerobic to move respiration. The last two procedure of to move respiration will happen in mitochondria. Mitochondria is vital organ due to the fact that it connected in the electron carry thayieldsld highest ATP of moving respiration.3. Once a auto engine burns gasoline, the results of the reaction are similar to as soon as cells burn glucose. Both reactions relax carbon dioxide and water. In cells, the chemical energy in food is converted to atp and also heat. In a moving car, the chemical power in gasoline is converted to kinetic energy and also heat.The reaction will use chemical energy stored in the gasoline/glucose that become the reactant. The chemical energy is offered to move the car/muscle, which provides the kinetic energy. Warm should it is in the side product which will certainly make the car/body warmer throughout exercise.4. Offered the fairly modest number of calories burned by anything but the most vigorous activities, why can world consume over 2,000 kilocalories a day, yet keep a healthy body weight?a.most the the power consumed in food is spent preserving the body"s functions, so just a portion of food power needs to be melted in exercise.The body demands the power to execute their everyday function, referred to as basal metabolic rate. If the energy from spend food is same or less than BMR, over there is no excess power that will certainly be stored together fat.5. A molecule that functions as the electron donor in a oxidation reaction a.loses electrons and becomes reduced.Oxygen is highly reactive due to the fact that it has actually a tendency to take/receive electrons from various other substance. Since oxygen loser it electrons, that is become reduced. A molecule the reacts v oxygen is the electron donor. The donor will offer electron and those who lose the electron will be oxidized.6. In cellular respiration, glucose loses electrons, whereas oxygen gains electrons.The carbon atom of glucose will lose electrons in cellular respiration and also become carbon dioxide. The electron comes from the oxygen i m sorry will become the water. This reaction will develop ATP. 7. Oxidative phosphorylation can not happen without glycolysis and also the citric acid cycle, because these two stages it is provided the electrons required for the electron carry chain.Oxidative phosphorylation produces many of the ATP indigenous cellular respiration. But it will need electrons indigenous the electron deliver chain. The electrons will be noted by NADH and FADH2 which will certainly be formed in the glycolysis, transition and Krebs cycle.8. glycolysis is the only stage of moving respiration that requires ATP to make ATP.When glycolysis procedure is simplified, the doesn"t seem to require ATP because it produces 2 an ext ATP than it uses. But there is 2 reaction in glycolysis referred to as phosphate ester synthesis which an endothermic reaction. This reaction will need ATP because that hydrolysis.9. Us inhale o2 and also we exhale co2. Carbon dioxide is produced b.in the reaction that creates acetyl coa (coenzyme a) native pyruvateAfter glycolysis, one molecule the glucose will produce two pyruvates. Every one pyruvate will create one acetyl coa, one NADH, and also one carbon dioxide in shift reaction. Carbon dioxide also produced in Krebs cycle(citric acid cycle).10. A scientist wants to examine the enzymes of the citric mountain cycle in eukaryotic bio cells. What part of the cell would certainly she usage as a resource of this enzymes?c.mitochondrial matrixThe reaction of the citric mountain cycle happens in the matrix of mitochondrial and also its inner membrane. A prokaryotes organism the doesn"t have actually mitochondria will need to it in the cytosol and the cabinet surface. 11. Each turn of the citric mountain cycle generates one ATP and also four added energy-rich molecules: 3 NADH and 1 FADH2.NADH and FADH could undergo Oxidative phosphorylation which will give much much more ATP 보다 glycolysis or citric acid cycle combined. Every NADH can produce 3 ATP while every FADH2 can produce 2 ATP. NADH can produce much more ATP since it tie with complex I while FADH2 tie to facility II.

1.Decomposition i think2.boiling3.It is a solid at room temperature and pressure.4.The base donates a hydrogen ion.5.That reasons the oxidation of an additional element6.MnO27.When a substance is reduced, electrons are lost.8.True ns think9.False10.TrueHope these space correct

alternative (c) is the exactly answer.

Explanation:

The provided reaction equation is together follows.

*

The oxidation-reduction half reactions will certainly be together follows.

Oxidation :

Reduction:

*

By balancing the above fifty percent reactions, oxidation-half reaction will certainly be as follows.

*

Whereas reduction-half reaction will stay the same.

Hence, it mirrors that every copper atom is losing one electron to combine with a sulfur atom.

Therefore, we deserve to conclude the each copper atom loser one (1) electron.



B) shed 3 electrons

Explanation:

I i think you mean Al⁺³. That way the atom loses 3 electrons. Electrons have actually a an unfavorable charge, so losing them gives the ion an overall positive charge.

C) reduced because electrons are got which produces reduced water

Explanation:

The electron transport chain (ETC) entails a series of chemistry reaction based upon the reduction and also oxidation of molecules. According to the question, the electrons that leave the chain combine with a last electron acceptor referred to as Oxygen. This reaction is a palliation reaction because oxygen profit electrons.

The gaining of electrons by Oxygen to reduce it to water (H2O). Hence, water is claimed to be reduced due to the fact that electrons are got by oxygen to develop a decreased form, referred to as water.
