Answer:

A silicone atom shares an electron pair with each oxygen atom

Explanation:

Because the silicone dioxide molecule has one silicone atom:two oxygen atoms....

Hence...since silicone has four electrons in the outter shell..which are used for bonding...each oxygen atom shares two electrons(an electron pair) with the silicone atom...so as to fill the outter shell of the oxygen atom

What happens to the ratio of oxygenated hbo2(aq) to deoxygenated hb(aq), i.e. , when there is a high pressure of oxygen, po2(g),
maw [93]

The chemical equilibrium representing the reaction of hemoglobin with oxygen is,

Hb (aq) + O_{2}(g)  HbO_{2}(aq)

In the lungs, where the partial pressure of oxygen is high, the above equilibrium shifts towards the products according to the LeChattelier's principle, as the pressure of one of the reactants is increased. This leads to the formation of more oxyhemoglobin.

In the cells, where the partial pressure of oxygen is low, the equilibrium shifts towards left that is hemoglobin.

Therefore the ratio of oxyhemoglobin to hemoglobin increases as the partial pressure of oxygen is high in the lungs.

1. Why is carbon dioxide a gas at low temperatures at mars
wlad13 [49]

1. carbon dioxide is a gas at low temperatures at mars because in the oxidizing environment organic compounds are oxidized to form carbon dioxide.

2. The 1 electron in outermost shell of Na is shared with 7 electrons of outermost shell of chlorine giving neutral charge on compound.

3. Electrostatic force of attraction is between the metal and non-metal.

4. When metal and non metal exchange electrons to form a neutral or no charge compound it is said to have form ionic bonds.

Explanation:

1. Temperature at Mars is very low -80 Fahrenheit  (-60 degrees) because water is not present in the planet. Carbon dioxide is abundant in Mars. The atmosphere is oxidizing at Mars which oxidizes the organic compounds and forms carbon dioxide.

2. NaCl combines by sharing of electrons forming ionic bonding. Different atoms of the different element share electrons to form ionic bonds. Such bond is formed when electrons is transferred between the atoms. In the NaCl, Na has 1 electron (electropositive) in its outer shell and chlorine has 7 electrons (electronegative). Both share the electrons getting their octet complete and a neutral charge on the compound formed.

3. Electrostatic force of attraction is between the metal and non-metal when bond is formed. The ionic bonds is formed between metal and non metals when electron exchange takes place. The electrostatic force is the attraction between two opposite charges on the ion.

4. When a metal and non metal exchange electrons in which metal is electropositive and non metal is electronegative the bonds form is called ionic bond. The electron is transferred from metal to non metal and thus giving neutral charge on the compound i.e. the outer shell has its octet complete.

Why does increasing the temperature of two reactants in solution make a
gogolik [260]
The two molecules will only react if they have enough energy. By heating the mixture, you are raising the energy levels of the molecules involved in the reaction. Increasing temperature also means the molecules are moving around faster and will therefore "bump" into each other more often.

What is the difference between elements, mixtures, and compounds?
MAXImum [283]

Answer:

If it is pure, the substance is either an element or a compound. If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
