Answer:
3.09kg
Explanation:
First, let us write a balanced equation for the reaction. This is illustrated below:
2C8H18 + 25O2 —> 16CO2 + 18H2O
Molar Mass of C8H18 = (12x8) + (18x1) = 96 + 18 = 114g/mol
Mass of C8H18 from the balanced equation = 2 x 114 = 228g
Converting 228g of C8H18 to kg, we obtained:
228/1000 = 0.228kg
Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol
Mass of CO2 from the balanced equation = 16 x 44 = 704g
Converting 704g of CO2 to kg, we obtained:
704/1000 = 0.704kg
From the equation,
0.228kg of C8H18 produced 0.704kg of CO2.
Therefore, 1kg of C8H18 will produce = 0.704/0.228 = 3.09kg of CO2
Ionic bonds are formed due to tendency of a metal to donate an electron and tendency of non metal to gain an electron.
Answer:
Hydrolysis
Explanation:
The phosphate groups in an ATP molecule are joined forming an ester group. Esters can be formed when an alcohol (-OH) bonds with an acid (-COOH, or, in the case of phosphoric acid, 
). When this bonding occurs, the two molecules together lose a molecule of water, because the alcohol loses the hydroxyl and the acid loses an hydrogen, and the three atoms combine to form water. All the chemical bonds that are formed with the loss of a water molecule can also be broken using water, and this reaction is called hydrolysis.
A) Certain electrons in the dye molecule move to a higher energy level, with the difference in energy between the lower and higher energy levels being the same as the energy of the absorbed photons.
Explanation:
The reason behind the photonsWhen UV photon or a photon of visible light is absorbed by an atom then the summation whole of energy of that particular photon gets all excited to a higher energy level. The following movement of an electron to a higher energy level from a lower energy level is called as a transition. A successful transition occurs only in that condition when the energy of the photons which gets absorbed should be greater than or equal to the difference in energy between the underlying energy levels. also,we know that once the electron is being excited to a higher energy level, it becomes more unstable for a fact we know that electron becomes stable only when iot ios grounded or in groud state. As such, the electron will quickly fall back down to the lower energy level and hence it emits a photon with an energy equal to the difference in energy levels.
this explains best about the phenemenon of phtons of visible light being absorbed by dye molecules
