A coefficient is the number or letter before the variable. The variable is the unknown value.
One molecule of N2O4 contains
two nitrogen
four oxygen
Every compound or element has a fixed number of molecules
per mole. This is given by the Avogadros number which is about 6.022 x 10^23
molecules per mole. Therefore:
molecules = 2.50 moles * (6.022 x 10^23 molecules / mole)
<span>molecules = 1.5055 x 10^24 molecules of SO2</span>
Answer:
3rd or 4th answer is correct
Answer:
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
