The burning of glucose in presence of oxygen is called as combustion
The balanced reaction is
C6H12O6 + 6O2 ---> 6CO2 + 6H2O
Thus for each mole of glucose we need six moles of oxygen molecules
molar mass of glucose is 180g / mole
The moles of glucose present = mass / molar mass = 180 / 180 = 1 mole
The moles of oxygen present = mass / molar mass = 192 / 32 = 6 moles
Thus the reaction will go to completion and one mole of glucose will react with six moles of O2 to give six moles of CO2 and six moles of H2O
Mass of CO2 produced = moles X molar mass = 6 x 44 = 264 g
Mass of H2O produced = moles X molar mass = 6 x 18 = 108 g
<span>Ca^(2+). Calcium is an alkaline earth metal with an atomic number of 20. Its electronic configuration is (2, 8, 8, 2). From the electronic configuration it would be observed that calcium has two valence electrons. Calcium shares these two electrons with non metals like sulphur in an ionic bond to obtain an outer shell which is full octet. Let me use Sulphur. When calcium gives out its two valence electrons its electronic configuration becomes (2, 8, 8) thereby obtaining a stable out shell and the calcium ion becomes Ca^(2+). The sulphur also obtains a stable octet because it has 6 valence electron initially.</span>
