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
Answer is A
You never run down adjacent to you spinal cord and bones. That’s where they are the most protected. There are also holes in the pelvis bone for nerves to pass through
Answer:
No we can’t cover the earth with one mole of pennies
Explanation:
We can’t cover the earth with one mole of pennies due to the fact that making this possible will require the flattening and extra expansion before it covers the whole surface.
The extra expansion and flattening with result in the loss of intermolecular forces and won’t remain as a solid and form other states of matter which won’t be able to cover the surface.
Answer:
The standard cell potential of the reaction is 0.78 Volts.
Explanation:
Reduction at cathode :
Reduction potential of 
to Cu=
Oxidation at anode:
Reduction potential of 
to Fe=
To calculate the 
of the reaction, we use the equation:
Putting values in above equation, we get:
The standard cell potential of the reaction is 0.78 Volts.
