Answer:
The correct answer is A. 270L
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. The conditions STP are 1 atm of pressure and 273K of temperature.
We convert the unit of pressure in mmHg into atm:
760mmHg----1 atm
450mmHg---x= (450mmHgx 1 atm)/760mmHg=0,59atm
P1xV1/T1= P2xV2/T2
V2=((P1xV1/T1)xT2)/P2
V2=((0,59atmx500L/300K)x273K)/1 atm=<em>269,407 L</em>
Answer : The balanced chemical reaction will be,
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
Glucose on oxidation gives carbon dioxide and water as a product and some amount of energy is also released.
The balanced chemical reaction will be,
In this reaction, glucose molecule shows oxidation due to change in oxidation state of carbon from (0) to (+4) and oxygen molecule shows reduction due to change in oxidation state of oxygen from (0) to (-2).
