A pudding would be considered as solid since the molecules are in an ordered state and they are close to each other which gives definite shape and volume for the pudding. This is also true for the bucketful of sand. Hope this answers the question.
Answer: 2.51 moles of oxygen is consumed
Explanation:
Exothermic reaction : It is a type of chemical reaction where the energy is released into the surrounding. In the exothermic reaction, the energy of reactant are more than the energy of product.
In exothermic reaction, the change in enthalpy is, negative
The balanced chemical reaction is:
According to stoichiometry:
When 1 mole of oxygen is consumed , energy released = 285.8 kJ
285.8 kJ of energy is evolved when oxygen consumed = 1 mol
Thus whn 717.4 kJ of energy is evolved when oxygen consumed = moles
2.51 moles of oxygen is consumed
A p53 gene is the one responsible for preventing a cancer from evolving in an individual's body, it is also a tumor suppressor. If a p53 is damaged, then it could result to cancer, spreading in the entire body and it can also arises tumor growth. So the correct letter of the answer above the following is letter A.
