The major force between ethanol and rubbing alcohol is hydrogen bond. Hydrogen bond are intermolecular force that are weaker than covalent bond but holds atoms together in a molecules. For an hydrogen bond to be formed, a molecule must contain an hydrogen atom that will be bonded to one of the most electronegative element.
Answer:- oxygen.
Explanations:- The electronic configuration is given and we are asked to figure out the electrically neutral atom that will have the electron configuration, 
.
The sum of electrons for this electron configuration is 8. If we look at the periodic table then 8 is the atomic number of oxygen.
So, the electrically neutral atom for the given electron configuration is oxygen.
Answer:
measuring the consumption of the products and the rate of conversion of products to reagents
Explanation:
It must be taken into account that the reaction rate also depends on the presence of a catalyst, since these advance the rate of the reaction.
Thats burning of glucose as fuel in the cells. It generates heat and is an exothermic reaction. In Mitochondria, which act as furnaces, the fuel helps generate heat for the cells of the body.
