Answer: yes
Explanation:Deuterium is a hydrogen isotope with a nucleus containing a neutron and a proton; the nucleus of a protactinium (normal hydrogen) atom consists of just a proton. ... The human body naturally contains deuterium equivalent to about five grams of heavy water, which is harmless.
1.) When a man is engaged to continuous exercise or work, not only his muscles are working but also there is increase in the rate of respiration too. This accelerated rate of respiration and heartbeat provides more oxygen and food to the body. So all the organs and organ systems work in coordination.
2.) I'm sorry that I don't know the answer to your question. The one which I know, I have already written.
Answer:
a) ionic b) polar covalent c) nonpolar covalent
Explanation:
To determine if a bond is covalent or ionic without knowing the electronegativities is to see if it is a metal-nonmetal bond or a nonmetal-nonmetal bond. Metal-nonmetal bonds are ALWAYS ionic, and nonmetal-nonmetal bonds are ALWAYS covalent. A is the metal-nonmetal bond and thus ionic. B & C are both nonmetal-nonmetal bonds and thus covalent.
Polarity:
To determine if a covalent bond is polar or not, we need to see how far apart the elements are away from one another. The further away the elements are from one another the more polar the bond. Nonmetal elements bonded to themselves are ALWAYS nonpolar see compound C. For B, the elements are far apart and are still covalent, so these bonds are polar.
