Dr. Haxton says the O-O bond is polar and the C-C bond is nonpolar. A good student would say ...
a.No, both bonds are highly polar.
b.Yes. O attracts electrons more strongly than C.
c.Right! O is electronegative, so O2 is polar.
d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.
e.No way. C is more electronegative than O.
Answer: d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.
Explanation:
Often when O and H are present in the substance at (opposite) ends (of the electronegativity scale), the polarity observed is very large, we can safely say the substance have a polar bond in it.
Answer:
carbohydrate for quick energy boost
protein to grow healthy hair
carbohydrate to race tomorrow
proteins to get bigger muscles
Explanation
carbohydrates contain glucose that can be broken down through glycolysis to provide energy in form of ATP. proteins are the main body building organic compounds. Keratin a type of protein is required for healthy hair growth. muscles also require proteins to get bigger.
Answer:
C
Explanation:
A. Since
B. Because
C. Although
D. For example
<em>Zebra mussels have been known to have a lifespan of six or seven years in the past but recent discoveries have shown that their average lifespan now ranges between one to two years. Hence, the correct word to fill in the gap would be 'Although'. </em>
<em>The correct option is C</em>
