Gravity. The rock is being pushed down and you are counteracting that force with a crowbar pushing it upward.
Answer:
3) H-O
Explanation:
because oxygen and hydrogen have very high difference in electronegativity
Options are as follow,
<span>A) Covalent bonds are formed by metals and nonmetals.
B) Covalent bonds are are typical of carbon compounds.
C) Covalent bonds are created by the attractions between oppositely charged ions.
D) Covalent bonds break apart when dissolved in water and allow for the conduction of electricity.
</span><span>Answer:
Covalent bonds are formed by mutual sharing of electrons between two atoms of having electronegativity difference less than 1.7. Among given options only option-B seems correct.
Explanation:
Carbon containing compounds are almost covalent in nature. Majority of organic compounds are made up of carbon, hydrogen, oxygen and nitrogen. And carbon makes covalent bonds with all these atoms.
Result:
</span>Option-B is correct.
Explanation:
the further down the group you go, the larger the radius becomes. its caused by the amount of electrons needed to equal out the charge of the nucleus
