Answer:
С. form chains or rings by bonding to itself and other atoms.
Explanation:
Carbon is an element in group 4 of the periodic table with unique bonding properties. Carbon posseses 4 valence electrons in its outer shell. This enables carbon to form covalent bonds with the atoms of other elements e.g. nitrogen, phosphorus, oxygen, hydrogen etc.
Carbon can also combine covalently with other carbon atoms i.e. C-C to form long chains and rings in a process called CATENATION. This unique property of carbon makes it the only element that can form so many different compounds.
A negativley charged ion is the answer
Answer:
Is B, it is B because you don't need arrows on it.
Specific heat capacity of any substance comes with the unit : J/(g*degree C)
for molar capacity , change gram -> moles unit ( J / moles * degree C)
4.18 J / mol - degree C
H = 1.01 g * 2 = 2.02 g
O = 16 g
2.02 + 16 = 18.02 g
Now :- 4.18 J / mol- degree C) * 18.02 / 1 mole H2O
molar heat = 75.3 J / mol - degree C
