vekshin1

Answer:

Hello

The answer is 18,7(b)

Explanation:we don't know the value of o² so at first we should put (x)instead of gr of o²and then write 1molO²/32grO²×2mol SO²/3mol O²×64gr SO²/1molSO²=25 gr SO².and then just find the value of (x).

The partial Lewis structure that follows is for a hydrocarbon molecule. In the full Lewis structure, each carbon atom satisfies
ahrayia [7]

Answer:

C-C> C=C> C\equiv C

So, 2 > 1 > 3

Explanation:

Carbon is a  non-metal and has 6 electrons. In the excited state, it contains 4 electrons in its outermost shell and so 4 electrons take place in covalent bond formation. In a molecule , 2 carbon atoms can be bound by a single bond, the double bond and by a triple bond. Since the bond length of C\equiv C is 120 pm, the bond length of C=C is 134 pm and the bond length of C-C is 154 pm. Thus in the given compound, C= C-C\equiv C , in which C= C is labeled as 1,  C-C is labeled as 2 and C\equiv C is labeled as 3. So the bond length of carbon-carbon bonds in the molecule, in decreasing order is 2 > 1  >3.
