What type of hydrogen bonds form between nitrogenous bases?

1 answer:

6 0

Weak Bonds
These bases contain Nitrogen and these create a twofold strand of DNA through not so strong hydrogen bonds. The nitrogen bases, notwithstanding, have particular shapes and hydrogen bond properties so guanine and cytosine just bond with each other, while adenine and thymine additionally bond only. This matching off of the nitrogen bases is called complementarity. All together for hydrogen clinging to happen by any means, a hydrogen bond benefactor must have a corresponding hydrogen bond acceptor in the base opposite it.

If 0.138g of cyclohexene (c6h10) was obtained from 0.240g of cyclohexanol (c6h120), what is the percentage yield of cyclohexene?

tino4ka555 [31]

<span>Given in the question- 1 mole of cyclohexanol = > 1 mole of cyclohexene Molar mass 100.16 g/mol moles of cyclohexanol = .240 / 100.16= 0.002396 moles Molar mass 82.143 g/mol moles of cyclohexene formed @100 % yield = 0.002396 Molar mass 82.143 g/mol mass of cyclohexene @ 100 % = .002396 x 82.143 = 0.197g bur we have .138g so % yield = .138 / .197 = 70.0 % Ans- 70 percentage yield of cyclohexene.</span>

Lena [83]

Answer:

a).

$2 \: moles \: of \: ethane \: react \: with \: 7 \: moles \: of \: oxygen \\ 24 \: moles \: react \: with \: ( \frac{24 \times 7}{2} ) \: moles \\ = 84 \: moles$

b).

$2 \: moles \: react \: with \: 7 \: moles \\ ( \frac{12 \times 2}{7} ) \: moles \: react \: with \: 12 \: moles \\ = 3 .43 \: moles \\ 1 \: mole \: weighs \: 30 \: g \\ 3.43 \: moles \: weigh \: (3.43 \times 30) \\ = 102.9 \: g$

c).

746.7 g

The term “flat bone” is somewhat of a misnomer because, although a flat bone is typically thin, it is also often curved. Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs.
