The amino and carboxyl functional groups tend to form bases and acids by attracting or droppingA) an electron. B) a neutron. C) a proton and an electron. D) a neutron and a proton

Explanation:

When a substance or chemical specie accepts a proton then an acid is formed. Whereas is a substance or chemical specie tends to lose a proton then a base is formed.

Chemical formula of amino group is and it is able to lose a proton to form R-NH-R'. When it tends to gain a proton the it form R-NH_{3} compound.

Chemical formula of carboxylic group is -COOH. When it loses a proton it forms ion and whenit gains an electron then it forms .

Therefore, we can conclude that the amino and carboxyl functional groups tend to form bases and acids by attracting or dropping a proton.

current flows in a wire

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
