Answer:

hello . proton:17 electron:18 neutron :18

Explanation:

it's obvious and you must memorise that Cl has 17 protons .

because it has one negative so electrons which are negative should be one more than protons I mean 18

neutron doesn't need to look at it here

electron shows the answer.

hope u understand

if u have any questions don't hesitate to ask.

Consider the given acid ionization constants. identify the strongest conjugate base.

The question is incomplete. Complete question is:
<span>Consider the given acid ionization constants. identify the strongest conjugate base.
</span>HNO2(aq) 4.6×10−4
HCHO2(aq) 1.8×10−4
HClO(aq) 2.9×10−8
HCN(aq) 4.9×10−10
.........................................................................................................................
Correct Answer: option 4: HCN(aq) 4.9×10−10

Reason:
According to Lowry and Bronsted theory of acid and base. Stronger the acid, weaker will be the conjugate base.

In present case, ionization constant is highest of HCN i.e. 4.9× $10^{-10}$ . This signifies that, it is the strongest acid. Hence, conjugate base associated with this acid (i.e. $CN^{-}$ ) is the weakest.
