It is known that H2CO3 K1 = 4.3 * 10 ^ - 7, K2 = 5.6 * 10 ^ - 11

It is known that H2CO3 K1 = 4.3 * 10 ^ - 7, K2 = 5.6 * 10 ^ - 11

I think you may want to find the hydrolysis constant of CO32 -. CO32 - + h2ohco3 - + oh-kh1 (CO32 -) = [HCO3 -] * [OH -] / [CO32 -] = {[HCO3 -] * [OH -]} / {[CO32 -] * [H +]} / {[CO32 -] * [H +]} = {[OH -] * [H +]} / {[CO32 -] * [H +]} / {[HCO3 -]

If the values of integer variables s, t, C1, C2, C3 and C4 are all 2, then after executing the statement (s = C1 = = C2) | (t = C3 > C4), the values of S and T are

1 and 0
C1 = = C2 is comparison, returns 1 (true), C3 > C4 returns 0 (false)
So s = 1, t = 0

(17) if there is a definition sentence: int K1 = 10, K2 = 20;
C language
Can, ask for guidance
(17) If there is a definition statement: int K1 = 10, K2 = 20;, after executing the expression (K1 = K1 > K2) & & (K2 = K2 > K1), the values of K1 and K2 are respectively (b). (autumn 11)
A) 0 and 1 b) 0 and 20 C) 10 and 1 D) 10 and 20

The answer is a?

What do K1 and K2 stand for in the water supply and drainage plan?

You should figure out the picture so that others can answer
Check if the K1 pipeline is near the air conditioner stand. If so, it should be the air conditioner condenser
Everyone's drawing habits are different. The standard method is knl-1, but sometimes it is directly marked K1 for convenience
