1. Calculate the pH and pOH of each of the
following acidic solutions:
(a) 0.0092 M HOCI ([H+] = 1.8 X 10 M)
(b) 0.0810 M HCN (TH+] = 6 X 10 M)
(c) 0.992 M HC204- (percent ionization is 2.5%)
(d) 0.138 M CH3CO2H(percent ionization is 1.2%)

What is the volume occupied by 10.0 dm3 of gas at standard pressure after it has been compressedat constant temputure to 500.0 kpa?

Balance and in which category does it fit in? single or double displacement or synthesis or decomposition? (a) k2 o → k + o2 (b) na + i2 → nai (c) cu(no3 )2 + naoh → cu(oh)2 + nano3 (d) kclo3 → kcl + o2 (e) ca(no3 )2 + hbr → cabr2 + hno3 (f) sn(oh)2 → sno + h2 o (g) p4 + n2 o → p4 o6 + n2 (h) fe + al2 (so4 )3 → feso4 + al (i) alcl3 + na2 co3 → al2 (co3 )3 + nacl (j) c3 h6 + o2 → co2 + h2 o
