1. What is the approximate % ionization of a 0.010 M HNO2 (aq) solution)? (Ka = 4.0x10^-4) 2. The pH of a solution made by combining 150.0 mL of 0.10 M KOH with 50.0 mL of 0.20 M HBr is closest to which of the following?

4. absorption has the highest risk of overdose due to increased potency. a. rectal b. oral c. transdermal d. intranasal

What reaction is taking place? 02 + c3h8 = h20 + co2

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)
