Question

Help! this is my last question remaing

1. For: Cl2 + H2O + As2O3 H3AsO4+ HCl : the coefficient for Cl2 is?

2. An example of a weak electrolye is HCO2 ka = 1.8 x 10-4

True or false

3. balance: KMnO4(aq) + Na2SO3(aq) + KOH MnO2 + Na2SO4(aq) ; the coefficient for KOH is:

(hint: keep MnO2 intact)

4. What is the strongest attractive force CaCl2 can form?

5. Substance A forms dipole-dipole attractions, substance B form dipersion forces. Which will have a higher boiling point?

A. hydrogen bonds B. dipole-dipole C. ionic D. dispersion

1. The coefficient of Cl2 in the given chemical reaction equation would be = 2

2. Weak electrolyte is HCO2 = True

3. Balanced equation,

2KMnO4 + H2O + 3Na2SO3 ---> 2MnO2 + 3Na2SO4 + 2KOH

Coefficient of KOH = 2

4. Strongest attractive force CaCl2 has,

D. dispersion

5. Of the two substance A and B, higher boiling point will be for,

B. A
