A) oo B) 0 0) 1 D) -1 B) It cannot be determined without concentrations 9) ldenlify what type of solid each of the following is? A) NH4N03 B) Sio2 O copper 10) 10) Which of the following is a WEAK acid? D) HNO3 E) H2SO4 A) HCO2H 11) 11) Consider a reaction that has positive AH and a positive AS. Which of the following statements b TRUE A) This reaction will be spontancous at all temperataurers B) This reaction will be nonspontaneous at all temperatures. Q. This reaction will be spontaneous only at high temperatures. D) This reaction will be nonspontaneous only at high temperatures B) It is not possible to determine without more infornation. 12) Choose the situation below that would result in an exothermic Solution. 12) A) When /AHlattice

Explanation / Answer

(8)

Since the reaction quotient is a ratio of conc of products to the reactants, so a mixture which contains only reactants will have Q = 0.

(9)

(a) Ionic

(b) Covalent

(c) Metallic

(d) Polar covelent

(10)

HCO2H is a weak acid because it is an organic acid.

Hope this helps !
