When solutions of KCl and Pb(NO3) 2 are mixed, a precipitate forms. Which of the following is the balanced equation for the double replacement reaction that occurs?

A) KCl(aq) + Pb(NO3)2(aq) → KNO3(aq) + PbCl2(S)

B) KCl(aq) + Pb(NO3)2(aq) → KNO3(aq) + PbCl(s)

C) 2KCI (aq) + Pb(NO3)2(aq) + 2 KNO3(aq) + PbCl2 (s)

D) KNO3(aq) + PbCl2(s) → KCl(aq) + Pb(NO3)2(aq)

E) K+ (aq) + NO3(aq) → KNO3(aq)

Agas at 155 kpa and standard temperature has an initial volume of 1.00 l. the pressure of the gas rises to 500 kpa as the temperature also rises to 135°c. what is the new volume? 2.16 l 0.463 l 0.207 l 4.82 l

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
