2Pb(NO3)2 → 2PbO + 4NO2 + 2O2 If 4.6 mol of Pb(NO3)2 is heated, how many moles of NO2 are produced as a result?

0.09 moles of sodium sulfate in 12 ml of solution

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
