Predict, then balance. if no reaction occurs write NR. Please show work. 1. combustion: CH3COOH + O2
2. single replacement: Zn + Au(NO2)2
3. double replacement Bas+ PtCI2

Which of the following is most likely true about water in chemical solutions?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Ab c or d ? i’m not sure what the answer is
