Identify the equations that show ionization. Check all that apply.
So
O NaCl(s) → Na+ (aq) + Cl(aq)
O HCl(g)+H20(1) → H30* (aq) + Cr (aq)
0 02(g) + O2(aq)
0 CO2(9)+2H20(1) ► HCO3(aq) +H30* (aq)
O CaCl2(s) → Ca2+ (aq) +2Cr (aq)
DONE

Atrain travels 74 kilometers in 3 hours, and then 81 kilometers in 5 hours. what is its average speed?

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)
