Calculating equilibrium concentrations when the net reaction proceeds in reverse

concentration (m)
[xy] [x] [y]
initial: 0.200 0.300 0.300
change: +x -x -x
equilibrium: 0.200+x 0.300-x 0.300-x

based on a kc value of 0.170 and the data table given, what are the equilibrium concentrations of xy, x, and y, respectively?

The missing component to the table to the right or indicated with orange letters complete the table by filling in the corresponding numbers or symbols

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
