To draw a Lewis structure for a
polyatomic ion, begin by
calculating A, the available
electrons, and N, the needed
electrons.
What is N for ClO3^- the chlorate ion?

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.
