Mr. Smith wanted to see if the color of light shined on a plant had an effect on the number of leaves it had. He gathered 2 groups of the same species of plants, gave them the same amount of water, and did the test for the same amount of time. On one group of plants, he used white light. In the second group, he changed the light to red. What is the control group?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
