In what way did rannan make an error in his scientific process? he should not use a systemic process. he should not use his opinions as evidence. he should not make observations. he should not use multiple steps in his process.

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.)

Which of these is a physical property
