In an experiment, a 25.0-g sample of mercury is reacted with 5.0 g of oxygen. At the end of the reaction 6.2 g of mercury and 3.5 g of oxygen were found unreacted. According to the law of conservation of mass, how many grams of mercury oxide are formed? (Assume mercury oxide in the only product in this reaction.) show your answer

The answer options is d

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
