Oxygen difluoride is an unstable molecule that reacts readily with water. calculate the bond energy of the o–f bond using the standard enthalpy of reaction and the bond energy data provided. just enter a number (no units). of2(g) + h2o(g) \longrightarrow⟶ o=o(g) + 2hf(g) \deltaδh° = –318 kj bond: o–h o=o h–f bond energy (kj/mol): 467 498 565

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder

Match the mixture with the substance// i really need on this guys (it’s a pic btw)
