Why is photosynthesis an endothermic reaction? the heat content (q) of the reaction is negative. a large amount of energy is released into the surroundings. a large amount of energy is required to activate the reaction. the temperature of the surroundings increases. there is no exchange of energy between the system and the surroundings.

In this synthesis reaction what products will form

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

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?
