What would be the effect if all of the copper reacted but enough oxygen was present to form Copper (II) Oxide?(If copper is reacting with sulfur in a heated crucible. This is a question on my lab.)
heating copper wire, in a crucible with melted sulfur usually produces Copper (I) sulfide, Cu2S whose molar mass is 159.2 g/mol that's 2 moles of copper & 65.4 g/mol each ... which is 131 grams of copper producing 159 grams of Cu2S converting copper, at 65.4 g/mole, into Copper (II) oxide, whose molar mass is 79.5 g/mole doubling those: that is 131 grams of copper producing 159 grams of Cu0 you will not notice a mathmatical difference in the calculations whether you produce all Cu2S or if it is contaminated with some CuO
it is assets you do in center college for homework. to do this, seem at a periodic table. Iook at what share valence electrons each has to confirm its charge. To stability an equation, purely have diverse quantities of each component to make the popular cahrge 0. Or, in the journey that your balancin an equation, you may desire to stability the subscripts and coefficients.
