Copper was first heated up in a crucible with sulfur to form copper sulfide. So if there is enough oxygen present to form copper (II) oxide, will CuS break apart to form copper oxide in the present of oxygen as well as sulfur oxide? or will it not react at all because all the copper had already reacted with sulfur?
However if all the copper did not reacted with sulfur, then oxygen should be able to react with the copper to form copper oxide right?
write the ground state electron configuration( using molecular orbital theory) for o2 and show that it is paramagnetic.
Which statement best desrcibes the energy change as bonds are formed and broken in this reaction ?
Consider a glass of 262 mL of water at 28°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved.
Why does the temperature 25 degrees Celsius have three significant figures and the temperature of -196 degrees Celsius have only two significant figures
One way of solving systems of linear equations is by adding a multiple of one equation to the other. The multiplier for one equation is chosen so that one of the two variables will cancel out in the sum
