A 0.6 g piece of copper is heated and fashioned into a bracelet. The amount of energy transferred by heat to the copper is 62,100 J. If the specific heat of copper is 390 J/g 0C, what is the change of the copper's temperature?

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

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