calculate the heat given off when 177g of copper cools from 155 C to 23 C. The specific heat of copper is 0.385 J/g C

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.

Which fact represents evidence for the big bang theory?

Answer explain why it is not possible to deduce a complete order of reactivity.
