For which of the reactions listed below will Gibbs free energy always be. positive?
O A. An exothermic reaction that decreases in entropy
B. An exothermic reaction that increases in entropy
O C. An endothermic reaction that decreases in entropy
D. An endothermic reaction that increases in entropy

I think the answer is: C. An endothermic reaction that decreases in entropy

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
