What is the standard free energy change (in kilojoules) for the following reaction? 2SnO2(s)→2SnO(s)+O2(g) ΔG∘298,SnO2(s)ΔG∘298,SnO(s)=−515.8k Jmol=−256.9kJmol

no

explanation:

go away, people want answers, not to hook up

clouds form

solid ice forms on leaves.

water droplets form on grass.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
