Need fast taking a test plz 20 points
consider the following intermediate chemical equations.
p(s)+ bc (g) 24pc (g)
4pc13(g) →p.(s)+10c12(g)
ah =-2,439kj
ah2 - 3,438 kj
what is the enthalpy of the overall chemical reaction pci (g) → pci,(g)+c12(g)?
o-999 kj
-250. kj
250. kj
999 kj

answer; i believe that the correct answer is (a) potassium(k)

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
