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

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o

The following is a blank kkkxxx idk ttyl
