The initial temperature of a 626 g plate of zinc is 25.0°C. How many total kJ of heat energy will be needed to heat the metal to its melting point of 420°C? [ c(Zn) = 0.386 J/gC°].

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?

Which is true of a liquid? it has a definite volume but not a definite mass.it has a definite mass but not a definite volume.it has a definite volume but not a definite shape.it has a definite shape but not a definite volume.

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