The reaction that you will be investigating is the reaction that occurs when an alka-seltzer tablet is placed into a given amount of water.
c(graphite) + o2(g) → co2(g) + 94.05 kcal
c(diamond) + o2(g) → co2(g) + 94.50 kcal
what could you infer from the information given above?
-the enthalpy of co2is greater than the reactants.
-e2- e1is negative.
-graphite and diamond have equal enthalpy.
-diamond must have lower internal energy.

How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?

Which property of a rock remains unchanged by mechanical weathering? a. total surface area b. size and shape c. mineral composition d. sharpness

The table lists the lattice energies of some compounds.compoundlattice energy (kj/mol)lif            –1,036licl            –853naf            –923kf            –821nacl            –786which statement about crystal lattice energy is  best  supported by the information in the table? the lattice energy increases as cations get smaller, as shown by lif and kf.the lattice energy increases as the cations get larger, as shown by lif and licl.the lattice energy decreases as cations get smaller, as shown by nacl and naf.the lattice energy decreases as the cations get smaller, as shown by naf and kf.
