Using the enthalpy diagram below, determine which of the following is true. 1. The reaction is exothermic
2. The energy difference between reactants and products is greater for the reverse direction than for the forward direction.
3. The combined reactants possess more energy than the combined products.
4. The activation energy in the forward direction is greater than the activation energy in the reverse direction .

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.

Which atom or ion is the largest? 0 a. 0 0 0 0 e. li
