I answered as many as I could but can someone double check my answers and help me with the rest? 1. Example Bond Energies of Ionic Compounds Li–F = 1036 kJ/mol Li-Br = 807 kJ/mol Na-F= 923 kJ/mol Na-Br = 747 kJ/mol Given the general trend with bond energi...

I did my best, can someone check and help me? 2.Based on the differences in electronegativities, with which atom is francium (Fr) most likely to form an ionic bond?(1 point) Fr–Cl = 2.46 Fr–At = 1.50 Fr–I = 1.96 Fr–Se = 1.76 *** 2.Based on the differences...

7. Endothermic reactions absorb a lot of energy. Exothermic reactions give off a lot of energy. Which type of reaction has a higher activation energy? Which one takes more energy to break up the bonds of the reactants?(1 point) Endothermic reactions have...

9. Cobalt ions form complex ions with water and chloride as shown in the reaction. The left side of the reaction is pink, and the right side of the reaction is blue. Co(H2O)62+ + 4Cl– + heat ⇄ CoCl42–+ 6H2O Which statement about the system at equilibrium...

13. How many atoms of oxygen will be found in the product(s) of the reaction? Fe2O3 + 3H2SO4 3 12 4 15**** 14. Use the table and equation to answer the question. Element Atomic Mass (amu) hydrogen 1 carbon 12 oxygen 16 CH4 + 2 O2 → CO2 + 2 H2O The law of...

Last questions I'll ask, I got the rest the rest :) And a quick thank you to Bob, you've helped me out a lot and even taught me some stuff I couldn't learn from school. You're amazing. 17 Which statement about the number of protons and neutrons in a nucle...

THANK YOU! I'll follow what you said and post 2 questions every 10 minutes so I don't overwhelm anyone. And I'm so sorry, I got desperate because I don't want to fail chemistry. I need to get to the next grade.

forgot to add this too (changed my answer) 3. Which statement is the best description of the energy found in molecules of water? (1 point) Hotter molecules have more kinetic energy.*** A molecule's temperature is not connected to its energy. Colder molecu...

Wow I actually understood this better than my text books. Thank you.

Wait so based off what you said this mean the answer is "Exothermic reactions have a higher activation energy. Endothermic reactions require more energy to break up the bonds of the reactants."?

Hold on I'm confused, give me a moment to think...

okay never mind, I stick with my previous statement.
