Ionic Bonds - A bond between metal and nonmetal elements. Involves transferring electrons. Covalent Bonds - Also known as molecular bonds. A bond between two nonmetals.
The activated complex is the intermediate that is formed between the states of reactants "F" and products "G".
Letter A represents the activation energy of the reaction, that is the difference in potential energy between the reactants "F" and activated complex "B".
Letter C represents the enthalpy change of the reaction, that is the difference in potential energy between products "G" and reactants "F".
Letter D represents the potential energy of products "G".
Letter E represents the potential energy of reactants "E".
I belive it's the black chair because they were asking which chair experienced the most force in the begining and the black chair had the most force given.
The molecular weight of K2SO4 is 174.26 g/mole. The mass of K2SO4 required to make this solution is calculated in the following way. 550mL * (0.76mole/1000mL) * (174.26g/mole) = 72.84gram <span>I hope this helps.</span>
