Calculate deltaH degrees for each of the following reactions: 4Na(s)+O29g) 2NaO(s) 2Na(s)+2H2O(l) 2NaOH(aq)+ H2(g)
When an aqueous solution of sodium sulfite is added to an aqueous solution of hydrobromic acid, a gas evolves. Write the balanced chemical equation
Given the quantities of chemicals used in this recipe one could believably have gotten a 100% chemical yield without having completely reacted all of the magnesium, or without having completely reacted all of the bromobenzene
As the reaction proceeds, the specific rotation eventually drops to zero. Further analysis shows that the specific rotation falls to zero after half of the radioactive iodine has been consumed. Explain this observation
The reaction below reaches equilibrium in a closed reaction vessel. The enthalpy change for the forward reaction is +135 kJ/mol. Does the mass of Na 2 CO 3 increase, decrease or stay the same if the mixture is transferred to a smaller reaction ves..
