If 0.334 g of water was obtained from the equation N*M H2O ?N + M H2O, how many grams of the hydrate were heated
The Henry's Law constant for carbon dioxide gas in water at 25 oC is 0.031 mol/L-atm. Calculate the solubility of carbon dioxide in water at 25 oC in moles/L if the partial pressure of carbon dioxide in the headspace above a water sample is 1.68 a..
Draw a potential energy diagram to illustrate this reaction mechanism, assuming that the overall reaction is endothermic. Label reaction intermediates with "RI", and activated complexes with "AC"
write the chem equation for the reaction which occurs when solutions of potassium sulfide and iron (II) chloride are mixed.
1) How many moles of oxygen atoms are present in a sample that contains 3.86 moles of dioxygen difluoride O2F2? The answer I got from this was: 7.72 moles of O2 atoms?
Provide me with your exact logic used to get the answer. A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
Trouble understanding the relationship between the Ka and how acidic a chemical is. Is it safe to say that the more acidic a chemical is the higher the Ka value will be
How much energy would be required to melt 48 g of HCl at its melting point of -110.8C? Hfus for HCl is 14.2 cal/g and Hvap for HCl is 98.7 cal/g.
What is the purpose of dissolving the acetanilide in glacial acetic acid prior to beginning the nitration reaction? What happens when you mix sulfuric acid with nitric acid?
Describe the effect of this on [CH3COOH] and [CH3COO-] (their concentrations). Account for your answer in terms of number of moles of protons transferred. Also, has the capacity of the buffer been exceeded? Explain.
The reaction will be spontaneous at high temperatures because increasing the temperature of a system with a negative change in S eventually results in a positive change in G.
A carnot cycle engine is operated between a high temperature of 500K and at a low of 3000K. The work done is 800J. how much heat
The activation energy for the reaction O + O3 ? 2O2 is 25 kJ/mol, and the enthalpy change is ?H = -388 kJ/mol. What is the activation energy for the decomposition of O2 by the reverse reaction
