But Dr.Bob,from what I refer,NH3+CH2COOH is the strongest acid since it has both acid and NH3 protonated.Acetic acid is a weak acid,I'm not sure about the CH3CONHCH2COOH. That's what confuses me
Chemistry
Arrange these acids in terms of increasing acidity: CH3COOH, NH3+CH2COOH, CH3CONHCH2COOH My answer is CH3COOH,CH3CONHCH2COOH,NH3+CH2COOH . Is this correct Dr.Bob?

How many stereoisomers are possible for threonine?
Chemistry
Ok thank you Dr.Bob
Chemistry
How many stereoisomers are there for 1,2-dichlorocyclopentane? The answer options are 1,2,3 & 4. I think it is 4 because there is one cis & one trans isomer,so when using the 2^n formula,the final answer is 2^2 =4.Is my approach correct? Need ur help Dr.Bob.Thanks
Chemistry
For a system where: NH2OH + CH3NH3+ --> CH3NH2 + NH3OH+ 95% 95% 5% 5% State of equilibrium in the system is described by the percentages given above.Which of the species above is the strongest acid in the system? My answer is CH3NH3+, is it correct?
Chemistry
500.0 mL of 0.220 mol/L HCl(aq) was added to a high quality insulated calorimeter containing 500.0mL of 0.200 mol/L NaOH(aq).Both solutions had a density of 1g/mL & a specific heat of 4.184 J/g.K.The calorimeter had a heat capacity of 850 J/C.Temperature of entire system rose ...
Chemistry
Sorry what I meant was dividing the total heat with mole of NaOH ,not mass.
Chemistry
Ok,then how do I find the dH of NaOH? Do I need to use the total heat of the system and divide it by the mass of NaOH to get its dH ? I'm still confused Thank you
