If anyone can prepare a 1 M solution of Mg(OH)2, I would like to see it. The solubility of of magnesium hydroxide in water is 12 mg/L. The Ksp is 4.5x10^-11.
I assume the desired pH is 8.65 although you did not label it, as DrBob pointed out. Ka = [H+][NO2-] / [HNO2] [H+] = antilog(-8.65)=2.24x10^-9 (a basic solution) [OH-] = Kw / [H+] [OH-] = (1x10^-14)/(2.24x10^-9) = 4.47x10^(-6) Ka = [H+][NO2-] / [HNO2] = 4.5x10^-4 (looked up) K...
We need the chemical equation for the reaction between CH4 and O2. I assume it was: 2CH4 + 3O2 -->2CO + 4H2O To answer your question, 1. Divide 45.6g by the molar mass of CH4 to get the number of moles of CH4. 2. Divide 73.2g O2 by the molar mass of O2 to get the moles of ...
The mass of 1 liter of water is very close to 1 kg q = (specific heat)*(mass)*deltaT specific heat of water = 4.18kJ/kg.C q = (4.18kJ/kg.C)(1.00kg)(85ºC-18ºC)
Salicylic acid which was probably used to make aspirin is a phenol. The negative phenol test indicates that all of the salicylic acid reacted. However, the aspirin produced was not pure. Impurities lower the melting point and make the melting point range wider. It would be har...
The deltaH for the decomposition of 1 mole of Al2O3 is half of 351.4 kJ since the chemical equation shows 2 moles of Al2O3. Convert 12.50g Al2O3 to moles by dividing it by the molar mass of Al2O3. Multiply your answer by 351.4kJ to get the enthalpy of decomposition of 12.50g A...
CH3CH2CH2CH2OH + NaBr --> CH3CH2CH2CH2Br + NaOH. NaOH would react with H2SO4 to form Na2SO4 which may precipitate in a mixture of organic solvents.
Para (p-), meta (m-), and ortho (o-) are only used for derivatives of benzene. Your acid was probably 4-methylcyclohexanoic acid.
Start with: CH3CH2CH2-C-OCH(CH3)2 To the middle -C-, attach an -OH (up) and an -H (down). See also: http://en.wikipedia.org/wiki/Hemiacetal
