In the analysis of 0.5 g sample of Feldspar , a mixture of chlorides of Na and K are obtained , which weighs 0.1180 g. subsequent treatment of mixed chlorides with AgNO3 gives 0.2451 g AgCl . what is % of Na2O and K20 in feldspar.
the reaction of dinitrogen pentoxide with ammonia to form water vapor and nitrogen is hypothetical in the gas phase
The lower flammability limit (LFL) for a gas is the minimum concentration of the gas, in air, below which there is too little fuel to support combustion.
After doing some analysis the probe finds out that the gas pocket contains an element that has an ionization energy of I=1453kJ/mol and an electron affinity of EA=51.0kJ/mol. Explain what is the identity of this element
Draw the structure of the potential product if an elimination reaction takes place instead of substitution. NaBr + H2SO4 ---> HBr + NaHSO
They hydrogen atom is not actually electronegative enough to form bonds to xenon. Were the xenon-hydrogen bond to exist, what would be the structure of XeH4
Assume you place 0.167 grams of a gaseous compound in a 0.346 Liters flask. It exerts a pressure of 0.427 atm of 30 degrees Celsius.
What is the Cro4^2- concentration in a solution that is 0.0375 M in chromic acid and 0.150 M HCl
Calculate the concentrations of the protoneated and unprotonated forms of bromothymol blue in 100 mL of a pH 8.1 buffer solution to which 1.0 mL of 0.005 M solution of bromothymol blue in 80% wate/20%ethanol has been added.
Calculate the pH of a solution containing 0.15 M acetic acid and 0.25 M sodium acetate. For acetic acid, Ka= 1.8 X 10-5. Either as a buffer system or use ICE table. NaOAc is strong electrolyte
