Assuming gasoline is 100% isooctane, with a density of 0.692g/mL, what mass of carbon dioxide is produced by the combustion of 1.2x10^10 gal of gasoline (the approximate annual consumption of gasoline in the U.S.)?
10th grade Chemistry
Sorry I meant Na2CrO4 and Na2Cr2O7 and basically i need to know if they react exactly the same with different elements
10th grade Chemistry
Will Na2CrO4 react exactly the same as Na2CrO7 when mixed with Pb(NO3)2
Chemistry
Will Zinc react with Zn(NO3)2, Cu(NO3)2,Pb(NO3)2, Mg(NO3)2, AgNO3, Al(NO3)3, or Fe(NO3)3
