what about HCN, HCLO4, H2SO4 , are they strong acids or weak

what is a strong acid

determine the quantity of NaOh whose percentage is 15 % to balance 176 g of H2SO4

need to calculate the mass (m ) of NaoH with C% = 15 % , to balance 176 g of H2SO4 so i though to use this method C% = mass of h2s04 / mass of h2so4 + mass of Naoh which is unknown mass of Naoh = c% x mass of h2so4 / 100 is this the right method or not ?

ok this problem has made me crazy , 15 % is w\v ok , so i just the m1 , the mass of naoh i don't need the volume , so ill reformulate the problem again , I need the mass of naoh with conc.15% w/v in 176 g h2so4 ok

the problem requires the quantity of NaOH, this is what i don't understand what does it mean by quantity , the volume , the mass ,or the molar concentration ?? I have to use all the things that are give to the exerc. including the 15 % concentration of Na...

determine the quantity of NaOH whose concentration is 15% to neutralize 176g H2SO4 , this is the exact problem and no its not an experiment.

determine the quantity of NaOH whose concentration is 15% w/v to neutralize 176g H2SO4 , this is the exact problem and no its not an experiment. sorry to bother someone of you

how to know if an acid is weak or strong , i simply don't understand the idea of dissolving or not dissolving completely in water ,,,,

can u mention me 5 acidic salts , 5 basic salts and 5 neutral salts ?

can someone give me 5 examples for the conservation of the angular momentum , 5 for the conservation of the impulse , and 5 for the conservation of the mechanical energy , in sport , arts or in technique , or just give me a site to find these examples, bu...

balance: Cr(OH)3+Na2O2---- Na2CrO4+H2O+NaOH

H2SO3 SORRY

15 % w/v

thanks a lot

no i really need 5 of each category i mentioned above

not for all of them **
