N2 + 3H2 ==> 2NH3 2.5 mols N2 x (2 mol NH3/1 mol N2) = 2.5 x 2/1 = ?
AP Chemistry Help!!
I worked this elsewhere for you.
How many mL HCl is needed? That's 50 x 0.2/0.4 = 25.00 mL Total volume = 75.00 mL Total mols = 0.050 x 0.2 =0.01 (salt at equivalence point) = 0.01/0.075L = approximately 0.13 If we call methylamine just BNH2 then the salt will be BNH3^+ and it will hydrolyze as follows: ....
Note the correct spelling of phosphorus. P4 + 5O2 ==> P4O10 The "answers" in your post make me think you are using phosphorus as P when in fact it is P4. Therefore, 8 mols P4 x (1 mol P4O10/1 mol P4) = 8 mols P4O10
There is no H2O added. Water is FORMED by the reaction.
1 mol CH4 gives you 1 mol C + 4 mol H; that's 6.023E23 atoms of C + 4*6.02E23 atoms H. Electrons in C atoms = 6.02E23*6e each = ? Electrons in H atoms 6.02E23*4atoms x 1e/atom = ? Add electrons in C and H together.
chem plz help :(
(P1V1/T1) = (P2V2/T2)
12.45g x (24L/1L) = ?g and convert to kg.
mols glutamic acid = 9.9/183.59 = estimated 0.05. mols KOH needed = estimated 0.05 MKOH = mols KOH/L KOH or L KOH = mols KOH/M KOH = estimated 0.05/0.96 = estimated 0.056 L or about 56 mL and that is one of the pKa values. Multiply that by 3 for total volume KOH required.
