How many mol of proton are needed to change the pH of 0.200M Arg solution, 100 ml, from an initial pH of 12.2 to a final pH where the net charge of arginine is +1.80? (Assume addition of proton doesn’t dramatically affect the final volume of solution)
Answer the following questions if the value of the principal quantum number is 4 (n=4 or shell = 4). The number of subshells (in this shell) is 4 subshells. The number of orbitals possible in this shell is 32 orbitals. The maximum number of electrons possible in this shell is 32 electrons. The highest energy orbitals in this shell, use the letter F the orbitals. to indicate the shape of Next Question 3 4 pts Combustion of 28 g NH3 produces 25 g of NO. Calculate the percent yield.
