I would have to say the best answer would be two
Answer:
Power plants that produce electricity emit at least two-thirds of all sulfur dioxide and more than one-third of all nitrogen oxides that pollute the air.
Hope this helps :)
Quantum states of electrons are usually written in terms of four numbers: the principle quantum number (n), the angular momentum azimuthal number (L), the magnetic quantum number (ml), and the spin projection number (ms). The quantum number set (4,1,0,+1/2) and (4,1,1,+1/2) share the same principle quantum numbers and therefore both sit in the n=4 electron shell.
Answer:
10.04 g of NaOH is required for neutralization
Explanation:
neutralization reaction:
Molar mass of NaOH = 40 g/mol
Molar mass of HCl = 36.5 g/mol
So, 9.16 g of HCl = moles of HCl = 0.251 moles of HCl
According to neutralization reaction, 1 mol of NaOH is required to neutralize 1 mol of HCl
So, 0.251 moles of NaOH are required to neutralize 0.251 moles of HCl
So mass of NaOH required for neutralization = () g = 10.04 g
The first part of the answer is in the photo attached. I hope i can attach a second photo...
