I believe its C because 7.5 would be considered a base and when acid it’s added it’s PH neutralizes the solution
Answer:
wdescribes the probability of finding an electron in space.
Explanation:
The quantum mechanical model of the atom assigns wave properties to the electron. This is in accordance with Heisenberg's uncertainty principle.
The probability of finding the electron in a given volume element is given as the square of the wave function while the wave function itself does not really have a physically significant meaning.
However, the wave function is a mathematical function that contains a detailed information about the behavior of an electron.
1 mole of NaHCO3 = 84g
1 mole of NaHCO3--------------84g
x moles of NaHCO3----------0,50g
x = 0,00595 moles of NaHCO3
0,00595 moles of NaHCO3----------in--------250ml
x moles of NaHCO3-------------------in-----------1000ml
x = 0,0238 moles of NaHCO3
answer: the molar <span>concentration of NaHCO3 is 0,0238mol/l</span>
