The answer is (1).
Quantum mechanics views electron orbitals not as fixed circular paths or defined boundaries, but as probablility distributions that represent the probability of finding an electron at any point in space around the nucleus. For simplicity, discrete "boundaries" are often drawn enclosing the area where electrons should be found 90% of the time.
Answer:
The answer to your question is: Flask X
Explanation:
Data
Flask X Flask B
Molar mass 30 g 60 g
mass 1.2g 1.2 g
Pressure 1 atm 0.5 atm
Formula PV = nRT
In the formula, we can notice that the number of moles (n)
is directly proportional to the pressure.
Then, let's calculate the number of moles
flask X flask Y
30 g --------------- 1 mol 60 g -------------- 1 mol
1.2 g ---------------- x 1.2 g ------------- x
x = (1.2 x 1) / 30 x = (1.2 x 1) / 60
x = 0.04 mol x = 0.02 mol
From the results, we conclude that the flask with the gas of molar mass 30g is the flask with pressure of 1 atm, because the higher the number of moles, the higher the pressure.
3, 9, 16 are correct! 17 should be b because buffered means that it resists change in pH
An ionic bond will most likely form
covalent bonds form when an electron is shared and ionic bonds form when an electron is transferred
