2. Precipitation, because when it rains the water that was taken when it was evaporated is replaced and it fills the lake back up
Answer:
194 g/mol.
Explanation:
Hello,
In this case, one first must compute the mass of each element as shown below:

Next, the corresponding moles:

Then, each element's subscripts is found to be:

Therefore, the empirical formula is:

Nonetheless, it has a molar mass of 97bg/mol, thereby, by multiplying such formula by 2 one gets:

Which has a molar mass of 194 g/mol being correctly contained in the given interval.
Best regards.
Volume = Mass / Density
Volume = 540g / 2.70 g/ml
Volume = 200 ml
The properties of the atomic orbital are actually
dependent on the quantum numbers.
size of atomic orbital: governed by the principal quantum
number (n)
shape of atomic orbital: governed by the angular momentum
quantum number (l)
orientation in space: governed by the magnetic quantum
number (ml)
Since we are asked about the shape, hence the correct answer
is:
angular momentum quantum number (l)
