Among the transition metal elements, Manganese and Zinc have a slight lowering of electronegativities. The reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. Both Manganese and Zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. Although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. Hence, the electronegativity (or the ability to attract electrons) is lessened.
Here we have to choose the partial pressure exerted by the air in the given sample among the given options.
The partial pressure of the air in the sample is C. 96.82 kPa.
As per the Dalton's law of partial pressure the total pressure of the gas in the pool (P) is equivalent to the summation of the partial pressure of water vapor and air pressure.
Mathematically we may write:
Now the 
Or, P_{Air}[/tex] = (100.18 - 3.36) kilopascals
Or, P_{Air}[/tex] = 96.82 Kilopascals.
Thus the partial pressure of the air in the sample is C. 96.82 kPa.
I disagree. Carbon is not a group 18 element. This is incorrect because elements closer to the top of the group are less reactive than those at the bottom of the group. Group 18 elements are noble gases and carbon, a group 14 element, is a non metal.
Answer: 2:2 but if simplified it’s 1:1
Explanation:
To find the molecular formula of the compound, we get the molar mass of empirical formula CH2o which is 30 g/mol. We divided the molecular mass of 90.087 g/mol by 30, we get 3. Hence, we multiply each element by 3, getting the molecular formula of C3H6O3.
