The fourth combination is not allowed.
The third quantum number, i.e. m subscript l, only may an integer number from -l to + l. Given that l = 0, the only allowed m subscript l is 0.
Ionic bond is formed due to the transfer of electrons from one atom to another so that all atoms involved in the bond would become stable (with 8 electrons in the outermost level)
Now, for bromine, it has 35 electrons. This means that bromine has 7 valence electrons in the outermost level. Therefore, bromine needs to gain one electron in order to become stable.
Bromine can react with elements from:
group 1: each element in group 1 needs to lose one electron to become stable. Therefore, one bromine atom can form an ionic bond when combined with an atom of an element from group 1 (element in group 1 loses its electron for bromine atom).
group 2: each element in group 2 needs to lose two electrons to become stable. Therefore, two bromine atoms can form ionic bonds when combined with an atom of an element from group 2 (element in group 2 loses two electrons, one for each bromine atom).
group 3: each element in group 3 needs to lose three electrons to become stable. Therefore, three bromine atoms can form ionic bonds when combined with an atom of an element from group 1 (element in group 3 loses three electrons, one for each bromine atom).
Since no choices are given , I cannot tell the exact choice. But the correct one would be the element from either group 1 , 2 or 3.
I believe ions (polyatomic or otherwise) would be neither polar nor nonpolar, but rather ionic. Polar and nonpolar are terms used to refer to molecules with an overall neutral charge, while ions are charged molecules or atoms. However, ions would BEHAVE LIKE polar molecules in the way that they are water soluble and lipid insoluble<span>

Answer:
Lactic acidosis occurs when there is greater than 1.60 g in 4445 mL of blood
Explanation:
A normal blood lactic acid level is 0.5-1 mmol/L.
Mild to moderately elevated level of blood lactic acid known as hyperlactatemia occur when the range is between 2-4 mmol/L without metabolic acidosis.
Lactic acidosis occurs with blood lactic acid levels of > 4 mmol/L
Molar mass Lactic acid, C₃H₆O₃ = 90 g/mol
Mass 4 mmol lactic acid = 0.004 mol * 90 g/mol = 0.36 g
Mass of lactic acid in 1 litre or 1000 mL of blood = 0.36 g
Mass of lactic acid in 4445 mL of blood = 0.36 g * (4445/1000)
<em>Mass of lactic acid in 4445 mL of blood = 1.60 g</em>
