Maybe to not get rained on.
Hahhahahaha I ain't sure tho
Explanation:
i found this the question is different but I think the situation is same
since both the jars are kept at the same temperature the vapor pressure will be same in both the cases.
The total number of elements that one particular element can bond to can be determined by simply drawing the Lewis structure of the element.
Place the chemical symbol
Then look at the group number = valence electrons
Distribute the valence electrons around the atom.
C = 4 bonds
N = 3 bonds
O = 2 bonds
