Answer:
Oxygen atom, because the partial negative charge is localized on the oxygen atom.
Explanation:
A cation is a positive ion, so to associate with it, would be necessary a negative ion, an anion. When the water dissociates, it will form 
and 
.
So, oxygen has a negative charge, and in the molecule, the partial negative charge because it's more electronegative. Then, oxygen will be associated with the cation.
It says Methane+Oxygen forms Water+Carbon dioxide and everything is in gaseous state.

The molarity of a solution is 0.909 M.
m(CaCl₂) = 82 g; mass of calcium chloride
M(CaCl₂) = 111 g/mol; molar mass of calcium chloride
n(CaCl₂) = m(CaCl₂) ÷ M(CaCl₂)
n(CaCl₂) = 82 g ÷ 111 g/mol
n(CaCl₂) = 0.74 mol; amount of calcium chloride
V(CaCl₂) = 812 mL = 0.812 L; volume of calcium chloride
c(CaCl₂) = n(CaCl₂) ÷ V(CaCl₂)
c(CaCl₂) = 0.74 mol ÷ 0.812 L
c(CaCl₂) = 0.909 mol/L = 0.909 M; molarity of calcium chloride
Calcium chloride is a inorganic salt with ionic bonds between calcium and chlorine. It is a colorless crystalline solid at room temperature, highly soluble in water.
