F. because electronegativity generally increases as you move from left to right across a periodic table, and F is farther right than O
“Metal ions are typically smaller than their corresponding neutral atoms”
Answer) Smaller
1) The answer is: 2 moles of oxygen molecules.
Balanced chemical reaction of methane combustion:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g).
Coefficients with the lowest ratio indicate the relative amounts of substances in a reaction.
In fronf of oxygen molecule is coefficient 2.
2) The answer is: 4 moles of oxygen atoms.
In one molecule of oxygen there are two oxygen atoms, so in two molecules there are four oxygen atoms.
I am pretty sure nitrogen would be the solvent because solvents are generally the larger amount
