The answer is A. Because when stirring butter and sugar together it makes a odor and odor always involves a chemical change.
The greater the number of electrons an atom has to borrow or to lend, the greater the activity of the atom.
Answer:
B. Keq = [SO₃][NO]/[SO₂][NO₂].
Explanation:
- For any equilibrium reaction:
Keq = [products]/[reactants].
- For the reaction: SO₂(g) + NO₂(g) → SO₃(g) + NO(g).
<em>∴ Keq = [SO₃][NO]/[SO₂][NO₂].</em>
