Which reaction would cause a decrease in entropy? A. 2CCI4(9) + O2(g) → 2C0Cl2(g) + 2Cl2(g)

B. CO(g) + 3H2(g) → CH4(9) + H2O(g)

C. 2NH3(g) → N2(g) + 3H2(g)

D. 2NOCI(g) → 2NO(g) + Cl2(g)

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.

Nonmetal are moldable and easily shaped

It would be true sodium reacts with water in a violent way
