Answer:
B. A compound has different properties than the elements from which it is made
Explanation:
B is true because individual elements have different properties than the compound. Take NaCl (salt) for an example, Na (sodium) by itself is so reactive that if it touches water, it literally blows up (watch videos on the web very neat!), but when we pair it with Cl and make NaCl, it dissolves quietly and neatly, so we see that individuals elements have different properties than the final compound.
