What do these two changes have in common? newly poured concrete becoming hard a log decomposing in the woods Select all that apply. Both result in a different type of molecule than was there before. Both are only physical changes. Both involve chemical bonds breaking. Both are changes of state.

The newly poured concrete becoming hard is a chemical change, because the water contained in the concrete causes the concrete to harden through a Chemical process known as hydration. while

The decomposing log in the woods is also a chemical process because the chemical properties of the log before decomposition will be altered due to the breaking of chemical bonds which occurs during decomposition of substances.

Both process will also lead to change in state and result in different type of molecule from the original form.

Hence we can conclude that These two changes have ; ( A, C and D ) in common
