Explanation:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs
The general formula for a decomposition reaction is shown as option C. AB -> A + B. This type of reaction is simply when a complex compound and or substance is broken down to form its substituent atoms of their respective elements. It is energy releasing as compounds are broken down and is the inverse of a synthesis type of chemical reaction.
Answer:
Transition metals, alkali metals, alkaline earth metals Transition metals - Middle of the periodic chart, only average reactivity. alkali metals - As mentioned above, very reactive. Bad choice, going from lower reactivity to higher reactivity.
