A green plant has chemical energy
Chemical Property
<u>Explanation:</u>
When a substance is changed into another substance, may be due to addition of some other substance or removal of water from that substance.
* its identity changes
*its reactivity changes
*reactivity towards water, air and many other substances will change
*its chemical composition changes
and all these changes occurs due to the chemical properties.
If the physical property changes then there will be change in the state of matter, but its boiling point, melting point , reactivity towards water, air and other substances will not change, and it will not lose its identity.
Answer:
mole
Originally, a mole was the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro's Number, which is roughly 6.02x1023. A mole of carbon atoms is 6.02x1023 carbon atoms.
