Copper would be the last to melt because it has the highest melting point!
Positive applications for allelotoxin is that it prevents plants from enduring any type of competition with other species.
<h3>What is Allelopathy?</h3>
This is the process in which a plant inhibits the growth of another through a secretion of a chemical which is referred to as allelotoxin.
This technique however reduces biodiversity which isn't ideal so as to prevent organisms from going extinct and also reduces adaptation or evolution due to the reduced or non growth of the plant species which are affected.
A common example is the sorghum plant preventing of the growth of weeds thereby resulting in the most appropriate choices for the positive applications of allelotoxin.

Answer:
C. Chemical change
Explanation:
A physical change is where something is changed but it doesnt affect the build up of the chemical. For example, if you broke sticks and threw them on the ground, that would be a physical change because the change is happening to the physical being of the object and not its chemical buildup. However, if you lit those sticks on fire, that would be considered a chemical change because you end up with two substances, ash and the remnants of the stick. A nuclear reaction would result in something blowing up so its not that. And a physical property is like what it looks like or how it smells. Hope I helped you!
Answer:
C
Explanation:
This is a synthesis or a combination reaction , which involves the oxygen combining with sodium to make one compound.
