How do the properties of a compound compare to the properties of the elements that make it up? a. the properties of the compound are the same as the properties of the elements that make it up b. the properties of the compound may vary, while the properties of the elements that make it up do not change c. the properties of the compound are different from the properties of the elements that make it up d. the properties of the compound are the same as the properties of only one of the elements in the compound

A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
