The lab question is “based on a substance’s properties, how can you determine whether its bonds are ionic or covalent? ” fill in the box to answer this question with a hypothesis.
hypothesis: if a substance contains ionic bonds, then its properties would include . .

the answer is a and have a great day

it's c (engineer's do their work with mechanical stuff not on any living being)

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.  

the correct answer would be b) volume versus temperature, because they are also directly proportional.
