When the ions co2− 3 , cl−, no− 3 , na+, nh+ 4 , fe2+ are mixed in aqueous solution, what substance is likely to form an insoluble precipitate?

The substance likely to form an insoluble precipitate is

Explanation:

The test for cation when is mixed in aqueous solution such as NaOH (sodium hydroxide) produces an insoluble precipitate

the answer is a and have a great day

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.
