What will happen if we combine the solution of sodium iodide and the solution of lead(ii) nitrate?
a. the solutions will mix, so all of the ions will be evenly distributed throughout the entire solution.
b. but sometimes mixing solutions containing dissolved ions leads to a precipitation reaction: the formation of a new insoluble compound.

option B. But sometimes mixing solutions containing dissolved ions leads to a precipitation reaction: the formation of a new insoluble compound.

Explanation:

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.  

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
