STOICHIOMETRY:

1. Solutions of ammonium chloride and potassium hydroxide are mixed. Ammonia, potassium chloride, and water are produced. You have 1.46g of ammonium chloride in solution and 1.08g of potassium hydroxide in solution. If the experiment yields 0.406g of water, what is the percent yield?

(I don't how to start, help!)

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
