The reaction between two deuterium atoms (2H) produces a 3H atom and a neutron (1n). The mass of the reactants is 4.0370 atomic mass units (amu) and the mass of the products is 4.0237 amu. The difference in mass is 0.0133 amu. How can you account for this mass difference?

The "missing" mass is due to inaccurate measurement on a very small scale.

        
The "missing" mass has been converted to energy.

        
The "missing" matter has been converted to mass.

        
The "missing" mass has been converted to matter.

I believe the missing mass was converted to energy..

If you notice, the mass of the reactants > mass of the products. After the conversion, the mass is decreased. That decrease suggests that the mass had to go somewhere because if it had converted to mass, the mass would actually be equal, or more than the mass of the reactants. It is not inaccurate because the the question gives you all the data, which should be accurate. The question basically calculates everything for you. I would still double check your book about the topic on the reaction of deuterium atoms just in case.

I will, thank you soooo much! Chemistry is killing me lol.. I don't know if you could possibly help me with around 3 more questions? I can post them in the question area so I can give you medals because honestly you sound brilliant compared to what my brain is able to absorb...

I would like you to take a look at this @ http://is.gd/hIBBCt On this site page, it explains that 2H is known as Deuterium and 3H is known as Tritium. Additional reading may help you find a better answer than what I provided if applicable. That was why I suggest you checking again to make sure my information is correct.
