CHEM QUESTION

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?

A. The "missing" mass is due to inaccurate measurement on a very small scale.

B. The "missing" mass has been converted to energy.

C. The "missing" matter has been converted to mass.

D. The "missing" mass has been converted to matter.

Answer 1

Answer:

B. $\displaystyle The\:"missing"\:mass\:has\:been\:converted\:to\:energy.$

Explanation:

If you have not notised, the mass is the products are less than the mass of the reactants. The mass is reduced after the conversion. This decrease indicates that the mass had to be somewhere because the mass would probably have been equal, or greater than the mass of the reactants if it had been mass. This is accurate because all the data that should be correct are provided by the query. Essentially, the question decides all for you.
