When uranium<span> comes in contact with oxygen in the air, it rusts, just like iron does, but </span>uranium<span> rust is black and not red. Like other heavy </span>atoms <span>such as iron, </span>uranium atoms<span> have more neutrons than they do protons. Not all </span>uranium atoms<span> have the </span>same<span> number of neutrons.</span>
The answer is A i think from the options though the answers are worded a bit weird
It has different moleculs sorry I am guessing
This problem is providing us with the mass equivalent to one troy ounce. Thus, the troy ounces of gold in one short ton of average Nevada ore is required and found to be the 0.103 otz according to the following dimensional analysis.
<h3>Dimensional analysis</h3>
In chemistry, a raft of problems do not always provide an equation in order to be solved yet dimensional analysis can be applied, so as to obtain the desired amount in the required units.
Thus, since this problem asks for try ounces in an average Nevada ore, which has 3.2 grams of gold per short ton of ore, one can solve the following setup in order to obtain the required answer in otz:

Where the short tons are cancelled out as well as the grams, in order to obtain:
