it would obviously have no electrons or protrons
can a neutron exist without protrons and electrons?
would it have any use?

I need to find the percent yield (actual/theoretical x 100) of copper in an experiment:

i got 7.95 grams of copper sulfate in the beginning
copper was separated from the copper sulfate at the end and had a mass of 2.66

so how would i find the theoretical data? like how would i know how much of the copper sulfate was supposed to be copper?

i need to find the percent yield of copper. if you are good at chemistry, PLEASE HELP

I really need an actual number instead of a formula. Does anyone know it, or a link to it?

At my work, making coffees, several employees use steam to compress milk containers for the trash. Heres what they exactly do: They take the steam wand, insert it into the gallon jug hole, push in steam until the it reaches 150degrees. The result is a very hot milk container. Then they compress it. The gas that is pushed out is rather unpleasant smelling. Obviously there is some reaction between the heat or water vapor and the plastic jug.

Is this a health hazard? I looked up benzene then styrene and noticed styrene is a suspected carcinogen.

How would you know based on the information?

Also, Sulfur-48 has 48 protons and 16 electrons. How would you calculate the number of neutrons based on that?

Any help would be much appreciated.
