Answer:
Explanation:
Hello.
In this case, given the volume (1cm³=1mL) and density of the bromine we are to firstly compute the mass since it will allow us to compute the representative particles:
Next, since the mass of one mole of diatomic bromine is 159.82 g (one bromine weights 78.91), we can next compute the moles in that sample:
Finally, via the Avogadro's number we can compute the representative particles of bromine as follows:
Best regards.
Answer:
There are some like Argon, Helium, and Krypton.
Explanation:
Basically any noble gases hope this helps :3
1. element
2. compound
3. element
4. compound
5. compound
6. compound
basically, if its on the periodic table, its an element. for example, rock can be made of many things in the periodic table, therefore its a compound. salt, is NaCl, which are two elements put together, therefore its a compound.
Answer:
just do it
