Nuclear properties
Naturally occurring beryllium, save for slight contamination by the cosmogenic radioisotopes, is isotopically pure beryllium-9, which has a nuclear spin of 3/2.Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites.
Explanation:
hope this helps if not let me know
Answer:
its the 3rd option.
the molecules move from region of higher concentration to a region of lower concentration.
Explanation:
please do give me brainliest if this helped you.
thank you and have a great day :D
Answer:As you have asked, I will not do your homework for you but will outline the reasoning…
Find out the atomic weight of all the species involved in the problem. Three decimals is more than sufficient.
Look at the periodic table of the elements and other resources (notes!) as necessary to determine the expected valence of the species
Once you know how many of these go with those, you are cruising…
You already know that 4Al+3O2→2Al2O3
So, you are in a great position to determine the number of moles of O2 , as you know you have 14.8 mol of Al and the ratio of combination is always 4 molecules.
