Explanation:
Hello,
In this case, since the first step is to write the properly balanced chemical reaction:
We can see that given the 0.200 g of P4S3 (molar mass 220 g/mol) the mole ratio between it and SO2 (molar mass 64 g/mol) is 1:3, therefore, the produced mass of SO2 turns out:
Best regards.
Answer:
The option D is correct answer.
If the outer shell is filled, the atom is stable. Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability. Example of an unstable atom with a single electron in its outer-most shell. ... In covalent bonds, atoms share electrons to achieve stability.
Hope this helped!
The copper has a normal atomic mass of 63.546
it's atomic number is 29
it's atomic mass is 63 disregarding other mass in atom
Atomic mass - atomic number = neutron mass
63 - 29 = 34
Hope this helps
Answer:
1st column group 1 - group2
second column Halogen group - zero group ( inert gases )
third column - very active metals , tend to lose one electron -less reactive than group one , tend to lose 2 electrons - very active nonmetals, tend to gain one electron - Nobel gases , do not gain or lose electrons
