Hg + O2 --> HgO + O
Note that Mercury has a variable valency.
Answer: New concentration of is 0.23 M.
Explanation:
The given data is as follows.
Moles of = 0.06 mol
Moles of = 0.08 mol
Therefore, moles of added are as follows.
Moles of =
= 0.003125 mol
Now, new moles of = 0.06 + 0.003125
= 0.063125
Therefore, new concentration of will be calculated as follows.
Concentration =
= 0.23 M
Thus, we can conclude that new concentration of is 0.23 M.
The type of change is chemical change. This reaction yields compounds with different identities that is carbon dioxide,Calcium chloride and water
Answer:
I'm not sure sorry
Explanation:
all I know is calcium=1 carbon=1 oxygen=3➡️calcuim=1 oxygen=1+carbon=1 oxygen=2
so overall answer would be (5➡️2+3) so mabey 5+5=10
Bohr's model of the atom states that electrons orbit an atom's nucleus in electron shells of increasing energy. The electrons are free of physical contact with the nucleus, but are held in orbit due to the electrons' attraction to the oppositely charged protons in the nucleus.
Thomson's model, or the plum pudding model, it describes atoms as spheres of positively charged matter, in which electrons are embedded in.
The key difference is the locations of, and the motions of the electrons.
