Answer:
the last answer, and I'm stuck on this one too
Explanation:
I did the test
Answer:
163.94
Explanation:
Na = 22.99 (3)
P = 30.97
O = 16.00 (4)
22.99(3) + 30.97 +16.00(4) = 163.94
Hope that helps
Answer:
D (But as a heads up, you wrote barium instead of Bromine)
Explanation:
The Potassium atom will lose an electron since its valence shell only has one, while Bromine has 7 electrons in its valence shell. Potassium wants to get rid of its one electron, Bromine wants to gain that one electron to get a full shell.
Potassium will become a CATION with a positive charge (since it lost an electron), Bromine will become an ANION with a negative charge (since it gained an electron)
<u>Answer:</u>
<u>For a:</u> The reaction is a type of synthesis reaction.
<u>For b:</u> The reaction is a type of double displacement reaction
<u>For c:</u> The reaction is a type of combustion reaction.
<u>Explanation:</u>
The given chemical reaction is:
The above reaction is a type of synthesis reaction because calcium and bromine are combining in their elemental state to form a calcium bromide compound.
The given chemical reaction is:
The above reaction is a type of double displacement reaction because here exchange of ions takes place.
The given chemical reaction is:
The above reaction is a type of combustion reaction because a hydrocarbon is reacting with oxygen gas to produce carbon dioxide and water molecule.
