H2SO4 + 2RbOH -> Rb2SO4 + 2H2O
If you want an explanation, keep reading.
In the first portion, there are two hydrogen ions and four sulfate ions.
The second portion has one rubidium ions and one hydroxide ion.
On the other side of the equation, in order to keep those two rubidiums balanced, you'll need to add a two at the beginning of the second portion, but in that process you are giving a second hydroxide value.
Back to the right side, there is there is water (H2O).
On the first portion, there were two hydrogen ions. The second portion also has two hydroxides because of the value change (adding the two to the front).
So on the fourth portion, you'd have to add another two so you could balance the four hydrogen ions (H2 and 2OH) and the two oxygen ions (2OH).
I hope this was easy to understand.
Answer:
Symbol is Sn
Explanation:
From the periodic table, the element that has an ionic number of 50 and electronic structure of 1s² 2s² 2p^(6) 3s² 3p^(6) 3d^(10) 4s² 4p^(6) 4d^(10) 5s² is known to be Tin.
The symbol for Tin is written as Sn
<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.
