Answer:
Na2O+H2O=2NaOH
Step by step exp.
Given:
Equation Na2O+H2O=NaOH
To find: Balance the equation
Solution:
Taking LHS of the equation
LHS=Na2O+H2O
There is 2 sodium, 2 oxygen,& 2 hydrogen
To balance the equation we have equal number of atom so we multply 2 to the RHS=2NaOH
There fore the equation form is
Na2O+H2O=2NaOH
<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.
Answer:
Because it only needs one more electron to get to a full valence shell (8), so it really wants it and is pulling other electrons in. It also has to do with needing one more electron to fill the 2p shell. It is a small element which means its electrons are pulled tightly to the nucleus.
Hope this helps!
Explanation:
Answer:
Explanation: potassium (Na) has one electron in outer shell
And it donates it easily and can even reduce
Hydrogen gas from water. An alkaline solution containing
Hydroxide ions (OH-) is then formed
