A thermometer because it is the only tool that measures temperature.
Food that contains nuts should be prepared last
Answer:-
H+ + OH- --> H2O
Explanation:-
The chemical equation is NaOH + HNO3 --> NaNO3 + H2O
Now for the ionic compounds
HNO3 --> H+ + NO3 -
NaOH--> Na+ + OH-
NaNO3 --> Na+ + NO3-
Water being covalent will remain as H2O,
Hence
HNO3 + NaOH--> NaNO3 + H2O
H+ + NO3 - + Na+ + OH- --> Na+ + No3 - + H2O.
Crossing out common terms
H+ + OH- --> H2O
The equilibrium shifts to the right to favor the formation of the products. Le Chatelier's principle states that a system will do what it takes to negate any changes made or added to it.
The answer is the upper right Fluorine is the most electronegative.
