Nitric acid basically reacts with copper as per to the reaction given 4 HNO3(l) + Cu(s) -----> Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O(l).
<h3>What is a balanced reaction?</h3>
A balanced reaction includes the same number of elements on both sides of the equation.
In a chemical reaction, the stoichiometric coefficient is the number written in front of atoms, ions, and molecules to balance the number of each element between the reactant and product sides of the equation.
The balanced reaction for reaction between copper metal and nitric acid to produce copper II nitrate, nitrogen dioxide, and water will be as follows:
Thus, the above mentioned is the balanced reaction for the given scenario.

Answer:
Dna is a molecule. It carries hereditary information. It is located in the chromosomes.
You multiply the molarity by the volume in litres.
Explanation:
Molarity is the number of moles of a substance in one litre of solution. The official symbol for molarity is “c” (concentration), but many people use the old symbol “M”.
M
=
n
V
, where
n
is the number of moles and
V
is the volume in litres.
We can rearrange this equation to get the number of moles:
n
=
M
×
V

:
How many moles of
NaCl
are contained in 0.300 L of 0.400 mol/L
NaCl
solution?
Solution:

0.120 mol NaCl
Answer:
Explanation:
When filling a burette for a titrant, adjust the burette so that the opening is near or below the eye leve preferably over the sink.
Then, use a funnel to add the titrant into the burette.
The titrant should be filled almost to the zero mark.
