Write a balanced equation for the reaction between copper metal and nitric acid to produce copper II nitrate, nitrogen dioxide,
almond37 [142]

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:

4HNO_3(l)+Cu(s)----- > Cu(NO_3)_2(aq)+2NO_2+2H_2O

Thus, the above mentioned is the balanced reaction for the given scenario.

Veronica is taking an average of 16 height measurements in a brand-new experiment. Which term is this the best example of? repli
Karolina [17]

Answer:

repetition

Explanation:

Taking an average of 16 height measurements is an example of repetition. Repetition involves making and taking repeated measurements in an experiment.

The goal is to achieve a highly accurate and precise data from the experiment.

  • Replication involves duplicating another experiment and testing to see how valid they are.
  • Since Veronica's experiment is a brand new one, it's hypothesis has not been tested or replicated in any way.
  • Therefore, it is not a replication.
  • But she is repeating the experiment to obtain different values.
