You can do something like natural disasters and explain why they happen
Answer:
C. By being honest in recording the results of their own experiments
Explanation:
Honesty in recording results is ethical behaviour and the basis of scientific research.
A. is wrong. If you repeat the same experiment, you should always get the same result.
B. is wrong. Copying someone else's results is cheating and certainly unethical behaviour.
D. is wrong. Making up data is dishonest and unethical behaviour.
E. is wrong. Following your own instincts about safety procedures is unethical because your instincts may be wrong. following them may result in injury to yourself or to others.
Answer:
Sodium is an alkali metal, so it has an electronegativity that is far less than Chlorine. What this means is that Chlorine has a higher tendency to attract electrons from Sodium, which is what defines ionic bonds.
Explanation:
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.
