Answer:
Training officers in how to properly collect evidence
Explanation:
Forensic science is an interesting branch of science that involves the use of scientific procedures to solve a crime case. It encompasses collection of physical evidence from the crime scene and analyzing it in a laboratory using scientific means.
A forensic scientist is the individual in charge of performing these scientific procedures. His/her major role is to run the scientific analysis of the physical evidence brought in by the officers, however, he/she can also perform the task of training officers in how to properly collect evidence, in order not to damage the evidence or render it invalid for use.
Answer:
NaOH
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
2NBr3 + 3NaOH —> N2 + 3NaBr + 3HOBr
The limiting reactant can be obtained as follow:
From the balanced equation above,
2 moles of NBr3 reacted with 3 moles of NaOH.
Therefore, 40 moles of NBr3 will react with = (40 x 3)/2 = 60 moles of NaOH.
From the above calculations,
A higher amount of NaOH i.e 60 moles than what was given from the question i.e 48 moles is required to react completely with 40 moles of NBr3. Therefore, NaOH is the limiting reactant and NBr3 is the excess reactant.
It would need 47 electrons
