a. Elemental percent composition is the mass percent of each element in the compound.
The formula for mass elemental percent composition = 
(1)
The molecular formula of cisplatin is 
.
The atomic weight of the elements in cisplatin is:
Platinum, 
Nitrogen, 
Hydrogen, 
Chlorine, 
The molar mass of = 
= 
The mass of each element calculated using formula (1):
- Platinum, 
%

b. The given reaction of cisplatin is:
According to the balanced reaction, 1 mole of 
gives 1 mole of .
Now, calculating the number of moles of in 100.0 g.
Number of moles = 
Molar mass of = 
Number of moles of = 
.
Since, 1 mole of gives 1 mole of . Therefore, mass of cisplatin is:
For mass of 
:
Molar mass of = 
Since, 1 mole of gives 2 mole of . Therefore, mass of is:
A risk-benefit analysis compares the risks and benefits of a situation and determines whether the advantages outweigh the disadvantages.
<h3>What is Risk-benefit analysis in technology?</h3>
Strengths
Risk-benefit analysis calculates the amount of time will be worth it to the production of technology and whether the technology will have a healthy impact on the industry or not.
Weaknesses
Risk-benefit analysis cannon determine product implementation and the outcomes of real life experiences of individual customers. It has some drawbacks like benefits of customer is take under consideration but pollution in nature is not calculated.
Implication
Risk-benefit analysis is implied in almost all technical industry as it the decision maker of any developing team to work on a particular project or not. Some examples are automobile industry and smartphone industry.

Answer:
3 bonds are needed.
Explanation:
The electrons that are involved in chemical bonding are those in the outer shell of the highest energy level of the atom. The electron configuration of nitrogen (N) is 1s²2s²2p³. That means thy at each nitrogen atom has 5 valence electrons: 2 electrons in the 2s orbital and 3 electrons in the 2p orbital. To fullfil the octet, each nitrogen atom needs 3 electrons. So, they can share each other 3 electrons to form 3 simple bonds. Therefore, the nitrogen molecule (N₂) has 3 bonds involving 6 bonding electrons or a triple bond.
Answer: I would say its either exit door or the last one.
Explanation: Hope this helps plz mark brainliest.
1,3-pentadiene has two double bonds which are conjugated, which undergo electrophilic addition reaction on reacting with 
.
The structure of 1,3-pentadiene is shown in the image.
When strong acid such as reacts with 1,3-pentadiene, the electrophilic addition reaction can occur either on double bond at 1,2-position or at 3,4-position. The reaction that occurs is shown in the image.
