Answer:
The law of conservation of mass states that mass is neither created nor destroyed but the mass of the system must remain constant over time. The total number of atoms in the reactants is equal to the total number of atoms in the product. Therefore, this chemical equation shows that energy is conserved and demonstrates the law of conservation of mass.
Answer:
It would be E. A small yellow ball that represents the Sun Reset Next i got the answer from somebody else
Explanation:
hope this helps :)
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, 
%
%.
- Nitrogen, 
%
%
- Hydrogen, 
%
%
- Chlorine, 
%
%
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:
Atomic number for bromine is 35
1. 5 ethyl, 2 methyl octane
2. 1 ethyl, 2 methyl cyclopentane
3. 3,3,5,5- tetrafluoro heptane
4. 3,4-dimethyl hexene
5. 3,4-dimethyl cyclobutene
6. 3,5 diisopropyl cyclohexene
7. 3,3,4 trimethyl pentyne
8. 2,6 dibromo phenol
keep in mind that between 4-7, there could be #1 in front of the main name. for example with #4: 3,4-dimethyl-1- hexene. this honestly depends on the professor how he/she likes it. It is not necessary because if the number is not specified, it is assumed is #1
