Answer:
A compound containing metallic bonds.
Explanation:
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,
%

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:

Answer:
protons, nuetrons, electrons
Explanation:
compounds and electrons are made up of atoms.
Percent composition by mass is calculated (mass of element within compound)/(mass of compound)*100. The lower the total molar mass of the compound, the greater the percent composition of sulfur. In this case, MgS would be that compound, since Mg has the lowest molar mass of the four elements bonded to S.
Answer:
The strength of an acid or alkali depends on the degree of dissociation of the acid or alkali in water. The degree of dissociation measures the percentage of acid molecules that ionise when dissolved in water. He could use universal indicators or litmus paper for this.
