Answer:
A strong base produces more ions in solution than a weak base.
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, 
%
%
- 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:
The list of options to answer this question is:
A.kinectic energy is transformed into thermal energy.
B.electrical energy is transformed into potential energy.
C.potential energy is transformed into kinectic energy.
D.mechanical energy is transformed into chemical energy.
The answer is the option A. A.kinectic energy is transformed into thermal energy.
As you know energy cannot be lost but transformed.
When friction force acts over the tyres it increases the speed of the particles in the tyres which is thermal energy, this thermal energy increase comes from kinetic energy loss.
Answer:
In the Lewis structure for IF5 you'll need to put a total of 12 valence electrons on the Iodine atom in order to draw the Lewis structure. Remember that Iodine (I) can hold more than eight valence electrons. For the IF5 Lewis structure, calculate the total number of valence electrons for the IF5 molecule

You can define an element as a substance with only one type of atom in
(e.g. only sulphur atoms). If a substance has more than one type of atom
in, then it is either a compound or a mixture, depending on whether the
elements have bonded. Examples of elements are:
Oxygen
Sulphur
Carbon
Hydrogen
Protactinium
Compound-
A substance made up of atoms of two or more different elements joined by chemical bounds.
Molecule- a pure substance that cannot be broken down
Salt- A Ionic Compound Formed From The Reaction Of An Acid And Base .
