C3H8+ 5 O2 --> 3 CO2 + 4 H2O
44 g. --------> 72 g
33.3 g. --------> x

Answer: The theoretical yield of H2O is 54.5
Answer:
The amount of Chlorodecane in the unknown is 0.105nmols
Explanation:
a) Since the GC is in an isothermal state, Chlorohexane C6H13Cl (1.69 nmols) because of its lower boiling point will elute first and Chlorodecane C12H21Cl will elute second.
The area of the first peak corresponding to Chlorohexane is 32434 units.
The area of the second peak corresponding to chlorodecane is 2022 units.
Since the response factor of the compound is not given in question and considering the response factor is same for both the compounds, the answer will be as follow:
1.69 nmols of Chlorohexane gives 32434 units
How much of chlorodecane gives 2022 units
By cross multiplication;
Moles of Chlorodecane = 2022*1.69/32434
=0.105nmols

I think this is the right answer, but I am not sure
Answer:
Acceleration, a = 25m/s²
Explanation:
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
- m represents the mass of an object.
- a represents acceleration.
Given the following data;
Net force = 3750N
Mass, m = 150 kg
<em>Substituting into the equation, we have;</em>

3750 = 150a
a = 3750/150
Acceleration, a = 25m/s²
