What mass of oxygen is needed for the complete combustion of 4.60×10−3g of methane?

sp2606 [1]

First step in answering the question is to establish a balanced chemical reaction equation. More specifically, a combustion chemical equation.

CH4 + 2O2 ---> CO2 + 2H20

Then using dimension analysis:

$4.60*10^{-3} g CH4 ( \frac{moleCH4}{16 g CH4}) * ( \frac{2mole O2}{mole CH4}) * ( \frac{32 g O2}{mole O2} ) = 0.0184 g O_{2}$

Answer:

13. c) Net

14. a) Gravity

15. d) Watt

16. b) the speed will suddenly decrease.

Explanation:

13. The net force is combination of all individual forces.

14. When we sit on the chair , then gravitational force acts on our body due to our mass.

F = mg

here, F = force due to gravity , g = acceleration due to gravity and m= mass of the body

15.Power : It is the force acting per unit area .It is discovered by James Watt

$Power =\frac{force}{area}$

$Power =\frac{N}{m^{2}}$

Its unit is $Nm^{-2}$ .In honor of the Scientist , its unit is Watt.

Watt = $Nm^{-2}$

16. When the parachute first opens , the speed of the skydiver suddenly decreases because of the resistance offered by the air particles.(For more details look at the figure attached)

17. Transfer of momentum from one object to other is the law of conservation of momentum (NOT ENERGY).So the answer is False

 Law of Conservation of Momentum :  Total momentum of a system is conserved if no external force attack on it. Momentum can neither be created nor destroyed but transferred from one form to other.
