#13.) For the reaction CH4 + 2O2 → CO2 + 2H2O, how many moles of carbon dioxide are produced from the combustion of 161.0 g of methane?
Select one:
a. 10.03
b. 20.06
c. 2584
d. 3.351
Answer 1)Option A) 58.05
In the given reaction of iron forming rust when reacts with the oxygen.
We can clearly see that, 4 moles of iron reacts with 3 moles of oxygen to give 2 moles of iron oxide.
So 4 Fe : 3 O and 77.4 moles of Fe : x moles of O
(3 X 77.4) / 4 = 58.05
So when we solve we get x as 58.05.
Hence the no. of moles of oxygen will be 58.
Answer 2) Option A) 10.03
The number of moles of carbon dioxide produced when 161.0 g of methane undergoes combustion will be 10.03
as we know the molar mass of methane is 16.043g
As we can see in the reaction the mole ratio is 1:1;
1 mole of methane produces 1 mole of carbondioxide.
So, 161 g / 16.043 g = 10.03 moles of Carbon dioxide.
A strong acid is safe as long as it's in a dilute solution

Explanation:
The computer monitor powered by electricity that has been generated by a wind turbine involves several types of energy.
The types of energy involved are as follows:
1. Kinetic energy:The blades of the wind turbine rotate and move due to the force of the wind. This motion or movement of the blades is referred to as kinetic energy.
2. Mechanical energy:The kinetic energy of the wind is converted into mechanical energy as the blades of the wind turbine rotate. This mechanical energy is then transferred to a generator which converts it into electrical energy.
3. Electrical energy:The mechanical energy from the wind turbine is converted into electrical energy by the generator. This electrical energy is then transferred to the computer monitor via electrical wires.
4. Potential energy:As the wind turbines blades move, they gain potential energy. The potential energy is the energy that an object has due to its position or condition. The blades of the wind turbine gain potential energy as they move higher and higher due to the wind force. This potential energy is converted into kinetic energy as the blades rotate.
Thus, there are 4 types of energy involved in computer monitor powered by electricity that has been generated by a wind turbine.
