With the given formula, we can calculate the amount of CO₂ using the balance equation but we first need the moles of CH₄
1) to find the moles of CH₄, we need to use the ideal gas formula (PV= nRT). if we solve for n, we solve for the moles of CH₄, and then we can convert to CO₂. Remember that the units put in this formula depending on the R value units. I remember 0.0821 which means pressure (P) has to be in atm, volume (V) in liters, the amount (n) in moles, and temperature (T) in kelvin.
PV= nRT
P= 1.00 atm
V= 32.0 Liters
n= ?
R= 0.0821 atm L/mol K
T= 25 C= 298 K
let plug the values into the formula.
(1.00 x 32.0 L)= n x 0.0821 x 298K
n= (1.00 x 32.0 L )/ (0.0821 x 298)= 1.31 moles CH₄
2) now let's convert the mole of CH₄ to moles to CO₂ using the balance equation
1.31 mol CH₄ (1 mol CO₂/ 1 mol CH₄)= 1.31 mol CO₂
3) Now let's convert from moles to grams using the molar mass of CO₂ (find the mass of each atom in the periodic table and add them)
molar mass CO₂= 12.00 + (2 x 16.0)= 44.0 g/mol
1.31 mol CO₂ ( 44.0 g/ 1 mol)= 57.6 g CO₂
Note: let me know if you any question.
Answer:
Humans
Explanation:
Humans have energy of motion and store energy.
The advantages of the hydropower are:
- It is renewable
- It is a clean source of energy
- Matches current demand
- It is stable and reliable
- Requires low operating cost
The disadvantages of the hydropower are:
- Causes environmental damage
- Cost of building is expensive
- May cause droughts
- May cause floods in lower areas
- Shortage of water supply
The hydroelectric power has its prons and cons. It is very expansive for building, and it causes environmental damage in the river systems, but it also causes hazards like droughts and floods at certain areas. On the other side, once established it is very cheap, and it gets the job done when it comes to electricity. It is also an energy that is not polluting, and it is sustainable, reliable, and renewable.
Answer:
Its either B or D. I personally would go with B
Explanation:
It’s called an isotope which is an atom with the same number of protons but a different number of neutrons
