Answer:the fractional conversion of methane is 12.5%
Explanation:The reaction represent the combustion of methane to produce Co2 and steam.
CH4 +2O2_CO2 + 2H2O
From gay lussac law of proportionality
1mol of CH4 requires 2mol of Oxygen to produce 1 mol of CO2 and 2mol of H2O
So from the combining ratio,25% of O2 will fractional produce 25×1/2% of CH4.
While 12.5% of CO2 and 25% of steam is also produced .so in essence 2.5% of CO2 was lost in the reaction.
Answer:
I believe the correct answer would be Weight.
Weight is a force that gravity exerts on an object.
Hope this helped :))))
Answer:
t ≤ 0.31s
Explanation:
Given
Frequency = 0.1Hz
Dynamic Error:
σ = 1 - M(σ)
From the question
σ= 1 - M(σ) ≤ 2%
1 - M(σ) ≤ 0.02
The above corresponds to
M(σ) = 1/(1 + (wt))² ≥ 100% - 0.02
M(σ) = 1/(1 + (wt))² ≥ 1 - 0.02
M(σ) = 1/(1 + (wt))² ≥ 0.98
Since frequency = 0.1Hz
w = 2πf =
w = 0.628571428571428
w = 0.628rads
So, M(0.628) = 1/(1 + (0.628t)²) ≥ 0.98
Solving 1/(1 + (0.628t)²) ≥ 0.98 we get that
t ≤ 0.31s

Answer:
(C) The volume of an atom is mostly empty space.
Explanation:
Rutherford's nuclear theory:
Rutherford's performed an experiment with the help of alpha particle and gold foil film.By doing this experiment he concluded that
1.Mass and charge of an atoms is located in the nucleus.
2.Nucleus are surrounding by electron .Nucleus is a positive charge particle and electron is a negative charge particle.
According to Rutherford's nuclear theory,the volume of an atom is mostly empty space.
So option C is correct.
(C) The volume of an atom is mostly empty space.
