Answer:
7200 kPa
Explanation:
Applying,
PV/T = P'V'/T'................ Equation 1
Where P = Initial pressure of neon gas, V = Initial volume of neon gas, T = Initial temperature of neon gas, P' = Final pressure of neon gas, V' = Final volume of neon gas, T' = Final Temperature of neon gas
Make P' the subject of the equation
P' = PVT'/V'T.............. Equation 2
Given: P = 900 kPa, V = 8.0 L, T = 300 K, V' = 2.0 L, T' = 600 K
Substitute these values into equation 2
P' = (900×8×600)/(2×300)
P' = 7200 kPa
Answer:
Q= 0.21472 C
Explanation:
current is the rate of flow of charge through a wire or a circuit.
I = Q/t
Where I is current
Q is charge
t is time
Q=It
from the question, I=0.52 A , t=411 milliseconds
Q = 0.52 *411*
Q= 0.21472 C
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Explanation:
In the combustion reaction methane (CH₄) will react with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O).
CH₄ + O₂ → CO₂ + H₂O
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
So the balanced chemical reaction will be:
CH₄ + 2 O₂ → CO₂ + 2 H₂O
