Two mixed cylinders have exactly the same volume. Cylinder A has a higher fraction of Al than cylinder B. Is the mass of cylinde r A greater than, less than, or equal to the mass of cylinder B?
1 answer:
Answer:
Explanation:
Cylinder A has a higher fraction of Al (Aluminum) than cylinder B. The mass of cylinder A will be greater than cylinder B because the density of Al which cylinder A contains higher fraction of compare to cylinder B is denser than air with Al having about 2,710 kg / m³ density and air having 1.225 kg / m³

Answer:
PV=nRT
Explanation:
V=<u>R</u><u>T</u><u>n</u>
P
rearrangement gives
nT
where P=pressure
V=volume
n=number of moles
R=ideal gas(0.0820atmdm/3 mol/k)
T=temperature in kelvin
Answer:
0.049 mol/L.s
Explanation:
The decomposition of hydrogen peroxide is:
The rate of decomposition reaction = the rate of formation of = 0.098 mol/L.s
∴
Rate of formation of
= 0.049 mol/L.s
