Answer:therefore the oxidation state of sulphur is +6 in the compound CaSO4.
Explanation:
Answer : The absolute permeability is, 0.111 darcys.
Explanation : Given,
Volumetric constant rate = 
Cross section area = 
Pressure = 2 atm
Viscosity = 1.0 cp
Length of rock = 4 cm
From the Darcy equation we conclude that,
where,
A = cross section area
P = pressure
= viscosity
l = length of rock
Now put all the given values in the above formula, we get:
Therefore, the absolute permeability is, 0.111 darcys.
B, you can see there are 2 F atoms on each side of the equation
Answer:
250 mmol are left after 26.60 secs ≅ 26.6 seconds
Explanation:
zero order kinetics formula is:
[A] = [A₀] - kt
where [A] = amount left; [A₀] = amount remaining; k = rate constant; t = time
concentration [A₀] = mole/volume = 0.5 mole/2.0L = 0.25
[A] = 0.25 mole/2.0L = 0.125 M
k = 0.0047 Ms⁻¹
t = {[A]-[A₀]}/-k = (0.125 - 0.25)/(-0.0047) = 26.60 seconds = 26.6 seconds
the amount is reduced by half after 26.6 seconds
Put a thermometer in the water and wait until it boils. When it boils record the temperature and compare it to the normal water boiling point.
