Answer:
D. 5.6 g/cm^3
Explanation:
On the average seismic velocity increases with increase in depth due higher the pressure and more compaction
sand and shales in the Niger Delta Basin density–velocity relationship is
P = 0.31×V^0.25
A derivation of the original Gardner equation to calculate the average densities for sands and shales in wells.
ρ = α ×V^β
where
ρ = bulk density in g/cm3,
V = P-wave velocity,
α = 0.31 for V (m/s) and 0.23 for V(ft/s) and
β = 0.25.
Such that
ρ = 0.31 ×V^0.25
So the fastest seismic velocity will be in the densest material which is D. 5.6 g/cm3
Answer:
The answer to your question is: 65.9 g released of CO2
Explanation:
MW CO2 = 44 g
MW CuCO3 = 123.5 g
CO2 released = ?
CuCO3 = 185 g
CuCO3 ⇒ CO2 + CuO
123.5 ----------- 44g
185 g ----------- x
x = (185 x 44) / 123.5
x = 65.9 g released of CO2
Answer:
c) has an irritating odor and is colorless
Explanation:
Sulfur dioxide refers to a gas. It has a nasty, sharp smell and is invisible. It associates with other components to produce harmful compounds like sulfurous acid, sulfuric acid, and sulfate particles. It is the chemical compound with the formula SO. At standard temperature, it is a toxic gas with an irritating and pungent smell. The gas is released naturally by the volcanic activity.
I'm pretty sure that the answer is B.
