Answer:
An unconformity is a widespread surface separating rocks above and below, which represents a gap in the rock record. Unconformities occur when either erosion wears away rocks, or rock deposits never form. Therefore, a time gap exists between when the rocks below the unconformity formed and when those above it formed.
Explanation:
Answer:
The answer to your question is 1.25 M
Explanation:
Data
Molarity 1 = ?
Volume 1 = 60 ml
Molarity 2 = 0.5 M
Volume 2 = 150 ml
Process
1.- Write the dilution formula
Molarity 1 x Volume 1 = Molarity 2 x Volume 2
-Solve for Molarity 1
Molarity 1 = Molarity 2 x Volume 2 / Volume 1
-Substitution
Molarity 1 = (0.5)(150) / 60
-Simplification
Molarity = 75 / 60
-Result
Molarity = 1.25 M
FeO + Al -> AlO + Fe
As you can see, this type of reaction would lead to be a Single Placement (or Replacement) reaction!
Hope this helps! Best wishes!
Density will be mass/volume= 0.2/500 = 0.0004
