Formation of Sedimentary RocksLast Updated on Tue, 15 Mar 2016 | Geology
N^deS Sediments produced by weathering and erosion form sedimentary rocks through the process of lithification.
Real-World Reading Link Whenever you are outside, you might see pieces of broken rock, sand, and soil on the ground. What happens to this material? With one heavy rain, these pieces of broken rock, sand, and soil could be on their way to becoming part of a sedimentary rock.
Weathering and Erosion
Wherever rock is exposed at Earth's surface, it is continuously being broken down by weathering—a set of physical and chemical processes that breaks rock into smaller pieces. Sediments are small pieces of rock that are moved and deposited by water, wind, and gravity. When sediments become glued together, they form sedimentary rocks. The formation of sedimentary rocks begins when weathering and erosion produce sediments.
Weathering Weathering produces rock and mineral fragments known as sediments. These sediments range in size from huge boulders to microscopic particles. Chemical weathering occurs when the minerals in a rock are dissolved or otherwise cimicly changed. What happens to more-resistant minerals during weathering? While the less-stable minerals are chemically broken down, the more-resistant grains are broken off of the rock as smaller grains. During physical weathering, however, minerals remain chemically un changed.
Answer: heck the chemistry app itll help you i dont know this answer but the app will tell u!
2M
Explanation:
Given that:
V1 = 50mL
M1 = 40M
V2 = 1000mL
unknown:
M2 = ?
Solution:
Concentration is the number of moles solute in a solution.
Since the number of moles in the solute remains the same;
Concentration = 
number of moles = concentration x volume
Number of moles before and after the dilution remains the same;
M1 x V1 = M2 x V2
M1 is initial concentration
V1 is initial volume
M2 is final concentration
V2 is final volume
40 x 50 = M2 x 1000
M2 = 2M

Answer:
96.3%
Explanation:
Data obtained from the question include:
Theoretical yield = 54g
Actual yield = 52g
Percentage yield =..?
The percentage yield can be obtain as follow:
Percentage yield = Actual yield /Theoretical yield x 100
Percentage yield = 52/54 x 100
Percentage yield = 96.3%
Therefore, the percentage yield of the reaction is 96.3%
