Answer:
Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.

28.0 x 0.6424 = 18
25.0 x .6424 = 16.1
Mass = 34.1
a. Hydrogen
Hydrogen has a line at 410 nm.
Mercury has a line at 405 nm.
Sodium and neon have no lines near 412 nm.
The answer is buffers.
Chemicals called buffers are those that can combine with H⁺ when hydrogen ions are in excess, and release H⁺ when hydrogen ion levels are low. the function of these chemicals is to minimize changes in pH.
Buffers are the substances that resist change in its pH on addition of small volume of acid and base.
