A sandblasted rock differs from a non-sandblasted rock in various aspects, including a change in texture and color of the rock's surface.
Sandblasting is a process in which a high-pressure stream of sand or other abrasive material is used to remove material from the surface of an object.
The most noticeable difference between a sandblasted rock and one that hasn't been sandblasted is the texture of the surface. A sandblasted rock will typically have a rough, pitted surface, while an unsandblasted rock will have a smoother surface.
Sandblasting can also change the color of a rock. If the rock has a layer of surface material that is a different color than the underlying rock, sandblasting can remove the surface layer and expose the underlying rock.
Therefore, a sandblasted rock would differ from a rock that hasn't been sandblasted in several ways such as change in texture and color of a rock's surface, creating a rough, pitted texture and exposing the underlying rock.

Answer:
1s2 2s2 2p6 3s2 3d5 is a pseudo-noble-gas electron configuration
Explanation:
It is the technetium with atomic number 43. Being the lightest element having isotopes with all radioactive and no one are more stable as compared to that of technetium which is in fully ionised state i.e. 97 Tc. This element is mostly used for gamma ray emission in medical treatment. Also found to be used as corrosion inhibitor in case of steel, when present in small amount gives better result. This metal is silver grey colour that is found to discoloration when comes in contact with moist air. Its isotopes are radioactive.
Answer:
1s2 2s2 2p6 3s2 3p6 3d10
Explanation:
A pseduo noble gas configuration refers to charged species with electron configurations that are almost identical to that of one of the noble gases.
The noble gas (n-1)d^10 (where n refers to the principal quantum number of the outer s orbital) configuration of ions is commonly known as a pseudo noble gas configuration. The configuration stated in the answer is for Cu^+ ion. n in the case of Cu^+ ion is 4(since copper metal has a 4s1 level).
Note that; 1s2 2s2 2p6 3s2 3p6 is the electron configuration for argon, followed by 3d^10. Hence our definition for a pseudo noble gas.
Answer:
2
Explanation:
There are at least 2 atoms in a molecule
B.meiosis
C.photosynthesis
D.mitosis
Answer:
The correct answer is A.respiration
Explanation:
Cellular respiration is a process which produces ATP (adenosine triphosphate) and methabolites. ATP is an "energy coin" which provides energy for biochemical processes in all cells. The other options are not correct: meiosis is the division process of sexual cells, mitosis is the division process of somatic cells and photosynthesis ocurrs in plant cells to obtain energy (not in animal cells of muscle tissue).
