Answer:
I'm pretty sure its the one that says very little at the beginning but if I get it wrong I'm sorry
The scientist who studies the earth constituent like solids, gas and liquid is called a geologist. Weathering and erosion are the correct blanks.
<h3>What are weathering and erosion?</h3>
The process of the deterioration of any solid particles like minerals, soils and rocks is called weathering. It occurs due to biochemical substances, atmospheric gases and water pressure.
The process of the transportation of the rocks and mineral particles away from their original position is called erosion it is due to forceful air and water.
The rocks moved from their original place to some another due to weathering and this process of their transportation is called erosion.
Therefore, <u>weathering </u>and <u>erosion </u>are the correct blanks.

Answer: 292.54g of Ag
Explanation:
Cu + 2AgNO3 →Cu(NO3)2 + 2 Ag
mass conc. Of Ag = n x molar Mass
Mass conc. Of Ag = 2 x 108 = 216g
From the equation,
63.5g of Cu produced 216g of Ag
Therefore, 86g of Cu will produce Xg of Ag. i.e
Xg of Ag = (86 x 216)/63.5 = 292.54g
Answer: Structural Isomers
Explanation:
The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.
Isomers are of two types: structural isomers and stereo isomers.
Structural isomers are isomers in which molecules with the same molecular formula have different bonding patterns.
Stereoisomers are isomers in which molecules have the same molecular formula and sequence of bonded atoms but differ in the three-dimensional orientations of their atoms in space.
Thus when molecules have the same number of each element but those atoms are arranged differently they are known as Structural isomers.
