i believe the answer would be c
the the compound of interest i.e. xcl4, since there are 4 cl atoms bonded to x. this signifies that the valency of x is 4.
there atomic number of c is 6. it's electronic configuration is giving by 1s2 2s2 2p2. thus, there are 4 electrons in valence shell of c. this signifies that valency of c is 4. hence the compound present in present case is ccl4.
hope this : )
- because there is an inverse relation between altitude and the number of gas molecules striking the outer surface of the bottle (pressure exerted on it).
- therefore, when the bottle is taken to lower altitude, the number of gas molecules striking the outer surface of the bottle increases and so changing its shape..
the correct answer is option d, that is low growing.
