Atoms in covalent bonds do combine so as to be stable. As covalent bond consist non metals e.g O2 in this example each atom has vacance of 2 orbitals/ electrons so shairing electrons result their stability
173.1f is the answer I believe, please let me know if I'm wrong then I would try to make up for it
Answer:
7.35atm
Explanation:
Data obtained from the question include:
V1 = 28L
T1 = 42°C = 42 + 273 = 315K
P1 =?
V2 = 49L
T2 = 27°C = 27 + 273 = 300K
P2 = 4atm
Using P1V1/T1 = P2V2/T2, the original pressure can be obtained as follows:
P1V1/T1 = P2V2/T2
P1 x 28/315 = 4 x 49/300
Cross multiply to express in linear form
P1 x 28 x 300 = 315 x 4 x 49
Divide both side by 28 x 300
P1 = (315 x 4 x 49) /(28 x 300)
P1 = 7.35atm
Therefore, the original pressure is 7.35atm
Answer:
d. when atoms are situated in a repeating array over large atomic distances.
Explanation:
A crystalline material -
It refers to the type of solid substance where the atoms or ions are arranged in a very orderly fashion , composing a well designed lattice , is referred to as crystalline material .
These type of substances are studied under a special subtopic known as crystallography .
Hence , from the given information of the question ,
The correct option is d.
