Answer:
the second choice
Explanation:
hi! im not 100% sure but i do think its particles close together and moving past each other ( the 2nd choice) sorry its wrong
Explanation:
Formula to calculate standard electrode potential is as follows.
= 0.535 - 1.065
= - 0.53 V
Also, it is known that relation between and K is as follows.
ln K =
Substituting the given values into the above formula as follows.
ln K =
=
ln K = -41.28
K =
=
Thus, we can conclude that the value of the equilibrium constant for the given reaction is .
Answer:
CaCO3
Explanation:
The molecule is formed by the calcium cation Ca+2 and the carbonate anion CO3−2.
Keeping the masses of the objects unchanged, if the distance between the objects is halved, then the magnitude of gravitational force between them will become. Hope this helps please mark brainliest :)
Explanation:
Formula to calculate the atomic packing factor is as follows.
APF =
=
It is given that atomic radius is 0.123 nm and density of metal is 7.45 .
Hence, number of atoms will be calculated as follows.
No. of atoms = = 4
APF =
= 1.3905
Thus, we can conclude that atomic packing factor if the unit cell has a tetragonal symmetry is 1.3905.
