Answer:
Option C
Explanation:
Dipole moment being ac vector quantity has both magnitude and direction. All bonding forces have dipole moment ranging from partially positive to negative moment.
Net dipole moment is the dipole moment arising after summation of all the existing dipole moments. On the basis of dipole moment it is determined whether the molecule is polar or non polar.
Hence, option c is correct
Answer:
Explanation:
OK this is simple
i'll try to do the unanswered question
CaCl2
In the table
You look for calcium,Ca you fill 1
THen for Chloride=2
i hope you've understood
Explanation:
It is known that relation between Gibb's free energy and equilibrium or reaction quotient is as follows.
..... (1)
At equilibrium, = 0. Also, Q = K this means that reaction is at equilibrium.
Therefore, formula in equation (1) will become as follows.
....... (2)
It is known that for a sparingly soluble salt, K =
Thus, equation (2) will become as follows.
....... (3)
So, when value of increases then there will be decrease in the value of according to equation (3).
Hence, we can conclude that the calculated value of would be too big.
Convert 55.0g Ca(OH)2 to mols.
55.0g Ca(OH)2 = 0.742 mols Ca(OH)2
0.742mol Ca(OH)2/ 0.680M Ca(OH)2 = 1.09L Ca(OH)2
Neglecting the volume of the Ca(OH)2 itself, since it is minimal and its density wasn't provided, 1.09L would be the total volume of a 0.680M solution produced by dissolving 55.0g of Ca(OH)2 in enough water.
Answer:
Rate law:
Integrated Rate Law:
Explanation:
We can see that the graph of time is linear compared to and the reaction is second order hence we get the rate law from .
The integrated rate law for second order is where A is .
The slope of the graph w.r.t time is equal to k. The slope of the graph from the table is 0.014 which is equal to k.
