Answer:
Explanation:
The lewis structure (indicating all the atoms and patterns provided as hint in the question) of glycine can be seen in the attachment below. While the chemical structure of glycine can be seen below

H OH
The structure (of glycine) above provides a "fair idea" of how the lewis structure will be.

Answer:- 0.134 seconds
Solution:- The speed is given as and the circumference is 24900 miles which is same as the distance light have to covered. It asks to calculate the time required to cover this distance by the light.
We need to do unit conversion from miles to meter as the speed is given in meter per second.
1 mile = 1609.34 meter
So,
= 40072566 meters
Know that,
It's rearranged to time as,
Let's plug in the values in it:
= 0.134 seconds
So, the light would take 0.134 seconds to travel the mentioned speed. The answer without the unit is 0.134.
Answer:
Explanation:
Hello!
In this case, since the dissolution of copper (I) chloride is:
And its equilibrium expression is:
We can represent the molar solubility via the reaction extent as , however, since there is 0.050 M KCl we immediately add such amount to the chloride ion concentration since KCl is readily ionized; therefore we write:
Thus, solving for , we obtain:
By using the quadratic equation, we obtain:
Clearly, the solution is because no negative results are
allowed. Therefore, the molar solubility is:
