By the use of the Nernst equation, the concentration of the lead solution is 4.8 * 10^-8 M.
What is Nernst equation?The Nernst equation is the equation that is used to obtain the EMF of a cell under non standard conditions.
Now;
E°cell = -0.01 V
Ecell = 0.21V
[sn2+] = 1.30 M
[pb2+] = ?
From;
Ecell = E°cell - 0.0592/n logQ
The equation is; Sn^+ + Pb ----> Sn(s) + Pb^2+
0.21 = -0.01 - 0.0592/2 log(x/1.30 )
0.21 + 0.01 = -0.0592/2 log(x/1.30 )
0.22/-0.0296 = log(x/1.30 )
-7.43 = log(x/1.30 )
Antilog(-7.43) = x/1.3
x = 4.8 * 10^-8 M

Now cut the two remote interior angles and paste it on the exterior angle
An example of remote interior angles on the exterior angle is given in the images attached.
What Is a Remote Interior Angle?A remote interior angles are known to be those angles that do not have or do not share the same vertex or corner of a triangle with that of an exterior angle.
Note that a remote interior angles are known to be the two angles that are said to be inside the triangle and thus it is often opposite the exterior angle (see image)
See full question below
Using a piece of paper, follow the instructions below.
1. Draw a triangle and name it as ABOD
2. Put point Y on the right side of the triangle.
3. Extend line segment OD to point Y.
4. Identify the exterior angle of the triangle and its two remote interior angles.

Which function is continuous at x = 18? f (x) = startfraction (x minus 18) squared over x endfraction f (x) = startfraction x squared minus 17 x minus 18 over x minus 18 endfraction f (x) = tangent (startfraction pi over 36 endfraction x) f (x) = startlayout enlarged left-brace first row x squared, x not-equals 18 second row 36, x = 18 endlayout
The function that is continuous at x = 18 is:
y = (x - 18)/x
Which function is continuous at x = 18?
We need to see which function has no problems when x = 18.
For example, the first one:
y = (x - 18)/x
When x = 18, we have:
y = (18 - 18)/18 = 0
Then this function is continuous at x = 18.
When, for the second option, we have (x - 18) on the denominator, and then when x = 18 the denominator becomes 0, so that function is not continuous at x = 18.
With that, we conclude that the correct option is the first one.

Food chains represent oversimplifications of producer-consumer relationships. indicate if the following statements about interactions among trophic levels are true or false in explaining the complexity of these interactions.
Answer:
The statement "Food chains represent oversimplifications of producer-consumer relationships" is true.
Explanation:
Food chains are linear representations of the flow of energy and nutrients through an ecosystem. They typically involve a single pathway of energy transfer from producers (plants) to primary consumers (herbivores) to secondary consumers (carnivores or omnivores) and so on. However, in reality, ecological interactions are much more complex and interconnected.
In natural ecosystems, food webs are more accurate representations of the trophic interactions. Food webs consist of multiple interconnected food chains, showcasing the various feeding relationships and interactions among different species within an ecosystem. They include multiple producers, consumers at different trophic levels, and decomposers, creating a complex network of energy flow.
Food chains can be useful as simple models to understand basic energy flow patterns, but they do not fully capture the intricacies and complexities of the actual interactions in an ecosystem. In contrast, food webs provide a more comprehensive picture of how energy, nutrients, and interactions are shared and exchanged among species, making them more accurate representations of the relationships in an ecosystem.
