For the galvanic (voltaic) cell fe(s) + mn²⁺(aq) ⟶ fe²⁺(aq) + mn(s) (e° = 0.77 v at 25°c), what is [fe²⁺] if [mn²⁺] = 0.050 m and e = 0.78 v? assume t is 298 k

Answers

The concentration of Iron in the galvanic (voltaic) cell Fe(s) + Mn²⁺(aq) ⟶ Fe²⁺(aq) + Mn(s) is 0.02297 M.

What is the Nernst Equation?

The Nernst equation enables us to identify the cell potential(voltage) in presence of non-standard conditions in a galvanic cell. It can be expressed by using the formula:

[tex]\mathbf{E_{cell} = E_o - \dfrac{0.059}{n} \times log \dfrac{[Fe^+]}{[Mn^{2+}]}}[/tex]

where;

n = Number of electrons = 2[tex]\mathbf{E_o}[/tex] = Initial voltage = 0.77 V[tex]\mathbf{E_{cell}}[/tex] = Cell voltage = 0.78 V[tex]\mathbf{[Mn^{2+}]}[/tex] = Manganese concentration = 0.050 M

Replacing the values into the above equation, we have:

[tex]\mathbf{0.78 = 0.77 - \dfrac{0.059}{2} \times log \dfrac{[Fe^{2+}]}{[0.050]}}[/tex]

[tex]\mathbf{0.78 -0.77= -0.0296\times log \dfrac{[Fe^{2+}]}{[0.050]}}[/tex]

[tex]\mathbf{log^{-1} (-0.3378) = \dfrac{[Fe^{2+}]}{[0.050]}}[/tex]

can someone write a 1200 word essay for my explaining why plants are important i dont really know how to do this and i need help.

Answers

Answer:

Plants provide us with food, fiber, shelter, medicine, and fuel. The basic food for all organisms is

produced by green plants. In the process of food production, oxygen is released. This oxygen, which we

obtain from the air we breathe, is essential to life. The only source of food and oxygen are plants; no

animal alone can supply these. Shelter, in the form of wood for houses; and clothing, in the form of

cotton fibers, are obvious uses of plant materials. But we must not forget fuel, furniture, paper

products, certain medicines like aspirin, and many other products like perfume and chewing gum. To

these tangible aspects of the plant world we must also add the importance of beauty and relaxation

derived from plants. Since animals are surrounded by and dependent upon plants, the factors that

influence plant growth, structure, and distribution, affect the animal world as well.

Plant - Animal Relationships

Forests, lawns, streams, and marshes are all habitats that are easily recognized as unique biotic

communities. A community is a naturally occurring, interactive assemblage of plants and animals living

in the same environment. The interaction between plants and animals often exists out of the need for

food, protection, transportation, and reproduction. The different kinds of interaction possible between

organisms are extremely important in determining the abundance of species. If the interaction between

species is beneficial, it is described as mutualism. Some of the most complex mutualistic relationships

evolved between plants and pollinators. If the interaction proves disadvantageous, it is referred to as

competition. Commensal relationships, in which one species benefits and the other is unaffected, are

common between plants and animals. For example, when a bird builds a nest in a tree, the bird benefits

and the tree is (usually) unharmed. Other relationships may positively affect one population and be

detrimental to the other. Such relationships involve predation and parasitism. In predation, one

organism directly kills and consumes its prey. Parasitism differs in that parasites live on or in the prey,

but may not kill it outright. A good example of parasitism is mistletoe growing on a tree.

Ecosystems

An ecosystem is the biotic (living) and abiotic (nonliving) factors

of an ecological community considered together. Ecosystems contain

four components: the physical environment (abiotic), living things

(biotic), energy input and use, and nutrients that cycle between the

biotic and abiotic components. Based on this definition, ecosystems

can vary from large unbroken tracts of forest to small ephemeral ponds

to backyards.

Calculate the average change of dissolved oxygen per year in the lake over the course of the study

Answers

The average change of dissolved oxygen per year in the lake over the course of the study is;  0.11 mg/L

What is dissolved oxygen?

Dissolved oxygen is defined as the amount of oxygen gas that is present dissolved in a given volume of water as a solution.

Dissolved oxygen is very important for aquatic animals as it provides the main source of oxygen required for respiration by these animals.

Due to human activities arising from water pollution and heating of water bodies, the amount of dissolved oxygen in water bodies is on the decrease.

To calculate the average change of dissolved oxygen per year in a particular lake, the formula is;

Average change of dissolved oxygen per year = total change over the years/total number of year

Average change of dissolved oxygen per year = (8.6 mg/L - 3.3 mg/L)/(2014 - 1965) = 0.11 mg/L

From density tables, we will discover that the density of alkynes is lower than the density of water. Likewise, the densities of alkenes and aromatic hydrocarbons are as well lower than the water.

Now those compounds are insoluble in water because they have non polar characteristics and are also lighter than water due to the fact that their density is lower than water and as such they are insoluble in water.

Building sheep pens : darsh and darpan are fencing off a large rectangular area to build some temporary holding pens. to prep the males, females, and kids, they are separated into three smaller and equal-size pens partitioned

Answers

The larger rectangle will be a square with sides of 96 ft while the pens will have 96 ft of length and 31 ft of width

How to Maximize Area of rectangle?

The side lengths of the big rectangle are x and y and so we have the following expression for its area A:

A = x*y

This is tied to the constraint that the perimeter should not be larger than the available fencing , Thus;

2x + 2y = 384   (All the fencing is used to maximize the area)

y = (384 - 2x)/2

y = 192 - x

Put 192 - x for y in A to get;

A = x(192 - x)

A = 192x - x²

Completing the square gives;

A = 9216 - (x - 96)²

Thus;

A is maximum at;

x - 96 = 0

x = 96 ft

y = 192 - 96

y = 96 ft

Then since we maximised the area of the bigger rectangle , we have maximised the area of the smaller pens. The dimensions will be;

x_small = 96 ft /3

x_small = 31 ft

y_small = 96 ft
