Let a, b, and c be the coefficients in the balanced reaction:
a Fe + b Cl₂ → c FeCl₃
Count the atoms that show up among the reactants and products. They should be equal on both sides:
Fe : a = c
Cl : 2b = 3c
Let c = 2. Then a = 2 and 2b = 6, so b = 3.
Then the balanced reaction is
2 Fe + 3 Cl₂ → 2 FeCl₃

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

Explanation:
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.
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.

Researchers designed an experiment to test the hypothesis that the evolution of coloration in lice is driven by birds. researchers transferred 25 lice from a random sample of lice obtained from wild‑caught rock pigeons to each individual in groups of black pigeons and white pigeons. half of the pigeons from each color group were fitted with a harmless mouthpiece that stopped the beaks from entirely closing. the mouthpiece prevented pigeons from removing lice but did not affect the pigeons’ ability to feed. each pigeon was isolated and kept in identical environmental conditions for temperature, humidity, and amount of light. the lice have a generation time of 24 days. the researchers observed the phenotypes of the lice over a period of four years.
Phenotypic variation in louse body color in a population of lice would make it difficult for the louse to be spotted and picked off any pigeon's feathers.
What is phenotypic variation?Phenotypic variation can be defined as the difference (variability) in the observable characters or attributes (phenotypes) of each organism in a specific population.

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
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
