Answer:
large supply of nutrients.
Explanation:
In a wetland, the soil is covered by water or is almost covered by water. This water may be coming upwards from an underground aquifer. Wetlands are covered by water for most of the year.
They are sheltered waters and do provide habitats for many living things.
Nutrients such as; Carbon sulfur, phosphorus, carbon, and nitrogen are cycled within the soil of wetlands hence wetlands have a large supply of nutrients.
AR 385-63/MCO 3570.1C is used in conjunction with DA PAM 385-63.
AR 385-63/MCO 3570.1C is the regulation or order which provides revised range safety policy for the Army and Marine Corps.
This order/regulation applies on the Active Army or the Army National Guard of the United states.
Answer : The correct option is, (C) 2, 4 and 5.
Explanation :
Combustion reaction : It is a type of reaction in which a hydrocarbon react with an oxygen molecule to give carbon dioxide, water as a product.
For example : Methane react with oxygen to give carbon dioxide and water.

In the given list of chemical substances,
are in oxide form. They can not be both reactant and product of a single combustion reaction.
In the given list,
is the only hydrocarbon which shows a combustion reaction. That means
react with
to give
and
as a product.
The balanced combustion reaction of
is,

Therefore, the correct answer is, (C) 2, 4, and 5.
The answer is C because there are 22 oxygen atoms on the product side so to balance the equation the coefficient needed is 11
The mole fraction of acetone (C₃H₆O) is 0.333
<h3>Data obtained from the question </h3>
- Mole of C₃H₆O = 0.1 mole
- Mole of CHCl₃ = 0.2 mole
- Mole fraction of C₃H₆O =?
<h3>How to determine the mole fraction </h3>
Mole fraction of a substance can be obtained by using the following formula:
Mole fraction = mole / total mole
With the above formula, we can obtain the mole fraction of C₃H₆O as follow:
- Mole of C₃H₆O = 0.1 mole
- Mole of CHCl₃ = 0.2 mole
- Total mole = 0.1 + 0.2 = 0.3 mole
- Mole fraction of C₃H₆O =?
Mole fraction = mole / total mole
Mole fraction of C₃H₆O = 0.1 / 0.3
Mole fraction of C₃H₆O = 0.333
