The table compares wildlife supported by two plants growing around a lakeside ecosystem in South Florida. Plant Species and Wild

life Data Plant Species Wildlife Supported Sawgrass Alligators, Snails Melaleuca None After a 25-year period, 95% of the ecosystem was covered by melaleuca. What would be the likely impact of this on the wildlife population?

HELP PLEASE!!! Write the chemical equation and balance it!!!
nirvana33 [79]
You can start by writing out the molecular formula of each molecule.

Aluminum (Al 3+) Phosphate (PO4 3-)

AlPO4

Nickel II (Ni 2+) sulfide (S 2-)

NiS

Aluminum Sulfide

Al2S3

Nickel Phosphate

Ni3(PO4)2

If you’re wondering, we get those charges by looking at the periodic table. The metals usually have a + charge based on their group number. The nonmetals usually - charge egual to 8 - their group number.

You then balance the ions by flipping the charges, dropping the signs, and adding them in as subscripts.

Now we can put it into an equation


AlPO4 + NiS —-> Al2S3 + Ni3(PO4)2

Balance by adding coefficients

2 AlPO4 + 3 NiS —-> Al2S3 + Ni3(PO4)2

At a certain temperature, 0.3411 0.3411 mol of N 2 N2 and 1.661 1.661 mol of H 2 H2 are placed in a 2.50 2.50 L container. N 2 (
Sveta_85 [38]

<u>Answer:</u> The equilibrium constant for the above reaction is 1.31

<u>Explanation:</u>

We are given:

Initial moles of nitrogen gas = 0.3411 moles

Initial moles of hydrogen gas = 1.661 moles

Equilibrium moles of nitrogen gas = 0.2001 moles

For the given chemical reaction:

                   N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)

<u>Initial:</u>         0.3411      1.661

<u>At eqllm:</u>     0.3411-x  1.661-3x      2x

Evaluating for 'x', we get:

\Rightarrow (0.3411-x)=0.2001\\\\\Rightarrow x=0.3411-0.2001=0.141

Volume of the container = 2.50 L

The expression of K_c for the above equation follows:

K_c=\frac{[NH_3]^2}{[N_2]\times [H_2]^3}

We are given:

[NH_3]=\frac{2\times 0.141}{2.50}=0.1128M

[N_2]=\frac{0.2001}{2.5}=0.08004M

[H_2]=\frac{1.661-(3\times 0.141)}{2.5}=0.4952M

Putting values in above expression, we get:

K_c=\frac{(0.1128)^2}{0.08004\times (0.4952)^3}\\\\K_c=1.31

Hence, the equilibrium constant for the above reaction is 1.31

What is the correct term for the breakdown of organic sediment into inorganic phosphorous? Organic sediment on lake bottoms and
alexandr1967 [171]

Answer:

Phosphorus Mineralization

Explanation:

Organisms are bound to die when they do, they undergo decomposition which breaks down complex organic matter into simpler organic matter. The simpler organic matter also undergoes other processes that result in the production of simple inorganic matter; One of such processes is Phosphorus mineralization, it is the process by which phosphorus contained in organic matter is converted to simple inorganic phosphates.

Based on the molar masses, how can you tell that an equation is balanced?
Ilya [14]
When you work with molar mass, you solve for the quantity of ''Moles'' within the substance by converting Mass. The way you can tell the equation is balanced would be by knowing whether the moles were equivalent on both sides or not. Therefore, if they are equal, it is balanced considering you have the same amount of moles on each side of the equation.
