Explain the relationship between the following terms: eutrophication, nutrients, dissolved oxygen leads, and algae.

makvit [3.9K]

Answer:

Eutrophication is the enrichment of a body of water with excessive nutrients (nitrogen and phosphorus), which causes algal growth and subsequent decline of dissolved oxygen after decomposition.

Consider this chemical reaction, where moving from left to right represents moving forward in time. A five panel comic strip. In

yulyashka [42]

Answer:

The reaction reaches equilibrium at the fourth panel.

Explanation:

Chemical Equilibrium is achieved when the overall properties the system seem to be constant, that is, stop changing.

Although, for chemical equilibrium, the right term for this equilibrium is dynamic equilibrium; the rate of forward reaction balances the rate of backward reaction, but concentrations can keep changing.

The point where equilibrium is achieved is when exactly when we reach the panel where the spheres that make up this panel is the same as the next panel and the next, that is, the specific colour and number of spheres start to become unchanged.

And from the description given in the question,

- In the first panel, there are ten large red spheres.

- In the second panel, there are 8 large red spheres and two small blue spheres.

- In the third panel, there are six large red spheres and four small blue spheres.

- In the fourth panel, there are four large red spheres and six small blue spheres.

- In the fifth panel, there are four large red spheres and six small blue spheres.

It is evident that the make-up of the spheres have become the same as at the fourth and fifth panel. This means that the first point where this final configuration of spheres first appeared is the fourth panel.

Hence, equilibrium is first reached at the fourth panel.

when aqueous solutions of sodium hydroxide and iron (II) chloride react, which substance will precipitate? 2NaOH + FeCl2 = 2NaCl

nataly862011 [7]

Answer:

Fe(OH)2

Explanation:

Iron hydroxides are chemical compounds that appear as precipitates after alkalizing solutions containing iron salts, both in their valence or degree of oxidation (III) and (II).

Hydroxide, in both cases, is a gelatinous colloid of difficult filtration that can be considered a hydrated oxide, iron (II) hydroxide is whitish in color and requires more alkalinization, above 7.

The anion O3− does not obey the octet rule. Draw its Lewis structure and state the type of octet-rule exception. Indicate the va

Tju [1.3M]

One of the oxygen atoms in the anion O3− is hypervalent and the formal charge on this oxygen atom is -1.

Ozone is a triatomic molecule. The anion formed from ozone is called the ozonide anion. This anion is also triatomic. The resonance structures of the ozonide anion are shown in the image attached to this answer.

We can see that one of the oxygen atoms in the ozonide ion is hypervalent because it contains ten instead of eight electrons. This hypervalent oxygen atom has a formal charge of -1 while the two other oxygen atoms has a formal charge of zero.

If Brian and his scooter had a mass of 50 kg, how much force would it take for him to accelerate at 0.8 m/s2

OleMash [197]

Answer:

<h2>The answer is 40 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

<h3>force = mass × acceleration</h3>

From the question

mass = 50 kg

acceleration = 0.8 m/s²

We have

Force = 50 × 0.8

We have the final answer as

Hope this helps you
