Answer:

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.

How would more secondary consumers affect the biomass of the higher trophic levels?
wel

Answer:

<u>would increase, population, and chances of getting more food for survival. </u>

Explanation:

By the increase in secondary consumers, that would give more food and energy and the ease of finding food for the tertiary consumers, which will give more energy for activities and therefore sexual activity can no longer be lacking the energy barrier, and due to that the population of tertiary consumers increases, eventually leading to the same effect and increase in Quaternary consumers.

Chrysanthemums are short-day plants that normally flower in late fall. Suppose you were a chrysanthemum grower and you would lik
Whitepunk [10]

Answer:

Option D

Explanation:

Options for the question

A)import seeds produced in the southern hemisphere.

B)plant the flowers out-of doors in november.

C)keep the plants in a warm growing environment.

D)expose the plants to an hour of light in the middle of each night until the end of april.

Solution

Since Chrysanthemum is a short-day plant, its flower mainly develop during night and hence they require long nights of 11 to 12 hours. Blackout system is sometimes used to induce flowering.Flowering can be delayed by regulating both light and temperature. this is done by exposing plants for a short period of time to light (can be artificial) and to some source of heat that produces 85° F or higher temperature.  

Thus if flowers are required in month of may, flowering can be delayed by exposing Chrysanthemums plant to light and heat source during night time

Option D is correct

Why do you think people like Ben Saunders explore extreme environments? Do you think you’d like to explore an extreme environmen
adell [148]

One major reason for exploring extreme environments is to find new resources. An example of a resource is the search for a new antibiotic. Extreme environments have rare species endemic to the regions which can offer different insights from the normative environment we are used to.

No, I would not. This is because the risk of death is higher in an extreme environment. Example of these risks are deadly diseases or harsh climate. The body may be unable to adjust to the extreme environment hence may be unable to restore homoeostasis;  such as in restoring body heat in extremely cold environments hence leading to hypothermia.
