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.
I think it is D. because the sun's radiant energy gives life to the earth life forms.
If i'm not mistaken amino acids can be used in our body to fuel a process in which cell replication occurs and DNA is made. So to use amino acids as fuel you would have to make sure everything is in correct order and lines up correctly from the time it's released from the nucleus to a ribosome.
Answer:
d-The client most likely has a dual diagnosis since she has both a substance dependence and depression.
Explanation:
What is dual diagnosis?
An individual with dual diagnosis shows both a mental disorder and an alcohol or drug situation. These situations is seen in unison more often. Nearly half of people who shows a mental disorder do express substance use disorder at a point or the other. The interrelationship of the two situation can worsen both.
Why do substance use disorders and mental disorders is often seen in unison?
Thou they occur together, but it can't be said that one prompt the other, even if one started earlier as in our case study.
There are three reasons showing why they occur in unison:
•Generally, risk factors may lead to both mental disorders and substance use disorders. Such as genetics, stress, and trauma.
•Mental disorders can lead to drug use and substance use disorders. Using drugs or alcohol to find relief (self-medication). This could lead to addiction.
•Substance use and addiction can contribute to the occurrence of a mental disorder. Causes brain changes.
What are the treatments for dual diagnosis?
Individuals with dual disorder should treat both conditions. For the treatment to be operative, there is need to abstain from alcohol or drugs. Treatments may involve behavioral therapies and medicines. Also, support groups importance for emotional and social support cannot be neglected.
