The reaction between nitrogen and hydrogen to produce ammonia is described by the equilibrium reaction 3 H 2 + N 2 − ⇀ ↽ − 2 NH
77julia77 [94]

The question correctly reads:

The reaction between nitrogen and hydrogen to produce ammonia is described as an equilibrium reaction. What substances are present in the reaction mixture when equilibrium has been obtained?

3H2 + N2 = 2NH3

N2

H2

NH4+

NH3

Answer:

N2,H2,NH3

Explanation:

Equilibrium is said to be attained when the rate of forward reaction equals the rate of reverse reaction. That is forward and reverse reactions occur at the same rate. The rate at which reactants are reformed, is the same rate at which products are formed. Hence at equilibrium both reactants and products are present in the reaction mixture. This implies that nitrogen, hydrogen and ammonia are all present in the reaction mixture at equilibrium.

An object starts from rest and exhibits the motion represented by the graph. The object’s average velocity during the 3 second t
Rufina [12.5K]

Answer:

8.4 m/s

Explanation:

Initial velocity of the object is 0 as it was at rest.

We need to find the object’s average velocity during the 3 second to 5 second.

We can see from the graph that from 3 s to 5 s, the graph is a straight line. If we take the slope we can find the average velocity during the 3 second to 5 second.

Displacement between 3 s to 5 s is :

D = 24.8 m - 8 m = 16.8 m

Time = 5 s - 3 s = 2 s

Now,

Average velocity,

v=\dfrac{\Delta y}{\Delta x}\\\\y=\dfrac{16.8\ m}{2\ m}\\\\y=8.4\ m

So, the object’s average velocity during the 3 second to 5 second is 8.4 m/s.

What is bank?Effect of drug abuse.<br>​
jeyben [28]

- Long term effects

Chronic drug use can alter a person’s brain structure and function, resulting in long-term psychological effects, such as: depression, anxiety, panic disorders, increased aggression, paranoia, hallucinations.

- Cardiovascular disease

Stimulants, such as cocaine and methamphetamines, can damage the heart and blood vessels. The long-term use of these drugs can lead to coronary artery disease, arrhythmia, and heart attack.

- Respiratory problems

Drugs that people smoke or inhale can damage the respiratory system and lead to chronic respiratory infections and diseases. Opioids slow a person’s breathing by binding to specific receptors in the central nervous system that regulate respiration. By depressing a person’s respiration, these drugs can lead to slow breathing or heavy snoring.

- Kidney damage

The kidneys filter excess minerals and waste products from the blood. Heroin, ketamine, and synthetic cannabinoids can cause kidney damage or kidney failure.

- Liver disease

Chronic drug and alcohol use can damage the liver cells, leading to inflammation, scarring, and even liver failure.

- Overdose

Taking too much of a drug or taking multiple drugs together can result in an overdose. According to the Centers for Disease Control and Prevention (CDC), drug overdose caused 67,367 deathsTrusted Source in the United States in 2018. Opioids contributed to nearly 70% of these deaths.

How to get help:

Finding the right treatment program can be a daunting task. Here are a few things to think about when seeking treatment for drug abuse, misuse, or addiction:

consider whether inpatient or outpatient services would be the best fit

find local treatment centers using this resource from the Substance Abuse and Mental Health Services Administration

note that state-run treatment centers and programs can be free of charge

look for programs that use evidence-based treatment strategies
