Complete question:

A student is working on a lab where they are trying to identify an unknown substance. The student decides to smell the solution by taking a big breath over the test tube. They immediately start to cough and their lungs are burning.

PRECAUTION:

RESPONSE:

Answer and Explanation:

Many chemicals might be recognized by their smell. Some of them might be inoffensive, some others might cause slight damage and some others might be very harmful to the person that inhales them.

In the exposed example, the solution probably damaged the respiratory tract, causing inflammation and irritation.

There are some issues to take into account to avoid an accident by inhaling a chemical:

<u>Precaution</u>:

Study the security rules of the laboratory
Always read the label of the substance
Ask the teacher or the person in charge, about the correct procedure
Proceed in the correct way, by driving the smelly vapors with your hand toward your nose. Never breathe directly over the test tube.

In case of accidents by inhaling you should:

<u>Response:</u>

Take the affected person out of the laboratory
Look for an airy place where the affected person might breath
Call an emergency service
Explain exactly what the affected person did and the chemicals that the person inhaled.

slide 4: On the Pacific Ocean Map what do you notice about the locations of continental places around the Pacific Ocean?

Dimas [21]

The continental places around the Pacific Ocean have lot of volcanic activity.

Explanation:

The Pacific plate is an oceanic plate. It borders several continental plates. On all sides, the Pacific plate is subducting below the other plates. The subduction zones have resulted in intense geological activity along the boundaries, which are right next to the continental edges. Along the sides of the continents that are having a boundary with the Pacific plate there are lot of volcanoes and earthquakes.

The boundary between the Pacific plate and the other plates around it makes up the Ring of Fire.
The Ring of Fire stretches mostly on the edges of the continents, surrounding the Pacific Ocean, and it is the place where most of the volcanoes on Earth are located.
The formation of volcanoes has influenced the topography of the edges of the continents, and all of them are mountainous along the coastlines.
All of the volcanic activity and the subduction result in cracking of the crust and adjustment of it, resulting in release of lot of energy, or as we know it - earthquakes.
