Why would heating up the human body be a bad choice for causing a chemical reaction?
Furkat [3]

Answer:

Explained below

Explanation:

The human body has a normal core temperature of around 37°C to 38°C.

Now, if it is heated up to say 39° to 40°C, fatigue will start to set in and the brain begins to tell the muscles to slow down.

If it's now heated to higher temperatures above above 41°C, the body will begin to experience heat exhaustion and therefore will start to shut down.

Due to this process, the body can't even sweat at that stage because blood flow to the skin will stops thereby making the body feel cold and clammy. Thus, chemical processes/reaction in the body will begin to be affected and the cells inside the body will start to deteriorate and thus there is now a huge risk of having multiple organ failure.

Vika [28.1K]

Answer:

Organic compounds: C₃H₆, and C₂H₂.

Inorganic compounds: NaS, SO₂, and HI.

Explanation:

Organic compounds are the molecules that have a carbon backbone with hydrogen atoms in its structure.

While, inorganic molecules are composed of other elements. They can contain hydrogen or carbon, but if they have both, they are organic.

<em>So:</em>

<em>Organic compounds are C₃H₆, and C₂H₂.</em>

<em>Inorganic compounds are NaS, SO₂, and HI.</em>
