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.

A map here shows the motion of a tectonic plate off the coast of the western united states. Which evidence supports the theory o
notsponge [240]

Answer:

Fossils, the shape of continents, the mid-ocean ridge system, sea floor sediment deposits, and the magnetism of rocks.

Explanation:

Fossils, the continent's shape, the mid-ocean ridge system, sea floor sediment deposits, and the magnetism of rocks on the sea floor are the evidences that support the theory of plate tectonics in the area. Fossils provides information to us when and where plants and animals once existed. Due to diverging plates, some life became isolated, and evolved into new species. Continental ‘fit’ through coastline matching. Some division of continents look as though they should fit together, e.g. South America and Africa.

Why does iron have no oxidation state corresponds to loss of all it's valence electrons?
olganol [36]

Answer:

When an element loses an electron, its oxidation number increases.

Explanation:

The oxidation number of an element indicates the hypothetical charge of an atom in a compound. It is hypothetical because, in the context of a compound, the elements may not necessarily be ionic. When the number of electrons associated with an atom changes, its oxidation number also changes. When an element loses an electron, its oxidation number increases.
