Someone pls help me I will make you brain

Rigor mortis is the stiffening of the body after death. After death, the body begins to get cold. From about two to six hours after death, the muscles start to stiffen, probably because the actin and myosin filaments of the muscle slide into each other. The rigor mortis starts at the eyelids, jaw and neck and then slowly spreads to all parts of the body within six hours.

Contrary to popular belief, rigor mortis will occur more quickly in high ambient temperatures than in cold conditions. This is because the underlying chemical reaction occurs faster at higher temperatures.

Answer:

Temperature and pressure are the two factors which are responsible for change in state of matter.

Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.

Answer:

Fluroine

Explanation:

Answer:

Fluorine

Explanation:

Nitrogen atomic radius: 155 pm

Oxygen atomic radius: 152 pm

1. The equation representing the equation is ~

[tex] \mathrm{Na + Cl\rightarrow NaCl}[/tex]

The given reaction is a redox reaction because there's a transfer of electron from Sodium (Na) to chlorine (Cl)

where sodium is oxidized (due to loss of electron) and chlorine get reduced (due to gain of electron).

2. Sodium is a highly reactive element which belongs to the 1st group of periodic table, hence it can catch fire if it is kept free in atmosphere. so in order to prevent that it is stored in kerosene oil, which doesn't let Sodium come in contact with air .

Many nitrogen and carbon atoms can be found in the structure of a heterocyclic molecule called xanthine, which is present in many biological systems.

The development of a sigma bond between these atoms is an essential component of its binding. A special example is the sigma bond between the nitrogen atom and the neighboring carbon atom. In the context of this sigma bond, the hybridization state of nitrogen can be either [tex]\rm sp^2[/tex]or [tex]\rm sp^3[/tex], and the hybridization state of carbon can be [tex]\rm sp^3[/tex]. A sigma bond is formed when the hybrid orbitals of carbon and nitrogen, which are each [tex]\rm sp^2[/tex] hybridized and [tex]\rm sp^3[/tex] hybridized, overlap. A strong covalent bond can develop when the [tex]\rm sp^2[/tex] hybrid orbitals of nitrogen and carbon line up. This allows electron sharing.
