HERE IS UR ANSWER...

The data which is accurate means it can't be changed further is called accurate data.while,

The data which is changed again and again is called reproducible data.

For the following reaction, identify the element that was oxidized, the element that was reduced, and the reducing agent. Give a

Galina-37 [17]

The element oxidized is the element in which the charge becomes more positive after the reaction, hence the reducing agent. The element that is reduced is the element or compound in which the charge becomes more negative after the reaction. Sn becomes +4 from +2. Hence Sn is the reduced element while Pb becomes +2 from +4 hence Pb is the element oxidized and PbCl4 is the reducing agent.

Which list places the layers of the sun in the correct order from innermost to outermost? Corona, photosphere, chromosphere Phot

Savatey [412]

Answer:

Layers of sun from inner to outermost layer-

Core<Radiative Zone<Convection Zone<Photosphere<Chromosphere<Transition Zone<Corona

Explanation:

The Sun is comprised of 7 layers, of which 3 forms the inner layers and 4 forms the outer layers.

The inner layers are namely-

Core- It is the innermost layer of the sun where the energy is produced by nuclear fusion process and the temperature is significantly high, about millions of degree celsius. Here, the hydrogens are combined in order to form helium .

Radiative zone- This is the zone through which the energy is radiated by the photon from the core outward in the form of electromagnetic radiation that usually takes more than about 170,000 years to radiate.

Convection zone- This layer starts from the interior of about 200,000 kilometers extending up to the visible surface of the sun. The temperature in this zone is extremely high but comparatively less than the core. The energy emitted from the core is then radiated through this zone. Here, the convection cells are generated due to the continuous heating and cooling of heated materials.

The outer layers of sun are as follows-

Photosphere- This layer is considered as the solar surface which is mostly concealed by the presence of granulations, that are initiated by the bubbles of gases formed in the convection zone and also presence of sunspots that are formed due to the stronger magnetic field. The temperature ranges here from 4000° to 6500°K.

Chromosphere- Here, the temperature rises extensively as one goes away from the sun and the temperature in this layer ranges from 4000° to a maximum of 8000°K.

Transition region- It is a thin layer which is about 60 miles only where the temperature highly increases from about 8000° to 500,000°K. The reason behind this increase in temperature is yet to be discovered.

Corona- It is the outermost layer where the temperature range is from 500,000° K to 1,000,000° K. This layer is difficult to be seen with the naked eye but can be seen using a coronagraph telescope during the time of solar eclipse.
