Which is an example of a plasma that occurs in nature?

koban [17]

The answer is: the radiant sun.

There are five fundamental states of matter (gas, liquid, solid, plasma and Bose–Einstein condensate).

Plasma is a an ionised gas with highly electrical conductivity.

It is an electrically neutral with positive and negative particles.

Plasma may be the most abundant form of matter in the universe.

Plasma was first described by chemist Irving Langmuir.

Plasma can be artificially made by heating a neutral gas to a strong electromagnetic field.

All the following ions have the same charge except Group of answer choices oxide. monohydrogen phosphate. peroxide. permanganate

Triss [41]

All the given species have the same charge except peroxide.

<h3>Charges on ions</h3>

The charge on monohydrogen phosphate is negative because of its formula, $[HPO4]^{2-}$ .

The charge on permanganate is negative. The formula is $MnO^-$

The charge of oxide ( $O^{2-}$ ) is negative.

The charge on peroxide is ( R−O−O−R) is neutral.

The charge on oxalate, $C2O4^{2-}$ , is negative.

Thus, only peroxide is unique.

What is the wavelength in nm of a light whose first order bright band forms a

miskamm [114]

Answer:

714 nm

Explanation:

Using the equation: nλ=d<em>sin</em>θ

where

n= order of maximum

λ= wavelength

d= distance between lines on diffraction grating

θ= angle

n is 1 because the problem states the light forms 1st order bright band

λ is unknown

d= $\frac{1}{700,000}$ or 0.0000014 (meters)

sin(30)= 0.5

(1)λ=(0.0000014)(0.5)

=0.000000714m or 714 nm
