Scientists use a spectroscope to receive the image of a spectra of light coming from faraway stars. Spectra is sometimes considered to be the fingerprint of the elements, with each elements having different spectra.

Explanation:

They do this by examining the spectrum of light from a star. When an ingredient is inspired, it gives off the light in distinct wavelengths, or colors.

The spectra of the Sun and stars presented bright and dark lines called Fraunhofer lines. Those were shown to be generated by elements transmitting or receiving light at specific wavelengths. Because each element emits or absorbs light only at specific wavelengths, the chemical distribution of stars can be resolved.

forsale [732]
<span>Bases and Acids are chemically opposite from each other,and there are multiple ways to distinguish how they react when dissolved in water. One accepted definition is that an acid is any chemical substance that, when it is dissolved in water, creates a solution with hydrogen ion activity greater than pure/neutral water. That is, it donates a proton to the solution. Any substance with a pH less than 7.0 is an acid, and includes substances such as vinegar and lemon juice. By comparison, a base is any chemical substance that, when it is dissolved in water, creates a solution in which has hydrogen ion activity less than pure/neutral water. That is, it accepts protons. Any substance with a pH greater than 7.0 is a base, and includes substances such as ammonia and baking soda.</span>

Which property can be used to tell gold and pyrite apart?
zubka84 [21]

Answer:

D. Malleability

Explanation:

Gold is made up of the element Au and it is a metal.

Pyrite is iron sulfide and it is a non-metal.

  • They have very similar appearance to such an extent that pyrite is widely called the fool's gold.
  • To distinguish between the two, we simply explore their metallic properties.
  • Gold is malleable. Pyrite is not. It will crumble under pressure.

statuscvo [17]

Answer:

the Law of multiple proportions

Explanation:

The law of multiple proportions states that, if two elements A and B combine to form more than one chemical compound, then the various masses of one of the elements A, which combines with a fixed mass of the element B are in simple multiple ratio.

This is demonstrated in the formation of nitrogen compounds such as NO and N2O when nitrogen combines with oxygen. This ratio is always constant.
