The carbon atom is uniquely suited to building large molecules primarily because of its valence electron count of 4 - which means it can bound up to 4 atoms (single bonds) simultaneously. Also, it has a relatively low molecular weight and the best part is that it forms covalent bonds (stable, high energy bonds) with other, non-metallic atoms.

We observe a distant object in space and see that the spectral lines for hydrogen in the object's light appear at a shorter wave

MrMuchimi

Answer:

This tells us the radial velocity of the object and that the object is approaching or coming towards us.

Explanation:

Certain chemicals radiate with particular wavelengths or colors when their temperature is raised or when they are charged electrically. Also observable are dark strokes separating the spectrum known as absorption lines

These spectral lines of chemicals are well known as stated above and from the phenomenon of Doppler effect, spectroscopy can be used to detect the movement of a distant object by the change of the emitted frequency of the wavelength

The Doppler effect is used in calculating the radial velocity of a distant object due to the fact that an approaching object compresses its emitted signal wavelength while a receding object has a longer wavelength than normal

Use the law of conservation of mass to answer the questions. Consider a hypothetical reaction in which A and B are reactants and

shutvik [7]

Answer:

26 grams of D will be produced.

Explanation:

The reaction is given by:

A + B -----> C + D

Mass of A reacted = 21 g

Mass of B reacted = 22 g

Mass of C formed = 17 g

Mass of D formed = m =?

According to law of conservation of mass, the total mass of the reactants used is equal to the total mass of the product formed.

Then:

mass of A reacted + mass of B reacted = mass of C formed + mass of D formed

21 + 22 = 17 + m

m = 26 g
