The Sun is a yellow star that's both average in brightness and temperature and is classified as

Roman55 [17]

Answer:

Classifying stars according to their spectrum is a very powerful way to begin to understand how they work. As we said last time, the spectral sequence O, B, A, F, G, K, M is a temperature sequence, with the hottest stars being of type O (surface temperatures 30,000-40,000 K), and the coolest stars being of type M (surface temperatures around 3,000 K). Because hot stars are blue, and cool stars are red, the temperature sequence is also a color sequence. It is sometimes helpful, though, to classify objects according to two different properties. Let's say we try to classify stars according to their apparent brightness, also. We could make a plot with color on one axis, and apparent brightness on the other axis, like this:

Answer:

hydration reaction

Explanation:

The type of reaction would be hydration reaction.

Hydration reaction generally involves a chemical reaction of water with another reactant and in which the water ends up being converted to another product entirely.

A good example of hydration reaction is the reaction between alkene and water leading to the production of alcohol.

$CH_2=CH_2(g) + H_2O(g)$ ⇄ $CH_3CH_2OH(g)$

Which best explains why ionization energy tends to decrease from the top to the bottom of a group? The number of orbitals decrea

cluponka [151]

Answer:

Electrons get farther from the nucleus.

Explanation:

By going from the top to the bottom of a group, the atomic number increases. That would mean that:

The number of orbitals increases, as there are more electrons.

A higher atomic number implies an increasing number of neutrons.

As there are more electrons, they get farther from the nucleus. The farther an electron is from the nucleus, the easier it is for the electron to be removed from the atom.
