As you go down deeper, less water is able to receive the heat from the sun or other sources, so naturally they would be cooler than the water at the top

Which of these electron transitions correspond to absorption of energy and which to emission?
Elan Coil [88]

Answer:

n = 5 to n = 6 absorption

n = 9 to n = 6 emission

n = 6 to n = 4 emission

n = 6 to n = 7 absorption

Explanation:

According to the Bohr's model of the atom. An electron in an atom may absorb energy and move from a lower energy level to a higher energy level. This requires absorption of energy that is equal to the energy difference between the two levels.

Similarly, an electron may move from a higher to a lower energy level, releasing energy that is equal to the energy difference between the higher and the lower level. This is known as emission.

Hence, if the electron is moving from a lower energy level to a higher energy level, an absorption has taken place, e.g n = 5 to n = 6

When an electron moves from a higher energy level to a lower energy level, an emission has taken place e.g n = 9 to n = 6

Which of these accurately describes the reactants of a reaction?
oksian1 [2.3K]

Option (C) is the correct answer.

In the chemical reaction, reactants are the starting elements or compounds which will chemically react and will form the products. Reactants are only present on the left hand side of the reaction and products are present on the right hand side of the reaction.

Reactants present in the reaction is completely used up in the reaction to form products implies no traces of reactants will be present in the product side.

For example:

2H_{2}+O_{2}\rightarrow 2H_{2}O

Here, hydrogen and oxygen are the reactants whereas water is the product (new substance). Hydrogen reacts with oxygen and form water i.e. hydrogen and oxygen is completely used up in the reaction to form new substance i.e. water.

Hence, substances that are used up in a reaction is known as reactants of the reaction.
