Answer:
B- Sodium loses an electron.
D- Fluorine gains an electron.
Sodium is oxidized.
Explanation:
The reaction equation is given as:
Na + F → NaF
In this reaction, Na is the reducing agent. It loses an electron and then becomes oxidized. By so doing, Na becomes isoelectronic with Neon.
Fluorine gains the electron and then becomes reduced. This makes fluorine also isoelectronic with Neon.
This separation of charges on the two species leads to an electrostatic attraction which forms the ionic bonds.
D. Wind will always move from areas of high pressure to low pressure. It's the reason we have weather, or one of them. Temperature is another factor.
B. That is the definition of the greenhouse effect.
The reason why the reaction written on the picture can be classified as a synthesis reaction is :
the reaction shows one compound that formed from two compounds

Answer:
<u><em>The correct answer is:</em></u>
<h3><u><em>
Option D: Evapotranspiration </em></u></h3>
<u><em>Water is removed both from the plants and the soil. Evapotranspiration is a process by which the water is removed from plants and ground and is added back into the atmosphere. From ground, water is removed in the form of evaporation from the soil. And from plants the water is removed by transpiration. Hence the term Evapotranspiration.</em></u>
Answer:
Oxidation: the loss of electrons
Reduction: the gain of electrons
Oxidation number: the charge based on the number of electrons assigned to an atom as compared to the neutral atom
Explanation:
The oxidation number of a neutral atom is zero. When the atom is oxidized, it loses electrons (which have a negative charge), so the oxidation number goes up. When the atom is reduced, it gains electron (it gains negative charge), so the oxidation number goes down.
