True
Explanation:
In the electron dot notation, the two dots on Be represents valence electrons in the s-sublevel.
The electron dot notation is also known as lewis dot structure.
This notation shows only the chemical symbol surrounded by dots to represent the valence electrons.
The dots are arranged at the four sides of the symbol in pairs called lone pairs. The unpaired ones are the odd electrons.
For Be, the structure is 1s² 2s²
The 2s sublevel is in the outermost/valence shell and it is made up of two electrons.
It is correct to say that the two dots on Be denotes the valence electrons in the s-sublevel.

Increasing reaction temperature increased the kinetic energy in the system. In fact, the <em>measurement of</em> <em>temperature </em>indirectly relates the relative amount of kinetic energy in a system.
An increase in kinetic energy results in more rapid and forceful molecular collisions, thereby increasing the rate of molecular interactions (and in a fixed-volume system, the pressure increases as well!). Hence, the reaction can occur more quickly.
Answer:
We will not have a reaction.
Explanation:
The alcohol 2-methylhexan-2-ol its a <u>tertiary alcohol</u>. Additionally, the reaction of 
and acid medium will produce <u>chromic acid</u> 
with the following reaction:
<u>Chromic acid is a strong oxidant</u>, so an <u>oxidation-reduction</u> reaction will take place. But, in this case. we have tertiary alcohol (see figure 1). <u>Primary alcohols</u> are oxidized to aldehydes and aldehydes are oxidized to carboxylic acids. <u>Secondary alcohols</u> are oxidized to ketones and <u>tertiary alcohols </u>can not be oxidized due to the lack of hydrogens on the carbon that is bonded to the "OH" group.
<u>Therefore we will have no reaction.</u>
