<u>Answer:</u> The correct answer is number of valence electrons.

<u>Explanation:</u>

Elements are distributed into 7 Periods and 18 groups in periodic table.

Elements that belong to same group show similar chemical properties because they have same number of valence electrons.

Beryllium belongs to Group 2 and period 2 of the periodic table.

Magnesium belongs to Group 2 and period 3 of the periodic table.

Calcium belongs to Group 2 and period 4 of the periodic table.

Hence, the correct answer is number of valence electrons.

Draw a structural formula for the alkene you would use to prepare the alcohol shown by hydroboration/oxidation.
Nastasia [14]

Answer:

See explanation

Explanation:

The question is incomplete because the image of the alcohol is missing. However, I will try give you a general picture of the reaction known as hydroboration of alkenes.

This reaction occurs in two steps. In the first step, -BH2 and H add to the same face of the double bond (syn addition).

In the second step, alkaline hydrogen peroxide is added and the alcohol is formed.

Note that the BH2 and H adds to the two atoms of the double bond. The final product of the reaction appears as if water was added to the original alkene following an anti-Markovnikov mechanism.

Steric hindrance is known to play a major role in this reaction as good yield of the anti-Markovnikov like product is obtained with alkenes having one of the carbon atoms of the double bond significantly hindered.

Answer:

Acknowledge the source of relative weight of titanium.

Explanation:

Titanium is a chemical element which durable form of metal. Titanium is 45% lighter than steel. Titanium is made by combination of multiple elements. Titanium is very difficult to extract and this is the reason this element is considered expensive. The students examining the titanium must record the weight of titanium before exploring the characteristics and properties.
