What kind of bonding would exist between<br> sulfur and hydrogen?
Alexandra [31]

Answer:

nonpolar covalent

Explanation:

Comparing their electronegativities will help determine the type of bond. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The difference in electronegativity (ΔEN)  is used to determine bond type. Hydrogen has an electronegativity of 2.20 and sulfur has 2.58. The difference is 0.38,so the electrons are shared in a nonpolar covalent bond.

Using the Periodic Table, predict which elements will have similar chemical properties or reactivity
tekilochka [14]

Answer:

Elements in the same vertical column on the periodic table will have similar chemical properties and behave similarly in chemical reactions. These vertical columns can also be called groups/families.

erastovalidia [21]
I found a similar question online which will help me answer your incomplete question. To make it easier, show all the elements of the compound given. It is shown in the second picture attached.

a.) The formula for unsaturation number is shown in the 3rd picture attached. Following this, 
n = 8
m = 2(8) + 2 + 0 + 0 - 0 = 18
Thus,
x = Unsaturation number = (18 - 8)/2 = 5
<em>The unsaturation number is 5.</em>

b.) The molar mass of C is 12.01 g/mol; H is 1 g/mol; O is 16 g/mol. So, the molecular weight is:
Molecular weight = 12.01(8) + 8(1) + 2(16) = 136.08 g/mol
<em>The molecular weight of the ester is 136.08 g/mol.</em>

weeeeeb [17]

Answer:

An unsaturated solution can dissolve more solute at the given temperature. If you add more solute until the solution will dissolve no more at that temperature, it is saturated solution.

Explanation:

In unsaturated solution, there is capacity of solution to dissolve more solute inside the solution. In saturated solution, there is no capacity of a solution to dissolve any further solute at a given temperature. This capacity is increased by heating the solution so more solute will be dissolved. This is called supersaturated solution.
