1. summarize the rules for naming binary molecular compounds. 2. define a binary molecular compound. 3. describe the difference between a binary acid and an oxyacid. 4. apply using the system of rules for naming binary molecular compounds, describe how you would name the molecule n₂o₄. 5. apply write the molecular formula for each of these compounds: iodic acid, disulfur trioxide, dinitrogen monoxide, and hydrofluoric acid.

Explanation:

Question 1.

1. Name in same order as formula.

2. Drop the last syllable (or two) of last element and add -ide.                  

3. Add prefixes to each element to show how many of each.

Question 2.

A binary molecular compound is a substance composed of exactly two different elements, that cannot be simplified further by chemical means. Examples of binary compounds include H2O, H2S, and NH3.

Question 3.

The Major  difference between binary acids and oxyacids is that oxyacids contain at least one oxygen atom in the molecule and binary acids do not contain oxygen. Binary acids have hydrogen and another non-metal element in the molecule. Examples of oxyacids are H2SO4, HNO3 etc. Examples of binary acids are HCl, HBr etc.

Question 4.

Step 1 - Nitrogen Oxygen

Step 2 - Nitrogen Oxide

Step 3 - Dinitrogen Tetraoxide

Question 5.

Iodic Acid -  HIO3

Disulphur Trioxide - S2O3

Dinitrogen Monoxide - N2O

HydroFluoric Acid - HF

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

c) should be the answer.
