Which of the following compounds would have a linear molecular geometry? 1. N2 2. H2S 3. CO2 a. 1 and 3 only b.1 and 2 only c.2
and 3 only d.1,2 and 3 neither 1, 2,or 3
1 answer:
Answer: 1 and 3 only
Explanation:
The structures of N2 and CO2 show both to be linear compounds from the images attached. In molecular nitrogen, the two nitrogen atoms are sp hybridized just as the two carbon atoms in CO2 are sp hybridized. sp hybridization is associated with linear shape because it leads to a bond angle of 180°. Hence the answer.

Considering the definition of molarity, the molar concentration is 0.294 .
Molarity reflects the concentration of a solution indicating the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
Molarity is expressed in units .
In this case, you know:
- amount of moles of solute= 0.250 moles
- volume= 0.850 L
Replacing in the definition of molarity:
Solving:
molarity= 0.294
Finally, the molar concentration is 0.294 .
