8 ### Question on Gaseous Densities and BuoyancyThe density of air at Standard Temperature and Pressure (STP) is 1.285 g/L. Which of the following gases cannot be used to fill a balloon that will float in air at STP?- CH₄ (Methane)- NO (Nitric Oxide)- HF (Hydrogen Fluoride)- NH₃ (Ammonia)- Ne (Neon)#### Explanation:To answer this question, you need to understand the concept of density and buoyancy. At STP, if a gas has a density less than that of air, it will make a balloon float. Conversely, if the gas has a higher density, the balloon will not float in air.For this question, you are asked to identify the gas among the options listed that has a density greater than 1.285 g/L and hence cannot be used to fill a balloon that will float in air at STP.

Given that , Density of air at STP = 1.285 g/L At STP , Temperature (T) = 273.15 K Pressure (P) = 1…

Answered: The density of air at STP is 1.285 g/L.…

The density of air at STP is 1.285 g/L. Which of the following cannot be used to fill a balloon that will float in air at STP? O CH4 O NO HF O NH3 O Ne

Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.
