How to identify HBr gas?
Hydrogen bromide is a colorless or faint yellow gas with a sharp, irritating odor. When dissolved in water it becomes hydrobromic acid.

What is lighter than air but can never be lifted?
Riddle. The Answer to I Am Lighter Than Air But a Hundred People Cannot Lift Me. Riddle is Bubbles.
Which gas is lighter than oxygen?
– Therefore hydrogen is the gas lighter than air. – So, the correct option is C. Note: Methane and helium are gases lighter than air because the molecular weight of the methane is 16 and the molecular weight of the helium is 4. Air has an average molecular weight of 29.
Is HBr acid or base?
Therefore the solution will be basic, and KNO 2 is a basic salt. Although the Br − ions derive from a strong acid (HBr), the NH 4 + ion derives from a weak base (NH 3), so the solution will be acidic, and NH 4Br is an acidic salt….11.5 Strong and Weak Acids and Bases and their Salts.
| Acids | Bases |
|---|---|
| HBr | NaOH |
| HI | KOH |
| HNO 3 | RbOH |
| H 2SO 4 | CsOH |
Is HBr a acid?
Hydrobromic acid is a strong acid formed by dissolving the diatomic molecule hydrogen bromide (HBr) in water. Hydrobromic acid is one of the strongest mineral acids known.
What is the structural formula of HBr?
HBr
Hydrogen bromide/Formula
How to calculate the density of a gas?
Noting that m/V is density, ρ, the equation can be written as P (MW) = (m/V)RT = ρRT. Solving for density gives the following equation for the density of an ideal gas in terms of its MW, pressure and temperature. with commonly used U.S. units as follows:
How does temperature and pressure affect the density of gas?
• At the same temperature and pressure, the same volume of gas contains the same number of molecules. Since H 2O molecules weigh less than N 2or O 2molecules, the same volume of moist air actually weighs less than the same volume of dry air • Ideal gas law for moist air:
Which is lighter in density, air or natural gas?
Natural gas has a lower density than air. It is primarily composed of methane, which is lighter than air (source). A natural gas density calculator shows that natural gas weighs 0.712 kg/m³ (0.04457 lb/ft³) vs. 1
