Answer: Odor of ammonia would we detect first on the other side of the room.
Explanation:
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:
Thus the odor of ammonia would we detect first on the other side of the room as the rate of effusion of ammonia would be faster as it has low molecular weight as compared to hydrogen sulphide.
Answer:
Write the experimental procedure like a step-by-step recipe for your science experiment. A good procedure is so detailed and complete that it lets someone else duplicate your experiment exactly. Often it includes a sketch of how to set up the experiment. The directions may be numbered to be sure they are done in the correct order.
Explanation:
Answer:
An Aqueous solution is used to reference any solution where water acts as the solvent. A lot of substances can dissolve in water including acids and bases and when they do this they become aqueous solutions.
Aqueous solutions are denoted by the symbol (aq) in solutions as shown in this reaction below where Sodium Chloride is dissolved in water;
NaCl(s) → Na+(aq) + Cl-(aq)
Aqueous solutions are capable of conducting electricity if electrolytes are the ones dissolved in the water.
There are however some substances that cannot form aqueous solutions because they cannot dissolve well in water for example, organic substances like oils.
