<u>Answer:</u> The below calculations proves that the rate of diffusion of 
is 0.4 % faster than the rate of diffusion of 
<u>Explanation:</u>
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 the equation:
We are given:
Molar mass of 
Molar mass of 
By taking their ratio, we get:
From the above relation, it is clear that rate of effusion of is faster than
Difference in the rate of both the gases, 
To calculate the percentage increase in the rate, we use the equation:
Putting values in above equation, we get:
The above calculations proves that the rate of diffusion of is 0.4 % faster than the rate of diffusion of
Circulate and move within a liquid or gas.
Answer:
Difference in temperature
Explanation:
Temperature is the degree of hotness or coldness of a body. The difference in temperature between two bodies enables heat transfer from the hotter body to the colder one. If two bodies are at the same temperature, heat transfer will not occur between them. This why in the vicinity of hot water, a cold water becomes warmer.
Answer:
The Cl⁻ and K⁺ are spectator ions.
Explanation:
Balanced Chemical equation:
BaCl₂(aq) + K₂CrO₄(aq) → BaCrO₄(s) + 2KCl (aq)
Ionic equation:
Ba²⁺(aq) + 2Cl⁻(aq) + 2K⁺(aq) + CrO₄²⁻(aq) → BaCrO₄(s) + 2k⁺(aq) + 2Cl⁻ (aq)
Net ionic equation:
Ba²⁺(aq) + CrO₄²⁻(aq) → BaCrO₄(s)
The Cl⁻ and K⁺ are spectator ions that's why these are not written in net ionic equation. The BaCrO₄ can not be splitted into ions because it is present in solid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
