Answer:
Deposition
Explanation:
Deposition: The gaseous substance turns directly into a solid without undergoing the liquid phase
Just search it up on the internet:)
Answer: The final temperature of both the weight and the water at thermal equilibrium is
.
Explanation:
The given data is as follows.
mass = 7.62 g, 
Let us assume that T be the final temperature. Therefore, heat lost by water is calculated as follows.
q =
= 
Now, heat gained by lead will be calculated as follows.
q =
=
According to the given situation,
Heat lost = Heat gained
= 
T = 
Thus, we can conclude that the final temperature of both the weight and the water at thermal equilibrium is
.
Answer:
If the concentration of product D is increased, the rate of the reverse reaction would increase.
Explanation:
Chemical reaction:
A + B ⇄ C + D
In given condition the equilibrium is disturb by increasing the concentration of product.
When the concentration of product D is increased the system will proceed in backward direction in order to regain the equilibrium. Because when the product concentration is high it means reaction is not on equilibrium state the reaction will proceed backward direction to regain the equilibrium state.
According to the Le- Chatelier principle,
At equilibrium state when stress is applied to the system, the system will behave in such a way to nullify the stress.
The equilibrium can be disturb,
By changing the concentration
By changing the volume
By changing the pressure
By changing the temperature
