Answer:
The plate would only begin to slowly cool down
Explanation:
As the plate is introduced to room temperature the plate kind of stimulates oxidation in a way as in the plate is no longer in a state of continuous heat.
Answer:
0.529
Explanation:
Let's consider the reaction A → Products
Since the units of the rate constant are s⁻1, this is a first-order reaction with respect to A.
We can find the concentration of A at a certain time t (![[A]_{t}](https://tex.z-dn.net/?f=%5BA%5D_%7Bt%7D)
) using the following expression.
![[A]_{t}=[A]_{0}.e^{-k\times t}](https://tex.z-dn.net/?f=%5BA%5D_%7Bt%7D%3D%5BA%5D_%7B0%7D.e%5E%7B-k%5Ctimes%20t%7D)
where,
[A]₀: initial concentration of A
k: rate constant
![[A]_{t}=0.548M.e^{-3.6\times 10^{-4}s^{-1}\times 99.2s }](https://tex.z-dn.net/?f=%5BA%5D_%7Bt%7D%3D0.548M.e%5E%7B-3.6%5Ctimes%2010%5E%7B-4%7Ds%5E%7B-1%7D%5Ctimes%2099.2s%20%7D)
![[A]_{t}=0.529 M](https://tex.z-dn.net/?f=%5BA%5D_%7Bt%7D%3D0.529%20M)
Answer:
Change occur in heat energy.
Explanation:
Change occur in the heat energy of molecules during condensation process. The molecules of gas releases its heat energy and converted into liquid state. With this heat energy, they are active and escape from each other but when the heat energy is removed from them, the attractive forces between these gas molecules are formed which convert them into liquid state so change in heat energy occur in the condensation process.
Hot and cold water can be mixed together to make warm water is the correct statement that shows role of chemistry.
<h3>
What demonstrates the role of chemistry?</h3>
Hot and cold water can be mixed together to make warm water is the statement that demonstrates the role of chemistry in getting ready for school in the morning because it describes the features of warm water. It also shows the method of getting warm water from mixing of hot and cold water.
So we can conclude that Hot and cold water can be mixed together to make warm water is the correct statement that shows role of chemistry.
