A rock is definitely more dense. If you were to put a cloud in water it would float/stay above it and a rock would sink to the bottom
The U-235 fission will produce krypton-92 and barium-141. And this process will also release huge amount energy. And U-235 also go through α decay model.
the answer to you question is Argon
Answer False
Explanation: Friction makes it stop at some point. For it to have an unlimited speed goes against beset is first law that states an object in motion with stay in motion unless acted upon by an external force, your force will be the friction of the wheels on the roller coaster
Answer:
B: increase.
Explanation:
When we are considering two gases A and B in a container at room temperature .
We have to find the change on rate of reaction when the number of molecules of gases A is doubled
Let [A]=a and [B]=b
A+B product
Rate of reaction
We know that concentration is increases with increase in number of moles
When the number of molecules of gases A is doubled then concentration of gases A increases.
Therefore ,[A]=2a
Rate of reaction
Hence, the rate of reaction is 2 times the initial rate of reaction.Therefore, the rate of reaction will increase when the number of molecules of gases A is doubled.
Answer: B: increase.
