pls give me brainliest lol :)
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.
Volume of 3M solution: x
Moles in 3M solution: 3x
C = n/V
1,8 = 3x/0,05dm³
0,09 = 3x
x = 0,03dm³
A student need 0,03dm³ 3M HCl and 0,02dm³ of water.
Answer:
5.71 x 1021 (C)
Explanation:
Because if the numbers are over 5 then u round to the next number. So since 6 is bigger than 5 that means is gonna round up so it will be 7 and so. I hope that helps a bit
