Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allow more molecules and ions move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
Answer:
0.049 mol/L.s
Explanation:
The decomposition of hydrogen peroxide is:
![Rate = -\dfrac{\Delta [H_2O_2]}{\Delta t}= \dfrac{\Delta [H_2O_2]}{\Delta t}= \dfrac{ 2 \Delta [H_2O_2]}{\Delta t}](https://tex.z-dn.net/?f=Rate%20%3D%20-%5Cdfrac%7B%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D%3D%20%5Cdfrac%7B%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D%3D%20%5Cdfrac%7B%202%20%20%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D)
The rate of decomposition reaction = the rate of formation of 
= 0.098 mol/L.s
∴
Rate of formation of 
= 0.049 mol/L.s
Answer:
If pOH is 3.05, pH is 10.95 or
[H+]=1.122⋅10−11 mol/L
Explanation:
pH=−log(H+)Now, what is H+
if your pH is 10.95 (since pH+pOH=14, your pH=10.95).
(H+)=10 −10.95
(H+)=1.122⋅10 −11
This is your hydrogen ion concentration: [H+]=0.00000000001122 mol/L
CO2 will be the first to boil because it will be the first to warm up because it is the closest temperature to 0
A theory is like a hypothesis like an idea. Observation is to gain information like taking notes about what you see.
