Answer:
A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink. A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.
Explanation: hope this helps :) sorry if it's wrong :(
B. the whole point of the microscope was to see small cells and examine them
Answer:
The correct option is C.
Explanation:
Nuclear and chemical reactions are two types of reactions that one usually encounter in chemistry. These two reactions differ from each other significantly. For instance, the nuclear reactions usually involve the nucleus of the involving atoms while chemical reactions has to do with the electrons that are located outside of the nucleus of the atoms. Also, it is only chemical reaction that are influenced by factors such as temperature, pressure, catalyst, etc. Such factors does not determine the rate of nuclear reactions.
Answer:
The half life time of first order reaction is 1.3 sec
Explanation:
Given:
First order rate constant
![M^{-1} s^{-1}](https://tex.z-dn.net/?f=M%5E%7B-1%7D%20s%5E%7B-1%7D)
Initial concentration
M
From the formula of first order half life time,
![K = \frac{0.693}{t_{\frac{1}{2} } }](https://tex.z-dn.net/?f=K%20%3D%20%5Cfrac%7B0.693%7D%7Bt_%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%20%7D)
So half life time is given by,
![{t_{\frac{1}{y2} } } = \frac{0.693}{0.54}](https://tex.z-dn.net/?f=%7Bt_%7B%5Cfrac%7B1%7D%7By2%7D%20%7D%20%7D%20%3D%20%5Cfrac%7B0.693%7D%7B0.54%7D)
sec
Therefore, the half life time of first order reaction is 1.3 sec.
