Answer : It takes time for the concentration to decrease to 0.100 M is, 22.4 s
Explanation :
Formula used to calculate the rate constant for zero order reaction.
The expression used is:
![\ln [A]=-kt+\ln [A_o]](https://tex.z-dn.net/?f=%5Cln%20%5BA%5D%3D-kt%2B%5Cln%20%5BA_o%5D)
where,
![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= initial concentration = 0.537 M
![[A]](https://tex.z-dn.net/?f=%5BA%5D)
= final concentration = 0.100 M
t = time = ?
k = rate constant = 0.075 M/s
Now put all the given values in the above expression, we get:
Therefore, it takes time for the concentration to decrease to 0.100 M is, 22.4 s
<span>The first ionization
energy is the energy that is obligatory in order to eliminate the first
electron from an atom(neutral) in the GAS phase
, the second ionization energy is defined as the
energy required to remove the second electron from an atom(+1 ion) in the GAS phase.
</span>the third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.)
<span> Ionization energy will normally increase for every electron that is removed and
increases from left to right in the periodic table and moving up the periods

Answer:
Sugar aka Glucose
Explanation:
Cellular respiration is reverse photosynthesis! Using that knowledge we know that plants release oxygen and glucose (sugar) which is what is needed for cellular respiration to occur!
Hope this helped! Stay safe and good luck!
Answer:
The answer to your question is Volume = 0.7 l
Explanation:
Data
Volume 1 = V1 = 0.746 l
Pressure 1 = P1 = 94.6 kPa
Volume 2 = V2 = ?
Pressure 2 = 101.33 kPa
Process
To solve this process use Boyle's law.
P1V1 = P2V2
-Solve for V2
V2 = P1V1/P2
-Substitution
V2 = (94.6 x 0.746) / 101.33
-Simplification
V2 = 70.57 / 101.33
-Result
V2 = 0.696 l ≈ 0.7 l
It has to weigh the same weight as the amount of water it displaces. eg - if it weighs a kg, it would have to displaces exactly 1 litre of water
