The answer is a electron. I hope that helps
C it is C because a geno type is the genetic material that predicts what that feature will look like. A phenotype is how that genotype made you look on the outside.
Answer :
During diffusion, when the concentration of the molecules on both sides of the membrane is the same, the molecules will continue to move across the membrane in both the direction.
Answer 3 : It allows single-celled organism to reproduce, and other organism to repair damage tissues and grow.
Answer 4: The nucleus is an organelle that is surrounded by the cytoplasm, a jelly-like fluid.
Explanation :
Diffusion : It is a process where liquid moves from higher concentration to the lower concentration through permeable membrane.
When the concentration of the molecules on both sides of the membrane is same and the membrane is permeable membrane then diffusion will occur and the molecules will moves continuously across the membrane in both the direction.
Answer 3 :
Mitosis : It is a process of cell division. In this process, nucleus divides into two daughter cell and each daughter cell contains same number of chromosomes as present in parent nucleus.
The main purpose of the mitosis is to repair damaged tissues and growth.
Answer 4 :
Nucleus is a type of cell organelle. It is present in both animal and plant cells and it is the brain of the cell. It is present only in eukaryotic cell.
Nucleus is an organelle which is surrounded by the cell membrane which protects its from the other cells.
Cytoplasm is a jelly-like fluid which is present in the cell membrane which is made up of salt and water.
Answer:
Placing a powder into a beaker that contains liquid, resulting the beaker to get hotter.
Explanation:
Physical property is something that you can observe that does not affect the mixture/solution/substance, and that includes temperature
Answer:
A) 0.065 M is its molarity after a reaction time of 19.0 hour.
B) In 52 hours ![[Co(NH_3)5Br]^{2+}](https://tex.z-dn.net/?f=%5BCo%28NH_3%295Br%5D%5E%7B2%2B%7D)
will react 69% of its initial concentration.
Explanation:
![Co(NH_3)_5(H_2O)_3+[Co(NH_3)5Br]^{2+}(Purple)(aq)+H_2O(l)\rightarrow [Co(NH_3)_5(H_2O)]^{3+}(Pinkish-orange)(aq)+Br^-(aq)](https://tex.z-dn.net/?f=Co%28NH_3%29_5%28H_2O%29_3%2B%5BCo%28NH_3%295Br%5D%5E%7B2%2B%7D%28Purple%29%28aq%29%2BH_2O%28l%29%5Crightarrow%20%5BCo%28NH_3%29_5%28H_2O%29%5D%5E%7B3%2B%7D%28Pinkish-orange%29%28aq%29%2BBr%5E-%28aq%29)
The reaction is first order in :
Initial concentration of = ![[A_o]=0.100 M](https://tex.z-dn.net/?f=%5BA_o%5D%3D0.100%20M)
a) Final concentration of after 19.0 hours= ![[A]](https://tex.z-dn.net/?f=%5BA%5D)
t = 19.0 hour = 19.0 × 3600 seconds ( 1 hour = 3600 seconds)
Rate constant of the reaction = k = 
The integrated law of first order kinetic is given as:
![[A]=[A_o]\times e^{-kt}](https://tex.z-dn.net/?f=%5BA%5D%3D%5BA_o%5D%5Ctimes%20e%5E%7B-kt%7D)
![[A]=0.100 M\times e^{-6.3\times 10^{-6} s^{-1}\times 19.0\times 3600 s}](https://tex.z-dn.net/?f=%5BA%5D%3D0.100%20M%5Ctimes%20e%5E%7B-6.3%5Ctimes%2010%5E%7B-6%7D%20s%5E%7B-1%7D%5Ctimes%2019.0%5Ctimes%203600%20s%7D)
![[A]=0.065 M](https://tex.z-dn.net/?f=%5BA%5D%3D0.065%20M)
0.065 M is its molarity after a reaction time of 19.0 h.
b)
Initial concentration of = ![[A_o]=x](https://tex.z-dn.net/?f=%5BA_o%5D%3Dx)
Final concentration of after t = ![[A]=(100\%-69\%) x=31\%x=0.31x](https://tex.z-dn.net/?f=%5BA%5D%3D%28100%5C%25-69%5C%25%29%20x%3D31%5C%25x%3D0.31x)
Rate constant of the reaction = k =
The integrated law of first order kinetic is given as:
t = 185,902.06 s = 
≈ 52 hours
In 52 hours will react 69% of its initial concentration.
