Looks like you're missing an answer choice. I have this question on my practice test for AP Chemistry, the correct answer would be KCl.
mass AgCl = 2.23 - 0.80 = 1.43g AgCl
1.43g AgCl / 143g/mol AgCl = 0.01 moles AgCl
- AgCl has a mole ratio of 1:1 so:
moles Ag+ = moles Cl-, therefore Ag+ has 0.01 moles and Cl- has 0.01 moles
- MCl also has a 1:1 ration
moles Cl- = moles M+
- 0.01 moles of M+ and Cl-
0.01 Cl- = x/35.45 = 0.3545g Cl-
mass MCl = 0.74g
0.74g MCl - 0.3545g Cl- = 0.3955g M+
0.3955g M+/x =0.010 mol M+
x= 39.55g M+
K+ has a molar mass of approximately 39.10
Therefore KCl is your answer
<span>If an adult with the diagnosis of schizophrenia is admitted to the psychiatric hospital during the first few hospital days the nurse should seek out the client frequently in order to spend short periods of time together. Seeking out the client frequently to spend short periods of time together will help the nurse establish trust without increasing the person's anxiety. Seeing that the client bathes and changes clothes daily is not a priority unless the client is super and extremely dirty; this client is ungroomed, not dirty. A withdrawn client will usually not approach anyone and the client's history reveals a failure to speak.</span>
Answer:
During the inflammatory reaction and cytokine / cell diffusion, a chemical compound called nitric oxide, known as NO, is released. This chemical compound increases the permeability of the vessels, that is, the separation between the endothelial cells of the vessels to promote diffusion, inflammation and diapedesis.
Explanation:
Another factor that promotes permeability of the vessels are pro-inflammatory cytokines and chemicals released by antigen-presenting cells.
We can say they're the ISOTOPES of an element.
Isotopes of an element means the atoms of the same element has the same number of protons but different number of neutrons. They're still the same element because their number of proton is the same, which is like an ID card number, each element has a specific number of protons.
Each element has different amount of Isotopes. Some may have a lot, probably up to twenty, and some only have one stable isotope. For example, in hydrogen, there's the hydrogen atom with 0 neutrons, 1 neutron and 2 neutrons. They're the Isotopes of hydrogen.
Different isotopes of an element has a different atomic mass, as the number of neutron is different. Additionally, they also have different abundance in the environment. Maybe certain Isotopes can be found more in the earth.
Animal cells have a cell membrane and not a cell wall. They have ribosomes and lysosomes and their nucleus is enveloped by a nuclear membrane. This means that the first description;
Cell membrane present;
ribosomes present;
lysosomes present;
nuclear membrane present.
Matches ANIMAL.
Plant cells on the other hand have something called a cell wall, which are more rigid than cell membranes. Plant cells are known for their large vacuole. They also have a nuclear membrane that covers its nucleus.
The third description:
Cell wall present
Ribosomes present
Nucleus present
Large vacuole present
Matches PLANT.
Viruses do not have any membrane on its wall nor its nucleus. Basically, they have no internal structures. The fourth and last description:
Reproduces inside of a cell
Nucleus absent
RNA present
Matches VIRUS
Prokaryotes are primitive cells and they do have a cell wall but they have no defined nucleus, which means they do not have a nuclear membrane. The second description:
Cell wall present
Ribosomes present
Nuclear membrane absent
Matches PROKARYOTE
