if 5.01 moles of ti are mixed with 7.86 moles of cl2 and 2.47 moles of ticl4 are formed, what is the percent yield of this react
ipn [44]

Titanium is also utilized in the construction of portable computer housings and medical implants. Despite being the ninth most prevalent element in the crust of the Earth, titanium is relatively challenging to extract from its ores. Titanium-containing oxide minerals react with solid carbon and chlorine gas to produce titanium tetrachloride and carbrabon dioxide in the first step of the extraction process.

therefore,

5.01+7.86=12.87

12.87/2.47=19.1%

Yeild Percentage is 19.1%

Minerals are naturally occurring inorganic elements or compounds with an organized internal structure, a distinctive chemical composition, crystal shape, and physical characteristics. The yield percentage is 19.1%. Quartz, feldspar, mica, amphibole, olivine, titanium, and calcite are examples of common minerals.

Which disease is most likely to cause each effect?
ratelena [41]

Answer:

destruction of red balloons: hemolysis

shaking hands and feet: parkinson's or cerebellar syndrome

pus streaks in the throat: pharyngitis

Inability of the immune system to fight pathogens: HIV or AIDS

Explanation:

In hemolysis there is a destruction of red balloons, thus generating high levels of jaundice by metabolizing the hemoglobin of those red balloons that were destroyed, generally there are pictures of hepatomegaly or an enlarged spleen.

In Parkynson's disease, there is a degeneration of dopaminergic neuronal cells, which is why there is no synthesis of dopamine. It is for this reason that these patients take levo dopa, the term levo is because a chemical group is added to trap the blood-brain barrier.

As for pharyngitis, it is a bacterial infectious disease that can manifest itself in some cases as purulent collections, inflammation and edema in the pharynx.

And finally, as for the human immunodeficiency syndrome or HIV, it is a symptom that generates a retrovirus, which can remain latent or not, in the event that it does not remain latent and is activated by destroying LTDC4, the disease would be called AIDS. Patients suffering from this disease can manifest deep mycoses, malignant neoplasms (the most frequent is kaposi's sarcoma), opportunistic infections such as pneumonia or meningitis, etc.
