(b)
Interpretation:
The chemical formula of the ionic compound cupric sulfate needs to be determined.
Concept Introduction:
When the number of electrons increases or decreases from the atomic number, ions are formed. Cation is a positively charged ion formed by losing electron/s and anion is a negatively charged ion formed by gaining electron/s. While writing name of the ionic compounds, the name of cation is always written first followed by the name of the anion. In order to form an ionic compound, the cation and anion combine in such a way that the total charge is zero.
(c)
Interpretation:
The chemical formula of the ionic compound potassium chloride needs to be determined.

- At first, it seemed like the poisoned Russian agent might have ingested thallium in the form of thallium(I) sulfate, a rodenticide (rat poison), not allowed in the US and Western countries but still used in other countries. Thallium leads to hair loss. It also replaces potassium in important enzymes in the brain, muscles and skin. It takes 8.0 x 102 mg of thallium ion to kill an average adult. It took a bit of investigating to figure out that the agent was actually poisoned by polonium, a radioactive element, harmful only if it goes into the body. The radioactivity emitted by polonium, alpha particles, can be stopped by skin; but, if ingested, it gets into the blood stream, travels to organs and does lots of damage. The maximum safe body amount of polonium is 7 pg (picograms!) The agent was apparently poisoned with about 10 micrograms. To provide the minimum amount of thallium to kill the average adult, how many mL of 0.45 M solution of thallium(I) sulfate needs to be ingested?…arrow_forwardWhat are the following?

- Consider Molecule X, which is found in all living cells. This single-strand nucleic acid folds into a compact shape and forms a large complex with about 80 proteins. This complex is responsible for synthesizing new proteins in a living cell. What is the name of X? Your answer should be one word, or a short two- or three-word phrase. Spelling counts.
