Which of the notations below is another way to write the name of the following nuclide?A.iodine-53

B.iodide-53

C.iodide-127

D.iodine-127

Answers

Answer: D.iodine-127:

Explanation:

1) As per the definition of nuclide, it is the atomic spieces (the atom) characterized by the nucleons (protons and neutros).

2) To notation for a nuclide is the name of the atom followed by a hypen (without blank spaces) and the mass number.

3) The mass number is the sum of protons and neutrons.

4) From that, you can tell this about the four choices given:

A.iodine-53: is not correct because that would mean that the mass number is 53, which cannot be right as the atomic number of iodine is 53 meaning that it has 53 protons, and so that notation is not including the neutrons.

B.iodide-53: is not correct because the name of the atom is iodine, not iodide (also the mass number cannot be for the same reason explained above)

The name iodide is reserved for the ions from iodine not for the atom.

C.iodide-127: incorrect due to the name iodide, for the same reason explained above.

D.iodine-127: this is correct choice. It is the name of the isotope of the iodine with mass number 127, which means that the atom has 53 protons and 74 neutrons (53 is the atomic number and 74 is calculated from 127 - 53)

Effects of warm tropical waters meeting with cool air.

Answers

The effect of warm tropical waters meeting with cool air is hurricane.

What is a hurricane?

A hurricane is formed when warm tropical water meet with air that is cool and humid. This creates a zone of pressure over the warm water causing the air to rotate.

Hence, the effect of warm tropical waters meeting with cool air is hurricane.

Why are cells small?

Answers

Because if a cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
They are also small so they can maximize the ratio of surface area to volume. Smaller cells have a higher ratio which allows more molecules and ions move across the cell membrane per unit of cytoplasmic volume.

basically cells are small because they need to be able to get the nutrients in and waste out quickly.

The pH is a solution remains constant in the presence of a buffer if acid or base is added beyond the buffer capacity. True or false.

Answers

The strong acid and strong base has high rate constant of dissociation. Weak acid and base are the one whose rate constant for the dissociation is low, they do not dissociate readily in water. Therefore, the given statement is false.

What are acid and base?

Acid is a solution which releases H⁺ hydrogen ion when dissolved in water. Base are the solution which releases hydroxide ion OH⁻ ion when dissolved in water. pH is measurement of hydronium ion.

A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH. The statement is false. When you add an acid or base in amounts greater than the buffer capacity you no longer have the buffer to influence solution pH.

Therefore, the given statement is false.

What is the chemical name of the compound Cu2CO3?

Answers

Answer:

Copper (I) carbonate or cuprous carbonate.

Explanation:

Hello,

In this case, by considering the given formula, we identify the copper's oxidation state as +1 since the carbonate anion is -2 and copper's subscript is 2, therefore +1 is its oxidation state. On the other hand, carbon's oxidation state in CO₃⁻² is +4, that is why according to the IUPAC rules, its name is carbonate. Thus, one sums up that the chemical name of the given compound is copper (I) carbonate or cuprous carbonate.

Best regards.
