Are the elements anions or cation and what's there new name if they're anions
Anon25 [30]

Answer:

Cations are ions that are positively charged. They form when they lose an electron because they would have more protons than electrons. In your problem you have for example potassium (number three).

Iodine is a cation because it lost one electron. The ion symbol then would be:

I ⁺

So this is your clue. If it has a positive or a plus sign on top, that would make it a cation. Another clue would be if it LOST an electron, then it is a cation.

An anion, on the other hand, is negatively charged, because they gain electrons, making the electrons more than the protons. In your problem, you have Iodine as an example (number one).

Iodine gained one electron and the ion symbol would be:

I⁻

So again that is your clue for anions, they have a negative or a minus sign on top of the symbol. If they GAINED an electron, that would make them an anion.

Naming monoatomic anions is easy. They are named with the suffix -ide at the end. (Cations retain their name). For example Sulfur (number two).

Sulfur is an anion that gained two electrons with an ion symbol of:

S²⁻

So from the name <u>Sulfur</u><u> </u>the name will change into "Sulfide" and its name will now be <u>Sulfide ion. </u>

Select all that apply. Which of the following are not properties of enzymes
AlladinOne [14]
Enzymes are proteins that are biological catalysts

They reduce the activation energy required for a reaction to occur and thus speed up a reaction

Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)

They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's

They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.

They aren't used in the reaction so they're re-usable.

If it isn't one of these then it is not one of the properties of enzymes
