Answer:

Yes it is a Heterogenous mix because we know a piece of notebook paper comes from a tree and we know a tree is a amplafier for fire which is why it is used as a element and a compound so it is a mix

Ionic compounds are formed from ionic bonds, whereby an electron is transferred from the metal cation to the nonmetal anion. Ion

Karolina [17]

Answer:

NaI

Explanation:

In I₂, HI and IBr, both atoms are nonmetals and they form covalent bonds in which electrons are shared.

In NaI, Na is a metal and I a nonmetal, so they form an ionic bond, where Na loses an electron to form Na⁺ and I gains an electron to form I⁻. Anions and cations are attracted to each other through electrostatic forces.

Since ionic bonds are stronger than covalent bonds, more energy is required to break them in the melting process, thus having higher melting points.

All in all, NaI is the one with the highest melting point.

The chart shows how cliamate change and rising ocean temperature might affect the types of hurricanes we see this century we see

navik [9.2K]

Answer:

Check Explanation

Explanation:

The chart to be used to answer the question is currently missing. After obtaining online, I have attached it to this solution of this question.

From the graph, the prediction shows a negative percent change in the number of category 1 and category 2 & 3 hurricanes (greater than -25% change) and category 4 & 5 hurricanes get a positive percent change of more than +75% change)

Now, taking the statements, one at a time.

A. Which type of hurricane is expected to strike more frequently this century?

From the chart, only category 4 & 5 hurricanes are predicted to have a positive percent change in number, hence, they are the ones expected to strike more frequently in this century.

B) How are hurricanes formed in the atmosphere?

This information cannot be read off from the graph. So, the answer provided isn't from this chart of prediction.

Hurricanes are formed when warm, moist air from the ocean surface begins to rise rapidly, and they encounter cooler air that forces the warm water vapor to condense& form storm clouds with drops of rain.

C) In general, will hurricanes likely become stronger or weaker this century?

The less powerful hurricanes are predicted to have more than 25% negative percent change in number.

But the most powerful categories of hurricanes are predicted to have more than 75% positive percent change in number.

Although, the true figures aren't clear, but more hurricanes that happen are bound to be classified as category 4 & 5 hurricanes. It can be perceived that hurricanes are getting stronger in this century.

D) Which areas are at the highest risk of hurricanes?

This information cannot be read off from this chart. It isn't provided.

E) Which types of hurricanes are expected to drop in frequency by more than 25% this century?

From the chart, category 1 and category 2 & 3 hurricanes are predicted to drop in frequency by more than 25% this century.

F) How many category 4 and 5 hurricanes can we expect this century?

From the chart, we're predicted to have more than 75% positive percent increase in the number of category 4 & 5 hurricanes.

The number of category 4 and 5 hurricanes we should expect this century will be more than 75% higher than the previous century.

Hope this Helps!!!
