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!!!

Which element has a 4s sublevel with 2 electrons for its outermost electrons.
Papessa [141]

Answer:

Calcium

Explanation:

Hi!

So, the best way to solve this is with a period table with all of the sublevels labeled. (check below)

So the s sublevel starts at 1s which is Hydrogen. If you go down 4 rows, or periods, you get to sublevels 4s. As you should know, as you go across groups/columns, the valence electrons get higher. So the element that you are looking for has 2 valence electrons. So, the element you are looking for should be 4 down and 1 right of Hydrogen which is: Calcium

I hope I helped and have a wonderful evening!

Determine the volume (mL) of 15.0 M sulfuric acid needed to react with 45.0 g of
myrzilka [38]

Answer:

167 mL.

Explanation:

We'll begin by calculating the number of moles in 45 g of aluminum (Al). This can be obtained as follow:

Mass of Al = 45 g

Molar mass of Al = 27 g/mol

Mole of Al =?

Mole = mass /Molar mass

Mole of Al = 45/27

Mole of Al = 1.67 moles

Next, the balanced equation for the reaction. This is given below:

2Al + 3H2SO4 → Al2(SO4)3 + 3H2

From the balanced equation above,

2 moles of Al reacted with 3 moles of H2SO4.

Next, we shall determine the number of mole of H2SO4 needed to react with 45 g (i.e 1.67 moles) of Al. This can be obtained as:

From the balanced equation above,

2 moles of Al reacted with 3 moles of H2SO4.

Therefore, 1.67 moles of Al will react with = (1.67 × 3)/2 = 2.505 moles of H2SO4.

Thus 2.505 moles of H2SO4 is needed for the reaction.

Next, we shall determine the volume of H2SO4 needed for the reaction. This can be obtained as follow:

Molarity of H2SO4 = 15.0 M

Mole of H2SO4 = 2.505 moles

Volume =?

Molarity = mole /Volume

15 = 2.505 / volume

Cross multiply

15 × volume = 2.505

Divide both side by 15

Volume = 2.505/15

Volume = 0.167 L

Finally, we shall convert 0.167 L to mL. This can be obtained as follow:

1 L = 1000 mL

Therefore,

0.167 L = 0.167 L × 1000 mL / 1 L

0.167 L = 167 mL

Thus, 0.167 L is equivalent to 167 mL.

Therefore, 167 mL H2SO4 is needed for the reaction.
