Why are ocean currents important to coastal regions?​

Answers

Answer:

Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region.

Explanation:

Ocean currents are important to coastal regions for a number of reasons.

What are the importance?

Distribute heat. Ocean currents distribute heat around the globe, which helps to moderate the climate in coastal regions. For example, the Gulf Stream brings warm water from the Gulf of Mexico to the coasts of Europe, which helps to keep Europe's climate warmer than it would be otherwise.

Transport nutrients. Ocean currents transport nutrients from the ocean's depths to the surface, which supports marine life. For example, the California Current brings nutrients from the deep ocean to the surface, which supports a rich marine ecosystem off the coast of California.

Diversify marine life. Ocean currents help to diversify marine life by transporting different species to different parts of the ocean. For example, the Kuroshio Current brings warm water from the western Pacific Ocean to the eastern Pacific Ocean, which has helped to diversify the marine life in this region.

Record the mass of the object based on the reading from the triple-beam balance. The mass of the object is ____ grams.

Answers

Hello!

[tex]\large\boxed{167g}[/tex]

Looking at the balance, we see that:

The middle beam reads 100g.

The top beam reads 60g.

The bottom beam reads 7g.

Add all of the numbers together to get the total mass:

100 + 60 + 7 = 167g.

The mass of the object is 167 grams.

Explanation:

A triple beam balance is a mass measuring instrument used in labs to measure the mass of a substance. It unit in which it measures is grams. It consists of three beams which are: The middle beam has  Increments of 100 grams  The front beam has  Increments from 0 grams  to 10 grams  The farther beam has  Increments of 10 grams

Given :

Readings of all the scales of three beams of the triple beam balance of an object.

To find :

The mass of object whose reading on triple beam balance is given.

Solution:

Middle beam reader at 100 grams

Front beam reader at 7 grams

Farther beam reader at 60 grams

The mass of object:

10. The molar mass of CS2 is 76.14 g/mol. How many grams of CS2 are present in 10.00 mol?

Answers

Answer: C

Explanation:

There are 761.4 grams of CS2 in 10.00 mol.

To calculate the amount of grams present in a given amount of moles, the molar mass of the substance must be used, as follows:

                                        [tex]m = MM \times mol[/tex]

In this way, just perform the following operation:

                           

                                          [tex]m = 76.14 \times 10[/tex]

                                         [tex]m = 761.4 grams[/tex]

Thus, there are 761.4 grams of CS2 in 10 mol of the substance.

In the reaction given below, 23.5 grams of iron(III) oxide (Fe2O3) are reacted with excess carbon. What is the theoretical yield of iron metal?
2 Fe2O3 + 3 C --> 4 Fe + 3 CO2

If 14.5 grams of iron are recovered when the reaction is complete, what is the percent yield?


**Both answer should be written as XX.X

Answers

Answer:

Theoretical yield = 16.76 g

Percent yield = 87%

Explanation:

Given data:

Mass of iron oxide = 23.5 g

Theoretical yield of iron = ?

Actual yield of iron = 14.5 g

Percent yield of iron = ?

Solution:

Chemical equation:

2Fe₂O₃ + 3C     →  4Fe + 3CO₂

Number of moles of iron oxide:

Number of moles = mass/molar mass

Number of moles = 23.5 g/ 159.69 g/mol

Number of moles = 0.15 mol

Now we will compare the mole of iron oxide with iron metal.

                      Fe₂O₃         :            Fe

                         2              :              4

                      0.15            :          4/2×0.15 = 0.3

Mass of iron:

Mass = number of moles × molar mass

Mass = 0.3 mol × 55.85 g/mol

Mass = 16.76 g

Percent yield:

percent yield = (actual yield / theoretical yield)× 100

Percent yield = (14.5 g / 16.76 g) × 100

Percent yield = 0.87 × 100

Percent yield = 87%

A delta is a process that forms by river deposition into an ocean or marine environment.

Sediments carried by rivers in their old stage are brought near the mouth of an ocean. As the velocity of the river reduces, sediments begins to settle out. Small river tributaries breaks out into the ocean. Delta forms at an interphase between a small and large body of water. The deposited sediments forms distinct shapes as they enter the larger body of water.
