What is the relationship between KMT and Sea Level Rise? CER format 3-4 sentences

1 answer:

4 0

Sea level may rise as a result of the expansion of seawater and the melting of land-based ice due to a warming environment.

<h3>What is the sea level?</h3>

The sea level is the fundamental level for calculating height and depth on Earth. Since the ocean is one continuous body of water, its surface tends to seek a constant level. The sea surface is not actually level due to winds, currents, river discharges, fluctuations in gravity, and temperature.

<h3>Why is sea level important?</h3>

People are impacted by sea level changes through flooding, the inability of rivers to empty into the ocean due to the sea being too high, and the surge of seawater onto the land during storms. Our drinking water and the ability to cultivate crops could be harmed if sea water gets into farms and reservoirs.

Use the picture below to answer the question. What is true about the relationship between the wavelength and the frequency of th

KatRina [158]

The picture is not loading as it requires a sign in.
However, I can tell you how to solve this.

Answer:
<span>As the wavelength gets shorter (closer together), the frequency of the wave increases.

Explanation:
The relation between frequency and wavelength can be described by the help of velocity as follows:
velocity = frequency * wavelength
This means that:
frequency = velocity / wavelength
Noting this equation, we will find that:
The frequency and the wavelength are inversely proportional to each other. This means that as the frequency increases, the wavelength decreases and vice versa.
Now, examining the choices given, we can find that the only statement showing the inverse relation between frequency and wavelength is:
</span><span>As the wavelength gets shorter (closer together), the frequency of the wave increases.

Hope this helps :)

What is the maximum amount in moles of P2O5P2O5 that can theoretically be made from 112 gg of O2O2 and excess phosphorus

Nastasia [14]

Answer:

$n_{P_2O_5}^{max}=1.4molP_2O_5$

Explanation:

Hello!

In this case, since the reaction between phosphorous and oxygen to form diphosphorous pentoxide is:

$2P+\frac{5}{2}O_2\rightarrow P_2O_5$

Thus, since phosphorous is in excess and oxygen and diphosphorous pentoxide are in a 5/2:1 mole ratio, we can compute the maximum moles of product as shown below:

$n_{P_2O_5}^{max}=112 gO_2*\frac{1molO_2}{32.00gO_2}*\frac{1molP_2O_5}{5/2molO_2}\\\\ n_{P_2O_5}^{max}=1.4molP_2O_5$

Best regards!

Percentage yield of sodium peroxide if 5 g of sodium oxide produces 5.5 g of sodium peroxide

Rama09 [41]

<h3>Answer:</h3>

87.40 %

<h3>Explanation:</h3>

Concept being tested: Percent yield of a product

We are given;

Mass of Sodium oxide 5 g

Experimental or Actual yield of sodium peroxide IS 5.5 g

We are required to calculate the percent yield of sodium peroxide;

The equation for the reaction that forms sodium peroxide is

2Na₂O + O₂ → 2Na₂O₂

<h3>Step 1; moles of sodium oxide</h3>

Moles = mass ÷ molar mass

Molar mass of sodium oxide is 61.98 g/mol

Therefore;

Moles = 5 g ÷ 61.98 g/mol

= 0.0807 moles

<h3>Step 2: Theoretical moles of sodium peroxide produced </h3>

From the equation, 2 moles of sodium oxide produces 1 mole of sodium peroxide.

Thus, moles of sodium peroxide used is 0.0807 moles

<h3>Step 3: Theoretical mass of sodium peroxide used</h3>

Mass = Number of moles × Molar mass

Molar mass of sodium peroxide = 77.98 g/mol

Therefore;

Theoretical mass = 0.0807 moles × 77.98 g/mol

= 6.293 g

Theoretical mass of Na₂O₂ is 6.293 g

<h3>Step 4: Percent yield of Na₂O₂</h3>

We know that percent yield is given by the ratio of actual yield to theoretical yield expressed as a percentage.

$Percent yield=(\frac{Actual yield}{theoretical yield})100$

$Percent yield(Na_{2}O_{2})=(\frac{5.5g}{6.293g})100$

= 87.40 %

Therefore, the percentage yield of sodium peroxide is 87.4%

Is there unlimited space in space?

Ahat [919]

I think so since in the universe there are other universes as well so maybe the might be even more space in space it is kind of confusing but it makes sense so yes the is space in space. Hope it helped pls give brainlyest

Which of the following solutions is a good buffer system?A solution that is 0.10 M HCN and 0.10 M NaClA solution that is 0.10 M

patriot [66]

Answer:

A solution that is 0.10 M HCN and 0.10 M LiCN

Explanation:

A good buffer system contains a weak acid and its salt or a weak base and its salt.
In this case; A solution that is 0.10 M HCN and 0.10 M LiCN, would make a good buffer system.
HCN is a weak acid, while LiCN is a salt of the weak acid, that is, CN- conjugate of the acid.
