There are 3 experiments which helps to under water evaporation system.

  • Both the temperature of the air surrounding the water and the rate of evaporation increased.
  • In the second experiment, we observed an increase in air flow around the water, and this time, the rate of evaporation increased as well.
  • In the third and final experiment, we observed an increase in the amount of light in the room, and this time, the rate of evaporation increased as well.
  • Because the kinetic energy of a substance can be measured by its temperature, increasing in the temperature or kinetic energy of the air around water will also increase the kinetic energy of the water, which will increase the rate of evaporation.
  • It's crucial to have good air flow since it drives water droplets in the air away from you, reducing the amount of humidity in the region. Because there will then be space for the evaporated air or space for the evaporated water to flow into the air, it will then be simpler for the water to really evaporate.
  • Water in the presence of sunlight is given extra energy, which increases evaporation.

A. Acid rainfall will cause a decrease in oceanic surface temperatures.
laiz [17]

Answer:

Increased atmospheric carbon dioxide will cause increased ocean surface temperatures.

Explanation:

Greenhouse gases of which CO2 is a typical example are known to cause a gradual and steady increase in the surface temperature of the earth by trapping infrared rays close to the surface of the earth.

As the surface temperature of the earth rises, the surface temperature of the oceans rises also leading to the tendency towards hurricanes.

Hurricanes are violent storms which are known to form near the equator over warm ocean waters.

Hence, increased atmospheric carbon dioxide will cause increased ocean surface temperature which in turn increases the chances of the occurrence of hurricanes.

Question 2 (2 points)
poizon [28]

Answer:

m_w=439.2g

Explanation:

Hello!

In this case, since the by-mass percent of a solution is a measure of the mass of the solute over the mass of the solution:

\%m/m=\frac{m_{solute}}{m_{solution}} *100\%

As we know the mass of the solution and the by-mass percent, we can compute the mass of glucose in the 480 g of solution:

m_{solute}=\frac{\%m/m*m_{solution}}{100\%}

Thus, by plugging in the data, we obtain:

m_{solute}=\frac{8.5\%*480g}{100\%}=40.8g

Finally, since the solution is made up of glucose and water, we compute the mass of water as follows:

m_w=m_{sol}-m_{solute}=480g-40.8g\\\\m_w=439.2g

Best regards!

The element lead (pb) consists of four naturally occurring isotopes with atomic masses 203.97302,205.97444,206.97587, n 207.9766
Marina CMI [18]

The method of determining the most common isotope of lead is by determining the average atomic mass. The formula for determining the average atomic mass is:

average atomic mass = \Sigma {percent abundance}\times {atomic mass}

Substituting the values in the formula:

average atomic mass = \frac{{203.97302}\times {1.4}+{205.9744}\times {24.1}+{206.97587}\times {22.1}+{207.97663}\times {52.4}}{100}

average atomic mass = \frac{285.562228+4963.984004+4574.166727+10897.975412}{100}

average atomic mass = \frac{20721.688371}{100} = 207.22 amu

The most common isotope of lead is:

Lead - 207.22 amu

The atomic symbol of lead is Pb. The atomic number of Pb is 82.

So, the the most common isotope of lead can be written as:

_{207.22}^{82}Pb and Lead - 207.22 amu.

Which diagram shows a wave with the highest frequency? Chemistry question.
notsponge [240]

The correct answer is D

Explanation:

Wave frequency is mainly determined by the number of waves that pass through a specific point. In a diagram, this can be found by analyzing the number of crests (top of the wave) and the space between them. For example, wave B is the one with the lowest frequency because there is only one crest and this shows only one wave passing at a specific point. On the opposite, wave D is the one with the highest frequency because this shows multiple crests and this indicates the frequency is high or that many waves pass through a specific point in a short time.
