The surface area affects evaporation because the more area exposed to air allowing water to acquire more heat energy hope this helps :)

An estimated value of 90% of the water in the atmosphere comes from Earth's water. Some water evaporates from the water on land, but the majority of the water vapor evaporates from the water on Earth's oceans. The ocean covers most of Earth's surface. As a result, the oceans receive most of the solar energy that reaches Earth.

Answer: increasing frequency or energy and decreasing wavelength.

Explanation:

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light i.e

The electromagnetic spectra consist of radio waves, microwaves, infrared ,Visible , ultraviolet, X rays and gamma rays arranged in order of increasing frequency or increasing energy and decreasing wavelengths.

Explain the two main physical/ chemical processes by which carbon dioxide molecules in the air move to the cells of phytoplankto

VARVARA [1.3K]

Answer:

The two physical/ chemical processes by which carbon dioxide molecules in the air move to the cells of phytoplankton in the ocean are the photosynthesis and the biological carbon pump.

Explanation:

The biological carbon pump is the action of organisms to move carbon during chemical and biological interactions from the surface into the deeper ocean and then to rocks.

The biological carbon pump its composed of three processes, which are the photosynthesis, the gravity and the food web interactions. They are all part of the carbon cycle.

During the photosynthesis, the phytoplankton take up carbon dioxide from the atmosphere that is dissolved in the surface water, and receives the energy from the sun to turn it into glucose and oxygen.

In the cells of the phytoplankton, glucose is transformed into other organic compounds. This material has organic carbon that can end in two ways: it is incorporated to marine organisms during the food web interactions or it can be remineralised forming calcium carbonate in the ocean surface.

The remineralization can be done by many organisms to build its shells or skeletons, or by chemical processes that happen in the ocean. This process allows more carbon dioxide to enter the water and to continue the cycle.

So when marine organisms die, all its organic components sink into the bottom of the ocean and carbon-rich sediments are form. And after millions of years, these sediments turn into rocks after going through chemical and physical phenomenon.

snow_tiger [21]

Answer:

$7.45\times 10^{26}$ photons are emitted per second in a $1\times 10^3$ Watt microwave oven.

Explanation:

The expression for the power is:-

$Power=\frac{Energy}{Time}$

Also, $E=n\times \frac{h\times c}{\lambda}$

Where,

n = the number of photons

h = Plank's constant having value $6.626\times 10^{-34}\ Js$

c = the speed of light having value $3\times 10^8\ m/s$

$\lambda$ = the wavelength of the light

So,

$Power=\frac{n}{Time}\times \frac{h\times c}{\lambda}$

Thus, the expression for photons per second is:-

$\frac{n}{Time}=\frac{Power\times \lambda}{h\times c}$

Given that:-

Power = 10³ Watt

( 1 cm = 0.01 m)

[/tex]

So,

$Photon/sec=\frac{10^{3}\times 0.148}{6.626\times 10^{-34}\times 3\times 10^8}=7.45\times 10^{26}$

$7.45\times 10^{26}$ photons are emitted per second in a $1\times 10^3$ Watt microwave oven.

Write balanced chemical reactions for the following a) Ammonia, NH3, reacts with nitrogen oxide, NO, to produce water and nitrog

Evgesh-ka [11]

Answer:

a) 4NH₃ + 6NO ⇄ 6H₂O + 5N₂

b) 2H₂S + 3O₂ ⇄ 2H₂O + 2SO₂

Explanation:

Write the equation as given then modify accordingly.

a) NH3 + NO ⇄ H2O + N2

make sure that the amount of each element is equal in both side (reactants and products)

Hydrogen is the different one thus to make H egal we multiply by 2 in the reactant and by 3 in the product to make it 6. Thus the all reaction is multiply accordingly.

2NH3 + 3NO ⇄ 3H2O + 5/2N2

to remove the fraction, multiply both side by 2.

4NH3 + 6NO ⇄ 6H2O + 5N2

b) O2 + H2S ⇄ H2O + SO2

The Oxygen are not the same, so we make them equal to 6 in both side. in the reactant we have to multiply by 3. In the product we have to get 2 for water and 2 for SO2 to have a total of 6 O.

we modify the reaction accordingly to equal elements in both side.

2H2S + 3O2 ⇄ 2H2O + 2SO2
