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.

Water vapor is not usually seen.

xeze [42]

Answer:

True

Explanation:

Water vapor is totally invisible.

Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form. All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow.

What is the boiling point of 0.464 m lactose in water? (Kb of water = 0.512 oC/m). Enter your answer to 3 decimal places.

kirill [66]

Answer:

Boiling point for the solution is 100.237°C

Explanation:

We must apply colligative property of boiling point elevation

T° boiling solution - T° boiling pure solvent = Kb . m

m = molalilty (a given data)

Kb = Ebulloscopic constant (a given data)

We know that water boils at 100°C so let's replace the information in the formula.

T° boiling solution - 100°C = 0.512 °C/m . 0.464 m

T° boiliing solution = 0.512 °C/m . 0.464 m + 100°C → 100.237 °C

Calculate the frequency of light having a wavelength of 425nm. remember that 1nm=1×10−9m

Gnom [1K]

The frequency of light having a wavelength of 425nm will be 70588 × $10^{14} Hz$ .

The count of times an event takes place per unit of time is known as its frequency. The word frequency would be most frequently used to describe waves in physics including chemistry, including light, sound, including radio waves. The frequency refers to the number of times during one second that a point on a wave crosses a fixed reference point.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places in the consecutive cycles.

Given data:

wavelength = 425nm = $425 * 10^{-9} m$

Frequency can be calculated by using the formula;

Frequency = speed of light / wavelength

Frequency = 3 × $10^{8} m/s$ / 425 × $10^{-9} m$ = 7,0588 × $10^{14} Hz$ .

Therefore, the frequency of light having a wavelength of 425nm will be 70588 × $10^{14} Hz$ .

Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called ____

katen-ka-za [31]

The given blank can be filled with isomers.

The isomers in chemistry refers to the molecules or ions with similar formulas, but different compositions. The isomers refer to the molecules that exhibit the same chemical formula, however, distinct three-dimensional shapes. Though isomers do not always share identical properties. The two prime forms of isomerism are stereoisomerism or spatial isomerism and structural isomerism or constitutional isomerism.
