Answer/Explanation:

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

A certain shade of blue has a frequency of 7.08×1014 Hz. What is the energy of exactly one photon of this light? Planck's consta

Anvisha [2.4K]

Answer:

We have the final answer as

$4.69 \times {10}^{ - 19} \: \: J$

Explanation:

To find the energy of a photon of this light we use the formula

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

f = 7.08×10¹⁴ Hz

We have

E = 7.08×10¹⁴ × 6.626 × 10-³⁴

We have the final answer as

$4.69 \times {10}^{ - 19} \: \: J$

Considering factors that affect that solubility which statement below true?

vovikov84 [41]

Answer:

Part A. The solubility of gases in water increases with increasing temperature.

Part B. Hexane (C₆H₁₄)

Explanation:

Part A

Considering factors that affect that solubility which statement below true?

With a few exceptions, the solubility of most solid solutes in water decreases as the solution temperature increases. FALSE. With a few exceptions, the solubility of most solid solutes in water increases as the solution temperature increases.
The solubility of gases in water increases with increasing temperature. FALSE. In general, the solubility of gases decreases with increasing temperature.
The solubility of a gas in any solvent is increased as the partial pressure of the gas above the solvent Increases. TRUE. According to Henry's law, the solubility of a gas in a liquid is proportional to its partial pressure.
Substances with similar intermolecular attractive forces tend to be insoluble in one another. FALSE. Substances with similar intermolecular attractive forces tend to be soluble in one another.

Part B

Which of these is the best solvent for nonpolar solutes?

acetone (CH₃COCH₃)

ethanol (CH₃CH₂OH)

hexane (C₆H₁₄)

water

There is a general rule that states "like dissolves like", meaning polar is soluble in polar and nonpolar is soluble in nonpolar. Thus, hexane, which is the least polar solvent, would be the best choice for nonpolar solutes.
