Answer:
Change the temperature and pressure
Explanation:
In case we are analyzing the solubility of a salt in some solvent, raising the temperature would increase the solubility of a salt generally. In contrast, at lower temperatures the solubility of ionic salts would decrease.
Now, another variation of this scenario might be solubility of gases. According to Henry's Law, 
, meaning that the solubility of a gas is directly proportional to its partial pressure. Therefore, the greater the pressure, the greater the solubility of a gas.
Answer:
The candy coating is made up of coloring and sugar. The coloring and the sugar molecules both have positive and negative charges on them. The water molecule has positive and negative charges so it can attract and dissolve the color and sugar pretty well.

<span>Data:
1) molar
mass: 58.0714 g.
2) mass analysis
C: 18 g
H: 3 g
O: 8 g.
Solution
</span>
<span>What is the percent composition of all the components in the liquid?
mass of C + mass of H + mass of O = 18g + 3g + 8g = 29 g
Percent composition:
C: (18g / 29g) * 100 = 62%
H: (3g / 29g) * 100 = 10%
O: (8g / 29g) * 100 = 28%
--------------
Total 100%
What is the empirical formula of the compound?
Convert masses to number of moles by dividing each mass by the atomic mass of the correspondant element:
C: 18 g/ 12.0 g/mol = 1.5 mol
H: 3 g / 1.0 g/mol = 3 mol
O: 8 g / 16 g/mol = 0.5 mol
Divide each number of moles by the smaller, i.e. 0.5 mol
=> C: 1.5 mol / 0.5 mol = 3 mol
=> H: 3 mol / 0.5 mol = 6 mol
=> O: 0.5 mol / o.5 mol = 1 mol
=> Empirical formula: C3 H6 O
What is the molecular formula of the unknown liquid?
First,calculate the molar mass of the empirical formula:
C3 H6 O => 3 * 12 g/mol + 6*1 g/mol + 16 g/mol = 58 g/ mol
Secont, given that the molar mass is the same that the empirical mass, the molecular formula is the same empirical formula.
=> Molecular formula = C3 H6 O.
This compound has been
identified as a ketone.
Go online and figure out the name of this
compound.
It is easy to find that this compound is propanone or acetone (both names are valid).
Now you can go online and find its characteristics and common uses.
Can you identify
the killer from this information? How?
Likely they think you can presume that the killer is the actress, because women use acetone regularlty to remove the nail polish.

The answer is 53.8 kJ.
Solution:There are two major steps in converting ice to liquid water. It begins with a phase change when ice melts at 0.0°C, and then a temperature change when the liquid water rises in temperature from zero to 32°C.
The amount of heat involved with the phase change melting is given by
q = (mass of water) (ΔHfus)
= (115.0 g)(334 J/g)
= 38410 J = 38.41 kJ
The amount of heat involved with temperature change is
q = mcΔT
= (115.0g)(4.184J/g°C)(32°C - 0.0°C)
= 15397.12 J = 15.39712 kJ
Summing up the two values gives the total heat required to convert ice to liquid water:
q = 38.41 kJ + 15.39712 kJ= 53.8 kJ
<span>The answer is A. This is because sunlight is composed of various wavelengths in the
electromagnetic spectrum. In the visible
light spectrum, red light has a higher frequency
(lower wavelength) than blue light that has a lower frequency (higher wavelength).
Therefore red light has higher energy than blue light hence able to penetrate
more into the atmosphere before scattering, compared to blue light. At sunrise
and sunset, due to the relative angle of
the sun to the observer, the sun rays
have to penetrate a thicker layer to the atmosphere
before reaching the observer</span>
