Water can consist of hot, cold, or both to form a cloud.

With hot water, clouds will form when hot water evaporates then cools when it rises into the air. After, the warm air will expand into the atmosphere. Finally, the warm air will create water vapor that will form water droplets and create the basis of a cloud.
The temperature is very low if the water is cold. When it's cold outside, it results in a lower humidity which evaporates the water faster then it would in warm weather since the humidity would be higher. Water droplets in clouds start to form into bits of ice that fall to the earth because of the mass the ice bit has.

Best of Luck!

Calcium Carbonate Hexahydrate
(Ca C O3 6H20)

The number you would write before water in the formula for calcium carbonate hexahydrate would be 6.

Facts about Calcium Carbonate Hexahydrate:
This compound often crystallises when Essex river waters are softened by the lime/soda process. Formation of the hydrated salt is favoured by low water temperatures and by high orthophosphate levels. Calcium carbonate hexahydrate forms pure well-defined crystals which are considerably more soluble in water than calcite, the usual product of lime/soda softening.

Are bonds broken or formed, throughout each phase change present on a heating curve?

Blababa [14]

Answer:

During a phase change no chemical bonds are broken. Atoms are not rearranged because a phase change is a physical change rather then a chemical change. However, intermolecular forces are almost entirely removed from the liquid since the intermolecular forces are what cause the liquid to be a liquid.

Explanation:the nature of the intermolecular forces (IMF) will not change when the state changes from solid to liquid, however, the number of IMF changes.

Suppose that the root-mean-square velocity vrms of water molecules (molecular mass is equal to 18.0 g/mol) in a flame is found t

Zolol [24]

Answer:

$T=954.41\ K$

Explanation:

The expression for the root mean square speed is:

$C_{rms}=\sqrt {\dfrac {3RT}{M}}$

R is Gas constant having value = 8.314 J / K mol

M is the molar mass of gas

Molar mass of water vapor = 18.0 g/mol = 0.018 kg/mol

Temperature = ?

$C_{rms}=1150$ m/s

$1150=\sqrt{\frac{3\times 8.314\times T}{0.018}}$

$1322500=\frac{24.942T}{0.018}$

$T=954.41\ K$

HBr can be added to an alkene in the presence of peroxides (ROOR). What function does the peroxide serve in this reaction

RSB [31]

Answer:

Radical chain initiator

Explanation:

The peroxide here serves as a radical chain initiator. In the field of chemistry the radical initiatives are those substances that are used in industrial processes like polymer synthesis. These initiatives have weak bonds generally and they're mostly used to create free radicals. These radicals are atoms that have odd numbers of electrons. Peroxide is an example of such.

The period of a ripple on a lake is half a second. what is the frequency of the wave

Nataly_w [17]

Answer:

2 Hertz

Explanation:

The frequency would be 2 Hertz.

The frequency of a wave is defined as the rate at which the particles of a medium vibrates when the wave is passed through it while the period of a wave is the time it takes the particles to make a complete cycle of vibration.

The frequency of a wave is inversely related to its period and is defined by the following equation:

f = 1/t, where f is the frequency (in hertz) and t is the period (in seconds).

Hence, if the period of a ripple is 1/2 or 0.5 seconds, the frequency becomes;

f = 1/0.5 = 2 Hertz
