A sample of water vapor condenses to form liquid water. What change in water
allows this to happen?
Answer:
Condensation is the process of water vapor condensing into liquid water.
Explanation:
"Water condenses on a can of cold soda. Water vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor." -National Geographic"

. Water is one of our most important resources. Only about 1% of the Earth's water is for human needs. Name four ways you can help conserve water. This is for science btw...
Answer:please see explanation for answers
Explanation:
Water conservation is an approach geared towards controlling how water is used. Because of the ever growing population, which weighs so much on water available to mankind,Over negligence and abuse of our water resources have been a great point of concern, that is why the need for the knowledge of water conservation is preached.
Now, some of the ways we can conserve water include
1. Putting off taps while lathering the hands with soap
2.use of irrigation system to water crops and plants
3.. while brushing, make sure to turn off the tap or faucet
4. use a shower rather than a bath
How many moles of KCl are produce when 61.5 g of KClO3 are decomposed?
Answer:
0.502mol
Explanation:
The balanced chemical equation of the reaction described in this question is as follows:
2KClO3 → 2KCl+ 3O2
According to the equation above, 2 moles of KClO3 will produce 2 moles of KCl.
Using mole = mass/molar mass to convert mass of KClO3 to moles
Molar mass of KClO3 = 39 + 35.5 + 16(3)
= 39 + 35.5 + 48
= 122.5g/mol
mole = 61.5 g ÷ 122.5g/mol
mole = 0.502mol
Since 2 moles of KClO3 will decompose to produce 2 moles of KCl.
0.502 mol of KClO3 will decompose to produce 0.502 × 2/2
= 0.502mol of KCl.
explain how the alpha particle scattering experiment led to a change in the model of the atom from the plum pudding model?
Answer:
So originally, the plum pudding model by J.J Thomson is electrons (negatively charged) held in place by a proton (positively charged) cloud.
Alpha particles are positively charged made of 2 protons + 2 neutrons.
Rutherford's experiment where they beamed those positively charged alpha particles demonstrated that an atom was not a uniform cloud, instead the alpha particles that were deflected was the positively charged nucleus. The alpha particles would also pass through if it didn't hit the nucleus, or be slightly attracted to the negative charge on the electrons. But the overall idea is that Rutherford's experiment changed what the structure of the atom was by discovering that they have a positively charged nucleus due to the deflection of positively charged alpha particles.

3/7 of a sum is Rs.1800. Find the sum
Answer:
the sum is Rs 4,200
Explanation:
Given that
3 by 7 of the sum is $1,800
We need to find out the sum
So,
Here we assume the sum be x
So the following equation should be made
3 ÷ 7 × x = 1800
3x = 1800 × 7
x = (1800 × 7) ÷ 3
= Rs 4,200
Hence, the sum is Rs 4,200
The same would be considered and relevant
how did the idea of triads influence the development of the periodic table , even though more than three elements share similar properties ?
A. It established element families
B. It established element groups numbered 1-18
C. It gave rise to the idea of the law of octave
D. It gave rise to the idea of periodicity
Johann Döbereiner identified triads of chemically related elements in 1829 and demonstrated how the properties of the middle element could be anticipated from the properties of the other two. Examples of such triads are lithium, sodium, and potassium.
How did the idea of triads influence the development of the periodic table?
Johann Dobereiner (1780–1849), a German scientist, organized diverse trios of three elements into triads in 1829.Lithium, sodium, and potassium made up one such trio.Triads were based on both chemical and physical characteristics. All known elements could fit on Mendeleev's periodic table, and it also made precise predictions about the presence and characteristics of yet-to-be-discovered elements. Mendeleev organized the elements in his first periodic table according to their masses and other chemical characteristics.Atoms' fundamental chemical structure was unknown at the time.Mendeleev increased the size of his periodic table to include every element at the time. The law of triads was discovered by German scientist Johann Döbereiner, who wrote: "If the elements with similar chemical properties are grouped in the groups of three, the atomic weight of the middle element will be deemed almost equivalent to the arithmetic mean of the two-terminal element's total." The arithmetic mean of the atomic masses of the first and third elements must be about equal to the atomic mass of the second element in order to form a Dobereiner trio.The atomic mass of nitrogen is equal to the arithmetic mean of the atomic masses of carbon and oxygen in this situation, which is 14.They so make up Dobereiner's trio.To learn more about periodic table refer

Some nuclear waste is stored about 600 meters
below the desert in New Mexico inside caverns dug
out of an ancient bed of rock salt. The land above
the storage site is owned by the federal
government. Why do you think this location was
chosen?
Answer:
This location was chosen because rock salt has qualities that can withstand the negative effects of nuclear waste and prevent it from causing any harm to the biosphere and all life in it.
Explanation
How to properly dispose of radioactive waste has always been a great problem due to its very high potential to negatively affect life in every form. There have been several kinds of research into the best ways to dispose of such waste. In times past, we have seen radioactive waste sealed up in drums and disposed of. These drums are not everlasting and can be subject to accidents, weakened by weather, etc thus creating a radioactive leak.
One of the results of the research was to store such waste away far below the ground where there are deposits of rock salt.
Radioactive waste generates tremendous amounts of heat if buried in ordinary underground sites and can contaminate underground water channels with radioactive poisoning. So if it were to be buried underground, it had to be in a site that is impregnable by water with very high resistance to heat.
It has been discovered that rock salt has very high boiling and melting points which are 1413 degrees Celsius and 807 degrees Celsius respectively. This makes the ancient bed of rock salt a preferred location by the US government for storing nuclear waste.

One very common way spores/seeds are spread is through the wind. MAny plants use this to reproduce.
Spreading seeds by burrs is not as common as the other methods of reproduction, and is never used for spore reproduction found in certain organisms.
Lastly we have organisms eating fruit and spreading the seeds. There are two ways fruited plants reproduce. Either A, they reproduce by lettign their fruit fall to the earth, and when the fruit decomposes, the seeds are realesed intot eh soil. Or B, the fruit is eaten by organisms, and spread into the soil during fecalization. The feces of the organism can even help the seeds of the plants grow.
