Some of the negative impact of disruption in water cycle are adverse environment, with affected farming, hydroelectricity, and deforestation.
The water cycle has been operated in the environment for the conversion of water in the different states. The water cycle has been operated with the conversion of water from the water body to the clouds by evaporation.
The evaporated water has resulted in clouds, that have been condensed and precipitated in the form of rain. The water cycle helps in maintaining the water balance in the ecosystem. It made the water available for use as well.
The drought has been the condition of the scarcity of water. In this condition, there has been a disruption of the water cycle. Some of the negative impacts resulting from the disruption of the water cycle are:

what is the strongest interparticle force in a sample of so2?
Answer:
The strongest intermolecular force in sulfur dioxide is dipole-dipole forces.
Explanation:
The interparticle force in [tex]SO_{2}[/tex] (sulfur dioxide) is the dipole-dipole interaction.
What is dipole-dipole interaction?
Dipole-dipole interaction is a type of intermolecular force that occurs between polar molecules. Polar molecules have a permanent dipole moment, which means they have a partial positive charge on one end and a partial negative charge on the other end. This creates an electrostatic attraction between the partial charges of neighboring molecules. The stronger the dipole moment of a molecule, the stronger its dipole-dipole interaction will be with other polar molecules.
Dipole-dipole interactions are responsible for a variety of physical properties of substances, including their boiling and melting points. Substances with strong dipole-dipole interactions tend to have higher boiling and melting points than substances with weaker interactions. In addition, the strength of dipole-dipole interactions can affect solubility, as polar substances tend to dissolve better in other polar substances due to their ability to form dipole-dipole interactions.

1. Explain the difference between genetic, environmental, social, and pathogenic factors.
2. How do pathogens spread?
3. How can we, as humans, prevent transmission of pathogens?
4. List three ways the environment can affect personal health.
1. Genetic factors are those where the genetic condition of an individual is capable of increasing the probability of developing certain diseases.
Environmental factors include the diversity of environmental stresses such as population density, temperature, food and pollutants that impact human health.
Social factors are related to the interaction of groups through culture, social class and family structure, which also have an effect on population health.
Pathogenic factors, on the other hand, are those transmitted by agents such as viruses, fungi, bacteria and protozoa, which colonize a host by adhering to cells and evading immunity, generating diseases.
2. The transmission of pathogens can occur in several ways, such as contact with bodily fluids from infected people, cross-transmission or through being spread through particles in the air.
3. We can prevent the transmission of pathogens through proper hygiene habits, healthy eating, vaccination against infectious diseases and avoid contact with other people if you have a communicable disease.
4. The environment can affect personal health through climate change, pollution and lack of infrastructure that lead to less access to quality food and basic health conditions.

A sugar crystal contains approximately 1.4×1017 sucrose (C12H22O11) molecules. What is its mass in milligrams? Express using 2 sig figs
Answer:
Our process would be just turning the molecules of sucrose to the moles by dividing using Avogadro's number (6.02 x 10^23), which will give us the moles we need. In order to find the mass of the sucrose, you have to multiply the moles by the molar mass of sucrose in order to find the mass, and then multiply by it 1000 to change it to mg.
Here are the formulas:
Number of moles = Number of molecules / Avogadro's number
Mass = Moles x Molar mass
Number of moles = (1.4 x 10^17) / (6.02 x 10^23) = 2.3255814 x 10^-7 moles
Now that we have the moles, we can multiply them by Sucrose's molar mass, which can be calculated by using the masses listed in the periodic table.
Carbon's Molar Mass = 12g/mol (There are 12 atoms of Carbon in sucrose)
Hydrogen's Molar mass = 1.01g/mol (22 atoms of Hydrogen in sucrose)
Oxygen's Molar mass = 16g/mol (11 atoms of oxygen in sucrose)
Now we just add them together:
((12)x(12)) + ((1.01)x(22)) + ((16)x(11)) = 342.22g/mol is the molar mass of Sucrose
Now back to the question, you multiply the moles of sucrose by its molar mass to get the mass in grams
(2.3255814 x 10^-7) x (342.22) = 0.0000796 grams
Now to get it in milligrams, you multiply the answer above by 1000
0.0000796 x 1000 = 0.079 mg (already in 2 sig figs)
Therefore there are 0.079 milligrams of sucrose in the sugar crystal.
The mass of sucrose molecules is 0.079 milligrams .
How is mass calculated from number of molecules?To calculate mass of a substance wherein number of molecules is given, initially number of moles is obtained.
number of moles= number of molecules/Avogadro's number
=1.4×10¹⁷/6.022×10²³
=2.234×10[tex]^-7[/tex]
Now the mass is calculated by multiplying number of moles into molar mass of sucrose
=2.234×10[tex]^-7[/tex]×342.22
=795.31 ×10[tex]^-7[/tex] g
=0.079 mg.
The mole concept is a convenient method for expression of amount of substance in chemical applications.It is mainly focused on the quantity of mole which is a count of large number of particles.One mole of any substance is equal to the Avogadro's number .
It is useful for measuring products of chemical reaction. It is the basis of stoichiometry and expresses amount of reactants and products which are formed and consumed during the course of chemical reaction.

If you wanted to make a crucible for melting sodium (Na), which metal would be most suitable for that purpose
To make a crucible for melting sodium (Na), metals that would be most suitable for that purpose are inert metals or metals like alumina.
What are inert metals?inert metals are those metals that do not react with other highly reactive metals or in the atmosphere due to the absence of one free electron in the outermost orbital.
The sodium metal is kept in the crucible of the inert metal like alumina because sodium has one free electron in the outer shell and catches fire as come into the contact with the air.
