Summarize the chemical processes used for water treatment
Chemical processes used for water treatment:
Many processes are involved in the water treatment process to ensure that customers receive safe and healthful water. A standard surface water treatment facility includes water treatment procedures such as coagulation, flocculation, sedimentation, filtration, and disinfection.
These water treatment procedures guarantee that consumers obtain water that is both safe to drink and visually beautiful.
Water contains silt and clay, pigment bodies, precipitated iron or manganese oxides, and even bacteria and algae. These particles combine to create a foggy look in the water. Turbidity is the term used to describe this cloudiness.
Consumers abhor visible turbidity. Operators and regulators are also alerted to the presence of microorganisms in the water by visual turbidity. As a result, the Surface Water Treatment Rule mandates exceptionally low turbidity levels. Coagulation is the first step in removing turbidity.

intermolecular forces (check all that apply)
compound dispersion dipole hydrogen-bonding
hydrogen fluoride
I2
iodine
N2
nitrogen
oxygen difluoride
Intermolecular forces are forces of attraction between the different molecules of a compound.
Since hydrogen flouride, or HF, is a molar molecule, it exhibits both dipole-dipole and dispersion forces. Additionally, because fluoride has a higher electronegativity than hydrogen, hydrogen develops a partially positive charge that bonds with a lone pair of another fluorine ion to form what is known as hydrogen bonding. Therefore, it is safe to say that HF, or hydrogen fluoride, exhibits intermolecular forces like hydrogen bonding, dipole force, and dispersion force.
Iodine of I2 has a weak dispersion force and is non-polar by nature.
Since nitrogen, or N2, is a non-polar gas, its dispersion force is also relatively weak.
Oxygen difluoride, also known as OF2, is a polar molecule with a bent shape. As every molecule now has a dipole-dipole interaction, so does OF2. Additionally, every molecule with an electron has a dispersion force, so OF2 has both dipole and dispersion forces but no hydrogen bonds.

The organization has laid certain rules for nomenclature of organic compouds and we shall use those rules to derive the structure of the given compound. 4-Bromo means that a Br (Bromine group - a halogen) is attached at the 4' position of the parent chain. Here, the parent chain, having the maximum number of Carbon atoms is butane (according to nomenclature rules, but- prefix means that it has 4 Carbons in an alkane chain). Since -on (suffix) has been used, we know that a keto group(=O) has been attached. This ketone group is a primary functional group of highest priority in the functional groups present in this compound, thus, numbering of the butane chain will be such that this keto group gets the minimum number at the Carbon on which it is attached. It can't be attached on 1' Carbon, because then it would have become an aldehyde (with suffix -al). Hence, this keto group is present on 2' Carbon.

Organic molecule CH3CH(OH)CH2CH3 is the formula for the flavoring ingredient 2-Butanol, sometimes known as sec-butanol.
Sec-butanol is either polar or nonpolar?In contrast to sec-butanol, which has a significantly greater solubility, tert-butanol is miscible with water. Polar butanols, n-butanol, and isobutanol are very slightly soluble. While the longer hydrocarbon chain attenuates the polarity and decreases solubility, the hydroxyl group makes the molecule polar, which promotes solubility in water.Organic molecule CH3CH(OH)CH2CH3 is the formula for the flavoring ingredient 2-Butanol, sometimes known as sec-butanol.

Does the amount of a substance lower the freezing point and increase the melting point?
Yes, the presence of a material can cause a pure solvent (like water) to have a lower freezing point and a higher melting point. Both freezing point depression and melting point elevation are terms used to describe this occurrence.
What are the freezing point?Liquid molecules are weakly bonded, and their intermolecular forces of attraction are weaker than those of solid molecules.
This is because the molecules' potential energy, which holds them together in the crystal lattice of a solid, is smaller than the heat energy that is delivered to them during the process of changing from a solid to a liquid state.
This potential energy serves as a proxy for the solid's lattice energy.
The molecules lose their kinetic energy and approach one another when the temperature of a substance is lowered through the removal of heat from the substance or a reduction in pressure.
They gradually build more potential energy and stabilize. They turn into solids at this point. It's one of the reliable

Modern instruments have only been around for a little over 100 years. So how do we know what greenhouse gas concentrations (and temperature) were in earth's past?.
Through small slices of ice cores removed from under the Greenland Ice Sheet, we can infer information about greenhouse gases and temperature levels in the distant past.
The best source of historical climate information for scientists is ice cores. Every winter, a thin layer of snow that covers the ice sheets in the Arctic and Antarctic is left behind and turns into ice. Scientists can examine dust, ash, pollen, and trapped bubbles of air gas by removing cylinders of ice from sheets that are thousands of meters thick. The oldest known ice cores are thought to be 800,000 years old. Scientists can learn more about volcanic eruptions, the size of the desert, and forest fires by studying the particles trapped inside. Some ions can be used to determine current sea ice thickness, past ocean activity, and even the Sun's intensity. Release of the bubbles reveals the composition of the prehistoric atmosphere, including the concentrations of greenhouse gases.

Which of the following is NOT a strong electrolyte? NaNO_3 BaCl_2 H_2CO_3 H_2SO_4 All of these are strong electrolytes
Carbonic acid ([tex]H_{2}CO_{3}[/tex]) is a weak acid as for its Alpha is low so it partially dissociates in water and an equilibrium is established.
We know salts of Alkaline or alkaline Earth metals are strong electrolytes so the first two are strong electrolytes
We also know Sulphuric acid ( [tex]H_{2}SO_{4}[/tex]) is a strong acid hence a strong electrolyte
Electrolytes are ionic species which can dissociate into their constituent ions in solutions.
Alpha is a constant for particular electrolytes It determines the extent of dissociation. If alpha is high so it will fully dissociate in the solution and will be called a strong electrolyte. If alpha is low it will partially dissociate in the solution and will be called a weak electrolyte

I need help please really quick
Answer: False
Explanation:
Atoms comprise a proton with electrons that can be bonded with a neutron. Isotopes change in atomic mass due to the increase or decrease in neutrons; since neutrons always bond with protons, the number of atoms stays the same.
