ether
ester
alkyl halide
carboxylic acid
Answer:
A.ether
Explanation:
i got it right on edg 2020 and they use ether in pokemon games to heal PP so that makes logical sense lol
The class of organic compounds that are used in anesthetics is:
A. Ether
It is a functional group consisting of C and O.
What are Anesthetics?Anesthetics are an assorted gathering of medications with especially unique synthetic designs, going from basic inorganic atoms like nitrous oxide to additional perplexing natural specialists.
Organic compound is one that contains a bond with a carbon particle. In ethers, the practical gathering that is available is C=O. Ether, as a fluid, discharges fumes that are breathed in. Another very powerful fluid sedative is propofol, controlled intravenously.
Thus, correct option is A.

Determine the mass of 2.86 mole Co(NH3)6Cl3
Answer:
765 g Co(NH₃)₆Cl₃
General Formulas and Concepts:
Reading the Periodic Table of ElementsExplanation:
Step 1: Define
2.86 mol Co(NH₃)₆Cl₃
Step 2: Define conversions
Molar Mass of Co - 58.93 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of H - 1.01 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of Co(NH₃)₆Cl₃ - 58.93 + 6(14.01) + 18(1.01) + 3(35.45) = 267.52 g/mol
Step 3: Dimensional Analysis
[tex]2.86 \ mol \ Co(NH_3)_6Cl_3(\frac{267.52 \ g \ Co(NH_3)_6Cl_3}{1 \ mol \ Co(NH_3)_6Cl_3} )[/tex] = 765.107 g Co(NH₃)₆Cl₃
mol Co(NH₃)₆Cl₃ and mol Co(NH₃)₆Cl₃ cancel outWe are left with grams (mass)Step 4: Simplify
We are given 3 sig figs. Follow sig fig rules.
765.107 g Co(NH₃)₆Cl₃ ≈ 765 g Co(NH₃)₆Cl₃

Determine the pressure of a 6.4L sample of oxygen gas at 300K and 100KPa, after the gas is compressed to 2.40L at 900K.
The pressure : 800 kPa
Further explanationBoyle's law and Gay Lussac's law
[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]
P1 = initial gas pressure (N/m² or Pa)
V1 = initial gas volume (m³)
P2 = gas end pressure
V2 = the final volume of gas
T1 = initial gas temperature (K)
T2 = gas end temperature
The pressure after the gas is compressed :
[tex]\tt \dfrac{100\times 6.4}{300}=\dfrac{P_2\times 2.4}{900}\\\\P_2=800~KPa[/tex]

Explanation:
what happens to the electronegatity when you go from top to bottom on the periodic table?
Answer:
It decreases
Explanation:
As you go down a group from top to bottom, the electronegativity decreases. Across a period, electronegativity increases from left to right.
Electronegativity is the tendency with which the atoms of the element attracts valence electrons in a chemical bond. The more electronegative an element is, the stronger its affinity for electrons. Electronegativity values less than 2 shows an element is a metal. Metals are generally electropositive.When would it be appropriate to use a model instead of a controlled experiment

Explain how Earth is heated through radiation
Answer:
Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.
If you wanted to change the polarity of hydrogen bromide (HBr) by substituting the bromine by a different atom. Which atom would increase the polarity of the molecule?
Answer:
Chlorine
Explanation:
The Polarity of an atom is characterized as the dipole to dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule. Thus, the 'chlorine' atom would help in enhancing the polarity of hydrogen bromide(HBr) with 3.16 electronegativity as we know, the electronegativity increases if we move upwards in the periodic table.
There are several differences between chemical and physical changes. Which process is a sign of a chemical change? A. Rotting potato gives all of bad smell
B. Melting block of ice leaves a large puddle
C. A cloud quickly changes shape when blown by wind
D. A plaster statue breaks when it falls into the floor. PLEASE HELP
Answer:
A. a rotten potato gives all of bad smell
Explanation:
B,C,D are all physical changes because we can reverse them back.we can cool the water back to make ice. if the wind passes again we can randomly get the same cloud shape in c. and in d we can make that statue again. but in A can we reverse the rotting process ? ( the enzyme reaction) no we cant because it is a chemical reaction it gives a bad smell because of the chemical changes occuring in it.

True or False: Plants don't have brains, but they still adapt to their environments.
Answer:
True
Explanation:
I just took that last year, and got a100%
True, Plants don't have brains, but they still adapt to their environments.
What is adaptation?Adaptation is a process where they are changing their nature to suit the environment.
We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.
Hence, plants have no brains, but they still adapt.

How much energy is required to raise the temperature of 0.2 kg of aluminum from 15°C to 18°C? (Refer to table of specific heat values.)
The amount of energy which is required to raise the temperature of 0.2 kg of aluminum from 15°C to 18°C is 49,545 J.
How do we calculate absorbed energy?Amount of energy absorbed by any material will be calculated by using the below equation:
Q = mcΔT, where
m = mass of aluminum = 0.2 kg
c = specific heat of aluminum = 897 J/kg.K
ΔT = change in temperature = 18 - 15 = 3°C = 276.15 K
On putting these value on the above equation, we get
Q = (0.2)(897)(276.17) = 49,544.89 = 49,545 J
Hence required amount of energy is 49,545 J.

How did you organize the tiles in part A? Describe the method that you used.
Answer:
I ordered the tiles from left to right and top to bottom as the numbers kept increasing. The tiles were also organized based on the color and shape that they were. The tiles with the same color and shape were arranged in the same column.
Explanation:
In the modern periodic table, the elements are listed in order of increasing atomic number and elements having similar chemical properties naturally line up in the same column (group).
Based on the quantity as well as shape of each tile, arrange them in the table.
What is tile?The majority of the time, tiles are thin, square usually rectangular coverings made of durable materials like ceramic, stone, metals, baked clay, or perhaps even glass. They are typically put in place inside an arrangement to cover surfaces including tabletops, borders, floors, walls, and roofs.
In another definition, a tile is indeed a building material or a comparable object, such the rectangular game counters. The word comes taken from the Latin phrase tegula, which means a roof tile made of heated clay. Based on the quantity as well as shape of each tile, arrange them in the table.
Therefore, based on the quantity as well as shape of each tile, arrange them in the table.

3) Effect on Litmus paper - Dip a blue litmus paper in soda
4) Electrolysis - Add two electrodes to soda and connect a battery.
Does Soda show acidic properties?Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.
When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:
