state any three properties that can be used to classify elements
Answer:
The elements on the Periodic Table have been organized into groupings based on the chemical and reactive properties of the elements. The three major groups are the metals, nonmetals, and metalloids. The metals towards the left and lower parts of the Table tend to give up electrons in chemical bonding. The nonmetals to the right and upper parts of the Table tend to accept electrons in chemical bonding. The metalloids some say have an identity crisis and are a band of elements in between the metals and nonmetals which can show characteristics of the bordering groups depending on the type of bonding or chemical reaction. This group is also the foundation of our semiconductor, integrated circuit industries.Other groupings of the elements are into "families" based on the chemical nature of the elements. Some of these are the alkali metals, alkaline earth metals, transition metals, chalcogens, halogens, and inert/noble gases. There is also a semi-grouping of elements above atomic number 83 as these tend to be unstable and show natural radioactivity. Additionally, one could group the elements based on their physical states at room temperatures, such as solids, liquids, and gases.
In all both, chemical and physical properties are used to classify and group elements into useful associative collections based on these attributes. It simply depends on the purpose for the classification.

question: methanol, ch4o, is finding use as a fuel additive. describe the effect of each of the following changes on the equilibrium mixture for the combustion of methanol: a. adding more co2(g) b. adding more o2(g) c. increasing the temperature d. adding a catalyst
On adding more CO2 equilibrium shifts to left, adding more oxygen the equilibrium shift to right, increasing a temperature will shift the equilibrium to left and adding the catalyst will not affect the equilibrium.
According to Heisenberg Uncertainty Principle, if the equilibrium of a system of reaction is disturbed by making any changes in the property the reaction will shift into that direction by itself that stabilizes the equilibrium again.
According to the reaction,
CH4O + O2 = H2O + CO2 + Heat
a. Adding more CO₂ will shift the reaction towards the left side or we can say that adding carbon dioxide into the system will shift the reaction towards the reactant side. Because the concentration of carbon dioxide on the product side has increased, the equilibrium is disturbed so in order to stabilize the equilibrium again the reaction will shift towards the reactant side.
b. Adding more oxygen means that we are adding more amount of reactants which disturbs the equilibrium of the reaction so to stabilize the equilibrium again the reaction will shift towards the product side.
c. Increasing the temperature of the equation means that we are giving heat to the system which means that the equation or the system will shift toward the product side because the reaction is exothermic in nature.
d. Adding a catalyst will not affect the equilibrium of the reaction it will only increase the rate of the reaction.

water dissolves salts because it: select one: a. is hydrophobic, and salts are also hydrophobic. b. forms covalent bonds with the atoms of the salt crystal. c. has partial positive and negative charges. d. evaporates quickly at room temperature.
Salts get dissolved in water because it has partial positive and negative charges. So option (c) is correct.
Why does salt dissolves in water?The water molecules pull the Na and Cl ions apart while breaking the ionic bond which held them together. After the salt ions are pulled apart, they get surrounded by water molecules. The salt dissolves to form a homogeneous solution.
The slightly positive portion of sodium is attracted to the slightly negative portion of oxygen on the water molecule. At the same time, the slightly electronegative chlorine moieties of NaCl are attracted to the slightly electropositive hydrogen moieties of water.In either case, no true bond is formed, the stronger covalent bonds of water (also commonly held by hydrogen bonds between water molecules) win, NaCl gets pulled apart, resulting in dissociation of Na+ and Cl- ions with the Na+ and Cl- ions setting loosely in place between the intact H₂O molecules. NaCl is then dissolved.Salts are ionic and are expected to dissolve in water because water itself is polar. Therefore, ionic salts are expected to dissolve in polar solvents.

The molar mass of the other gas is 153.79 g/mol
Step 1: The Data given,
It required 57 s for 1.0 L of the gas to effuse.
Under identical experimental conditions it required 26 s for 1.0 L of O2 gas to effuse.
Step 2: Calculate the molar mass
Graham's law of effusion says:
r1/r2 = √(M2/M1)
⇒ with r1 = effusion rate 1 = L/57s
⇒ with r2 = effusion rate 2 = L/26s
⇒ with M1 = molar mass of the gas = x g/mol
⇒ with M2 = molar mass of oxygen = 32 g/mol
We should be careful if we plug in the effusion rate. Because the fractions could flip if we don't give the effusion rates as numeral values.
(L/57s)/(L/26s) = 26/57 = √(32/M1)
26/57 =√(32/X)
(26/57) ² = 32/X
0.208064 =32/X
X = 32/0.208064

1.explain why a polar aprotic solvent is used for this reaction? what is the polar aprotic solvent that is used?
Polar aprotic solvents are those solvents which have not acidic proton and polar nature.
Polar aprotic solvents are used in SN1 mechanism because these solvated both carbocation and anion .
The SN1 reaction mechanism follows a stepwise process in which the carbocation is first formed by removal of a leaving group. The carbocation is then attacked by a nucleophile. Finally, the protonated nucleophile is deprotonated to yield the desired product.
Thus, polar protic solvents help stabilize both carbocations and anions, and solvation of both cations and anions aids the progression of the SN1 mechanism. Therefore, polar protic solvents favor the SN1 mechanism.
Polar aprotic solvents are solvents that do not have acidic protons and are polar. Such solvents lack hydroxyl and amine groups. Many solvents, including chlorocarbons and hydrocarbons, can be classified as aprotic, but polar aprotic solvents are of particular interest due to their ability to dissolve salts.

The quantum theory defines a sublevel as an energy level. Sublevels in chemistry describe electron-related energies. Sublevels in physics can also refer to nuclear energy levels. A single orbital that can accommodate up to two electrons makes up the s-sublevel. Spherical best describes it. Since it is smaller than the 2s, which is smaller than the 3s, and so on, the 1s is the particle closest to the nucleus. 3 identical orbitals that resemble make up the p-sublevel.
