If two molecules are enantiomers, the absolute configuration of EVERY stereocenter is inverted going from one enantiomer to the other. ... There are also CLASSES of molecules that are chiral but have no stereocenters (we'll be IGNORING these). Likewise, molecules may have stereocenters but be ACHIRAL.

It is concluded that CHARGED particle is a particle that carries an electric charge. In atomic levels, the atom consists of NUCLEUS around which the electrons turn. ... The ELECTRON carries a negative charge (−1.602 × 10−19 COULOMBS). An atom is called NEUTRAL if the number of protons equals the number of electrons.

The ANSWER is A. Explanation:The energy of the electron in a hydrogen atom has a negative sign for all POSSIBLE ORBITS. This negative sign MEANS that the energy of the electron in the atom is lower than the energy of a free electron at rest. ... Thus it is ASSIGNED the energy value of zeroMark my answer as the brainliest!

m ONLINE what about you

no sorry BYY GOOD NIGHT sweet DREAMS take CARE byy

The carbocation bonded to three alkanes (tertiary carbocation) is the most STABLE, and thus the correct answer. SECONDARY carbocations will REQUIRE more energy than tertiary, and primary carbocations will require the most energy.Explanation:please THANK me and mark me as brainlist

tion:Certain ELEMENTS have more than one valency. They exhibit variable valency. For example, COPPER, TIN, iron and mercury exhibit variable valency. Copper combines with oxygen to form cuprous oxide (Cu2O) and cupric oxide (CUO).I'm not a beggar just a sweet #spammer

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, ALTERNATIVELY, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in GENERAL, are not REVERSIBLE except by further chemical reactions

Chemistry is the BRANCH of science that deals with the PROPERTIES, composition, and STRUCTURE of elements and COMPOUNDS, how they can change, and the energy that is released or absorbed when they change.

dge length = 286.65pm Density = 7.87gcm⁻³atomic mass = 56uTo find:Avogadro's number SOLUTION:Iron has bcc unit cell means, Z = 2 here, Z = number of atoms PER unit cell FORMULA used for density is -        here, Z = no. of atoms per unit cell          M = atomic mass          a = edge length           D = density          Na = Avogadro's number So, by SUBSTITUTING the values we get,                   Therefore, avogadro's number is 6.022 × 10²³ mol⁻¹.

Manganese exhibit the largest number of oxidation states. It shows the oxidation states +2, +3, +4, +5 ,+6, and + 7. The reason for that is the maximum number of unpaired electrons PRESENT in its OUTERMOST SHELL i.e. 3d54s2.

tion:the PHASE of the HEARTBEAT when the heart MUSCLE contracts and pumps blood from the chambers into the ARTERIES.

tion:A covalent bond is a CHEMICAL bond that involves the SHARING of electron pairs between ATOMS. These electron pairs are known as SHARED pairs or bonding pairs, and the stable BALANCE of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

There are 9 classifications with these wastes listed below:Class 1: Explosives.Class 2: Gases.Class 3: Flammable Liquids.Class 4: Flammable SOLIDS or Substances.Class 5: Oxidizing Substances and ORGANIC Peroxides.Class 6: Toxic and Infectious Substances.Class 7: Radioactive.Class 8: Corrosive Substances.Hey MATE!!!! Here is your answer ♣️

tion:FACTORY pollution is OFTEN thought of as those mostly visible and smelly smokestack emissions. ... The most COMMON factory air pollutants are greenhouse gases from the burning of fossil FUELS. Factories contribute to water and land pollution by acidifying rain, chemical spills and disposal of TOXIC waste.

Some of the environmental problems are pollution, soil erosion leading to FLOODS, salt deserts and sea recedes, DESERTIFICATION, landslides, change of river directions, extinction of species, and vulnerable ecosystem in PLACE of more complex and stable ecosystems, depletion of natural RESOURCES, WASTE accumulation,etc please mark brainliest

1-chloro-2-phenylethane is Ph-CH2-CH2-Cl, and if it undergoes the SN1 reaction, the intermediate would be Ph-CH2-CH2(+). Because of the intervening CH2 group, the carbocation that would be formed is an ordinary primary carbocation. So the SN1 reaction will not occur in 1-chloro-2-phenylethane, except perhaps under forcing (HIGH TEMPERATURE) conditions and even then, the carbocation is likely to undergo rearrangement.Benzyl chloride, Ph-CH2-Cl, FORMS the intermediate Ph-CH2(+), and here the carbocation is stabilized by resonance with the benzene ring. [Exercise: draw the four resonance structures of Ph-CH2(+).] This makes benzyl chloride the more REACTIVE towards SN1 reactions.

Mix some salt in water in a conical flask or BEAKER or any other glass equipment of your choice. This can be done by continuous stirring using a glass ROD and can be AIDED by heating the water over Bunsen BURNER. Boil the salt-water MIXTURE over Bunsen Burner till all the water evaporates. Allow the flask to cool down.Explanation:mark as brainliest

Air pollution can also cause headaches, dizziness, and NAUSEA. Bad SMELLS made by factories, GARBAGE, or sewer systems are considered air pollution, too. ... Long-term HEALTH effects from air pollution include heart disease, LUNG cancer, and respiratory diseases such as emphysema.
