Answer:

projection. Newman. projection. 3D STRUCTURE. A Newman projection, USEFUL in ALKANE stereochemistry, VISUALIZES the conformation of a CHEMICAL bond from front to back, with the front atom represented by a dot and the back carbon as a circle.

Answer:

In chemistry, a carbene is a MOLECULE containing a neutral carbon atom with a valence of TWO and two UNSHARED valence electrons. ... The term "carbene" may also refer to the SPECIFIC compound H2C:, also called methylene, the parent hydride from which all other carbenecompounds are formally derived.

Answer:

Cycloalkenes are HYDROCARBONS containing a ring of carbon ATOMS and ONE or more double bonds in the cycle that do not FORM an aromatic ring (a cyclic molecule is considered to be aromatic when it follows Hückel’s rule, which requires that the number of π electrons EQUALS 4n+2 where n is an integer).

ANSWER:

so what is question

I didn't UNDERSTAND what is this

ANSWER:

AL3+,CU2+,H+,li+

Explanation:

The correct order of boiling point as well as melting point of 15th group element hydride WOULD be

Bi>N>Sb>As>P (according to melting point)

The melting point increases upto arsenic and then DECREASES upto bismuth.

Thus melting point of group 15 increases down the group but its melting point decreasing at Sb and Bi due to the INERT pair of effect .

& the correct order of boiling point would be N>P

The boiling point of grou 15 hydrides decreases from ammonia to phosphine and then increases from phosphine to bismuth

Answer:

ADDITION reaction

An addition reaction is essentially a reverse decomposition reaction wherein a decomposition reaction is a reaction where one COMPOUNDS one or more elements or compounds. Looking at an example of an addition reaction, HYDROCHLORINATION of propane (an alkene), for which the equation

Substitution reaction

A substitution reaction is a reaction between molecules where an atom or a group of atoms replaces a current atom in the original MOLECULE. For example, a hydrogen atom might get KICKED off so that a different atom can be put on. There are two types of substitution reactions: nucleophilic and electrophilic.

Answer:

1 ) the process of coting of IRON with zinc is CALLED GALVANIZATION

ANSWER:Where is the QUESTION

ANSWER:

OPTION C is the answer.

Heya ,

Your answer is b .

Explanation -: Metallic character refers to the level of reactivity of metal . Metals tend to lose ELECTRONS in CHEMICAL reactions , as INDICATED by their low IONISATION energies. Within a compound , metal atoms have a relatively low attraction of electrons . This is indicated by their low electronegativities .

MELODY KHAOO.. KHUD JAAN JAO XD

ANSWER:

if in question O2 than answer is 1760 MOLE or if in question O is only than Answer would be 2520

Answer:

2FECL2 + SNCL2 -------> 2FeCl2 + SNCL4

The carbon is sp³ hybridised and IDEALLY it should have a tetrahedral SHAPE and a bond angle of 109°28'

But due to the presence of a lone PAIR of electron the angle becomes 107°

Explanation:

no of carbon atoms

Reactivity series REFERS to a series where metals are arranged based on their PROPERTY of reactive with other things.

The given metals are arranged in decreasing reactivity:

Na,MG,FE,Pb,Cu,Ag.

Explanation:

Natural gas (also called fossil gas) is a naturally occurring HYDROCARBON gas mixture consisting primarily of methane, but commonly including varying amounts of other higher ALKANES, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or HELIUM.[2] It is formed when layers of DECOMPOSING plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the FORM of chemical bonds in the gas.

ANSWER:

NOTHING...................

FULLERENE is more STABLE than DIAMOND

bcoz there is hydrogen BOND between the molecules....which MAKE it STABLE

HEYY MATE here is UR answer

plzz FOLLOW me

ANSWER:

HERE IS UR ANSWER

Explanation:

ELECTRONEGATIVITY is the PROPERTY of an atom which increases with its tendency to attract the electrons of a bond. If two bonded atoms have the same electronegativity values as each other, they share electrons equally in a COVALENT bond.

Explanation:

an organic COMPOUND derived from ammonia by REPLACEMENT of one or more HYDROGEN atoms by organic GROUPS is called AMINES

Answer:-

A pseudo first order reaction is a reaction that is truly second order but can be approximated to be first order under SPECIAL circumstances.

For example, a second order reaction of the type

A + B --> C is dependant on the CONCENTRATIONS of both A and B.

Explanation:

2. melting and boiling point and different for EVERY different physical and chemical properties melting point of water is different melting point of solid is different liquid is different everything has different melting point and boiling point but melting point of anything is means when he is solid he came in the temperature slow DANCE and melt and when boiling point is boiling point is when a water is boiled in a gas stove after sometime it becomes you operating that's CALLED a liquid of water

3.metallic character of everything is different from each other metallic character of substance five metallic character have high values of electric conductivity for example copper aluminium and silver metallic characters are cut means aluminium and magnesium can't cut with knife part sodium can be cut with knife in pieces metallic characters are having malleability of METALS like gold and silver are most malleable ductility having more and they have gold has most activity III ductile than metals are good conductor of electricity bill Tally character of any substance is depends on their hardness and softness

1 and 4 have in pic.
