ANSWER:

H2 GAS is not a AIR POLLUTANT

Answer:

metals are good CONDUCTER of electricity

NON metals are BAD conducter of electricity

Answer:THATS probably the answer for the first two.

Explanation:

Though I'm not sure about the third ONE. -OH group is functional group which GETS preference over the methyl GROUPS in case of carbon numbering. So that question is probably wrong. It will be correct if its pentan-1-ol instead of pentan-4-ol

Fe2(SO4)3  is your answer because FE3+ ION in a coordination will not dissociate into Fe3+

During ionisation [disosiation] the complex compound wont break down into to INDIVIDUAL ligand and ion. The coordination sphere will stay INTACT to BEHAVE as a single ion

Answer:

to measure conductivity we can USE the conductivity meter

wash thoroughly the 250 ML beaker and electrodes with distilled water

EXPLANATION:

A AND B 4 SO A+B= 4+4=8 THEN

C AND D ARE EQUAL =2+2=4

8/4. =4

Explanation:

Monatomic ions are CHEMICALLY represented by the element's symbol with the size and TYPE of charge written as a superscript to the RIGHT of the symbol. If the size of the charge is one, then the type of charge (+ or -) is all that is written. For EXAMPLE, the magnesium 2+ ion is written as Mg2+.

Explanation:

The electrical CONDUCTIVITY of a solution of an electrolyte is measured by determining the resistance of the solution between two flat or cylindrical electrodes SEPARATED by a fixed distance. An alternating voltage is USED in ORDER to avoid ELECTROLYSIS. The resistance is measured by a conductivity meter.

Hello Mate ❤️

Answer:

=> The third law of Thermodynamics states that the entropy of a system at absolute 0 is a well-defined constant. This is because a system at ZERO temperature exists in its ground STATE, so that its entropy is DETERMINED only by the degeneracy of the lower state.✨✨✨✨✨✨

Thanks ☺️❤️

Answer:

Hi mate.

The sugarcane is CYLINDRICAL in SHAPE.

So it's volume can be FOUND by

v=πr^2h.

And if you want to convert it into litres, then divide it by 1000.(Since 1 CUBIC cm =1000 litres. )

Hope you find this useful.

ANSWER:-

✔️ Above reaction is "Williamson's ETHER synthesis"

Note:-

• in Williamson's ether synthesis Haloalkane should be 1° otherwise elimination may be possible

• if haloalkane is more then 1°, Elimination product is alkane

So, answer of your question is

1. major product of given reaction is 2-methyl propene

C(CH3)2=CH2

2. Suitable Reaction :-

C(CH3)3-Cl + CH3ONa → C(CH3)2=CH2

HCl is USED as reagent.

✅ and name of reaction is Williamson's ether synthesis.

You can find coordination NUMBER if the compound formed by them is KNOWN to you.

And coordination number mostly exist in complex compounds.

I hope you have got the ANSWER

If i am wrong then PLEASE LET me know.

ETHANE :- C2H6

Propuyne :- C3H3

If ONE MOLE mole of each GAS reacts then

C2H6 C3H3 + Na ----> C5 Na + 9/2 H2

Impossible

▪ Charles' Law states that for a mass of gas HELD at a fixed pressure, the VOLUME of the gas is directly proportional to the absolute TEMPERATURE of the gas.

Charles' Law Formula and Explanation

▪ It states that the volume of a fixed mass of a gas is directly proportional to the temperature. This law applies to ideal GASES held at a constant pressure, where only the volume and temperature are allowed to CHANGE. Charles' Law is expressed as: Vi/Ti = Vf/Tf.

ANSWER:

No, the HEAT produced by the sun is by NUCLEAR FUSION,

EXPLANATION:

no .of moles of CACO3 = 0.5

no. of moles of atoms = 0.5 ×4

= 2

no. of moles of h2s04 = 0.5

no. of moles of atoms = 0.5 × 7

= 3.5

no. of moles of ch4 = 1 mole

no.of moles of atoms = 1 × 5 = 5

no of moles of h2o = 1 mol

no. of moles of atoms = 1 × 3 moles

so, 16g CH4 xontains maximum atoms

Answer:

H2O has a tetrahedral arrangement of the electron pairs about the O atom that requires sp3 HYBRIDIZATION. Two of the four sp3 hybrid ORBITALS are used to form BONDS to the two hydrogen atoms, and the other two sp3 hybrid orbitals hold the two lone pairs on oxygen.

POTASSIUM chloride

EXPLANATION:

Potassium chloride is highly reactive and it occupies the highest position in activity series .

TWO or more than two compounds having same molecular FORMULA but DIFFERENT structural representation, or the compounds which DIFFER in ORIENTATION of atoms or groups are called as isomers and phenomenon is known as isomerism. Isomers are of two types 1- structural isomers 2-stereoisomers

Explanation:

share the same basic chemical makeup, but differ in the NUMBER of iterations of a certain aspect of their structure. HOMOLOGOUS series are REFERENCED FREQUENTLY in organic chemistry, where compounds can differ by the length of their carbon CHAIN.

Radical, also called Free Radical, in chemistry, molecule that contains at least one unpaired ELECTRON. Most molecules contain even NUMBERS of electrons, and the covalent chemical bonds holding the atoms together within a molecule normally consist of PAIRS of electrons JOINTLY shared by the atoms LINKED by the bond.

• SPECTROSCOPY is the analysis of the INTERACTION between matter and any portion of the electromagnetic spectrum. TRADITIONALLY, spectroscopy involved the visible spectrum of light, but x-ray, gamma, and UV spectroscopy also are valuable analytical techniques.

• it is used in physical and analytical chemistry because ATOMS and molecules have unique spectra. As a result, these spectra can be used to detect, identify and quantify information about the atoms and molecules. Spectroscopy is also used in astronomy and remote sensing on Earth.

• There are many different types of spectroscopy, but the most common types used for chemical analysis includes atomic spectroscopy, ULTRAVIOLET and visible spectroscopy, infrared spectroscopy, Raman spectroscopy and nuclear magnetic resonance.

What TYPE of QUESTION is this?

Answer:

As the water creeps up the PAPER, the colors will separate out into their components. ... Capillary ACTION makes the solvent travel up the paper, where it meets and dissolves the ink. The dissolved ink (the mobile PHASE) slowly TRAVELS up the paper (the stationary phase) and separates out into DIFFERENT components

ANSWER:

According to Raoult's law, when a non-volatile solid is added to the solvent its vapour pressure decreases and now it would BECOME equal to that of solid solvent at LOWER temperature. THUS, the freezing point of the solvent decreases.

ANSWER:

the CORRECT STATEMENT is OPTION C

Answer:

7 GRAM of SILVER should be DISPLACED

Bonds that are partly ionic are CALLED polar covalent bonds. Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the ELECTRONEGATIVITIES of the two atoms are equal. The result is a bond where the electron pair is displaced TOWARD the more ELECTRONEGATIVE atom.

Answer:

Hydrochloric acid :- HCl

and

SULPHURIC acid :- H2SO4.
