CyclicStereoisomers. In the case ofcycliccompounds, the free single bond rotation is restricted. As a result,cycliccompounds contain several specific characteristics. Definition. If the substituents are on the same side of the ring, they are called cis.

This is due to release of carbon diaoxide gas. It is a odourless and colourless gas.

When sodium carbonate reacts with ethanoic acid, salt, water and CO2 gas is released.

Five cyclic isomers of C5H10 are possible.

These are cyclopentane, methyl cyclobutane, ethyl cyclopropane, cyclopropane, cis-1,2-dimethyl cyclopropane.

They key to the iodoform test is first being able to deprotonate hydrogens on a methyl group beta to a carbonyl group (this is possible because after deprotonation, the resulting negatively charged beta carbon will be in resonance with the carbonyl carbon).

Formaldehyde has no beta hydrogens to deprotonate (both hydrogens are directly attached to the carbonyl carbon), so they will not deprotonate, and will therefore not undergo the iodoform test.

H2SO4 is called as Hydrochloric acid.

White vitriol is the compound known as zinc sulphate

Which has the formula ZnSO₄

mass percent = (mass of element in 1 mole of compound / mass of 1 mole of compound) x 100

mass of Zn = 65.4mass of S = 32mass of O = 16

There mass of 1 mole ofZnSO₄

= 65.4 + 32 + (16×4)= 161.4

% mass of zinc = 65.4/161.4 × 100% = 40.5%

The most commonly encountered form of this compound is zinc sulphate heptahydrate

Formula: ZnSO₄.7H₂O

mass of 1 mole of it is 161.4 + (18x7) =287.4

% mass of zinc in the heptahydrate = 65.4/287.4× 100% = 22.76%

Amount of solute is 15% ( w/v) ∴ 15g of solute (H₂SO₄) is present in 100 mL of solution But density of solution is 1.1 g/cm³ Hence, mass of solution = volume of solution × density of solution= 100mL × 1.1 g/mL [ ∵ 1cm³ = 1 mL ] = 110g

∴ mass of solvent = mass of solution - mass of solute = 110g - 15g = 95g

Now, molality = mole of solute × 1000/mass of solvent in g = {weight of solute} × 1000/molecular mass of solute × mass of solvent = 15 × 1000/98 × 95 [ ∵ molecular mass of H₂SO₄ = 98 g/mol= 1.61

Hence, molality = 1.61

Chlorine is an o/p-directing group.Actually, the chlorine is electronegative species but it has lone pair of electrons which has tendency to be added in resonance structure of benzene ring and, so these lone pair electrons arises the partial -ve charge on ortho and para position so that the electron density is minimum at meta position.Now, we know that when sulphuric acid is added to this compound the mechanism follows electrophile (SO3)attacks and since it it will approach to the position with more electron density and thus it attacks on -ve , ortho /para positions and so the result obtained is ortho and para chloro sulphonic acid.

Density of solution d (1g/L)

volume of solution(water) V

mass of H2SO4dissolved = 1% of total mass of solution = 0.01dV

mass per litre of H2SO4 0.01dV/V = 0.01 * 1g/L

Molarity of solution = mass perlitre of H2SO4 dissolved / equivalent weight of H2SO4 = 0.01 * 1 / 49 = 0.0002 M

Na+ is a positively chargedsodiumion. Normally an atom ofsodium has11 electrons, so according to formula ithas2 electrons inK shell, 8 electrons inL shelland 1 electron in M shell.Hence it is said ' Na+has completely filled K and L shells.

P₁ = 1P₂ = ?

V₁= 500 dm³V₂= 200 dm³

Apply boyle's law p₁V₁=p₂V₂ to calculate p₂ as temperature remains constant.

p₂ = p₁V₁/ V₂ = 1 bar× 500 dm³/ 200 dm³ = 2.5 bar

2.5 is the required answer

1 atom of He = 4 u of He

4 u of He = 1 Atom of He

∴ 32 u of He = 1/4 × 32 = 8 atoms

Rate of heat flow from higher temperature to lower temperature.Rate of heat of transfer between two hot or cold body depends upon the temperature difference between them. That mean higher the difference higher will be heat transfer rate from hotter to colder body.

In Beaker A Temperature difference is 20C But Beaker B is placed in open area so it wil cool down itself in 5 minute and when we add water the temperature difference would be less than 20C

So Beaker A will cool down itself rather than Beaker B because of higher temperature difference. So temperature of B will be greater than as that of A

The mass number (symbol A, from the German word Atomgewicht (atomic weight), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. ... The mass number is different for each different isotope of a chemical element.

हीरा ओर ग्रेफाइट दोनो ही कार्बन से बने हुए पदार्थ है। दोनों में अंतर उनकी बनावट का है। जहाँ हीरे में कार्बन के अणु बहुत ही पास और एक के ऊपर एक व्यवस्थित होते है और उसने अणुओ के बीच मे न के बराबर खाली जगह होती है जिसकी वजह से हीरा बहुत ही सख्त होता है, वही दूसरी ओर ग्रेफाइट में अणुओ के बीच मे खाली जगह होती है और वह बहुत मुलायम होता है हीरे के मुकाबले।हीरा में जहाँ चमक होती है वही ग्रेफाइट बिजली का संचार कर सकता है जो हीरा नही कर सकता

Answer:3)CO

Explanation:Carbon monoxide is a compund whichconsists of carbon and oxygen. The formula isCO(C is carbon and O is oxygen). Each molecule consists of one carbon and one oxygen joined together. It is not anelement, but is made of two elements, carbon and oxygen, joined together

CO represents a compound and others are element

CO is the correct answer of the given question

CO is answer of the question

1.Neutronsare in every atom (with one exception), and they're bound together with otherneutronsandprotonsin the atomic nucleus. ... When youcomparethe masses ofelectrons,protons, and neutrons, what you find is thatelectronshave an extremely small mass, compared to eitherprotonsorneutrons.

2.According to J.J. Thomson’s model of an atom, an atom consists of a positively charged sphere with electrons embedded in it. However, it was later found that the positively charged particles reside at the centre of the atom called the nucleus, and the electrons revolve around the nucleus.

i. Thecolourof theclear sky is bluebecause molecules in the air scatterbluelight from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orangecoloursbecause thebluelight has been scattered out and away from the line of sight.

ii. The primary reason why the colorredis used fordanger signalsis thatredlight is scattered the least by air molecules.

The effect of scattering is inversely related to the fourth power of the wavelength of a color.

Soredlight is able to travel the longest distance through fog, rain, and the alike.

Dams are said to be an important source of water supply and high importance for various other reasons. They supply the water for the various means including domestic use, irrigation purposes and also for the industrial uses.

Dams are also involved in the hydroelectric power generation and in the river navigation. The application of these dams is much more important in daily activities including cooking, cleaning, bathing, washing, drinking water, for the gardening and for the cultivation purpose.

The big dams and the reservoirs also provide recreational areas for the purpose of fishing and also boating. They also cater the insecurity needs of humans by reducing or by preventing the floods. During the times of excess flow of water, the dams store the water in the reservoir; later they release that water during the times of low flow, also when the natural flows of water are inadequate to meet the demand.
