ree of unsaturation is equivalent to 1 RING or 1 double bond (1 π bond). Two degrees of unsaturation is equivalent to 2 double BONDS, 1 ring and 1 double bond, 2 rings, or 1 triple bond (2 π bonds).

It is REALLY difficultExplanation:

The orthophosphoric ANHYDROUS ACID is a white, crystalline solid which melts at 42.35°C. As PHOSPHORIC acid is heated to temperatures above about 200°C, there will be a LOSS of constituent vapours.

As this MILK is slightly more alkaline than other, therefore, acid PRODUCED to set into curd will be neutralized by baking soda added by MILKMAN. HENCE, this milk takes a longer time to set as curd.

your answerExplanation:When the REACTANTS are heated, the AVERAGE kinetic ENERGY of the MOLECULES increases. This means that more molecules are moving faster and hitting each other with more energy. If more molecules hit each other with enough energy to REACT, then the rate of the reaction increases.

C60 (fullerene) looks like a soccer ball and CONTAINS 20 SIX membered rings and 12 five membered rings of carbon atoms. Six membered rings are fused with both six membered as well as five membered rings while five membered rings are ATTACHED only with six membered rings.Hence, option C is CORRECT.

Rutherford atomic model failed to explain about the STABILITY of ELECTRONS in a CIRCULAR PATH. As per Rutherford's model, electrons revolve around the nucleus in a circular path. ... Eventually, electrons should lose energy and FALL into the nucleus. And this points to the instability of the atom.Explanation:hope it helps you❤❤

Good evening DEAR pls mark as brilliantExplanation:Reaction with limewaterCarbon DIOXIDE reacts with limewater (a solution of CALCIUM hydroxide, CA(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3. Adding more carbon dioxide results in the precipitate dissolving to form a COLOURLESS solution of calcium hydrogencarbonate.f l l o w m e

hii MATE here is your answer Explanation:Acidic soil needs to be neutralise. Quick line when REACTS with water/moisture in surrounding produces slaked lime or CA(OH)2 which is BASIC and can neutralise the soil for BETTER crops.

the CORRECT Answer.Hope, This helpsMark me as brainliest.and FOLLOW me.

e! Here is your answer:Rutherford's model was unable to EXPLAIN the STABILITY of an atom. ACCORDING to Rutherford's postulate, electrons revolve at a very high speed around a nucleus of an atom in a fixed orbit. Rutherford's theory was INCOMPLETE because it did not mention anything about the ARRANGEMENT of electrons in the orbit.Hope it helps you ✌

Coal is MOSTLY carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant MATTER decays into peat and is converted into coal by the heat and pressure of DEEP burial over MILLIONS of YEARS

Just like terpenes, the terpenoids can be CLASSIFIED according to the number of isoprene units that comprise the parent terpene: Hemiterpenoids, 1 isoprene unit (5 carbons) Monoterpenoids, 2 isoprene units (10C, i.e., derived from MONOTERPENES) Sesquiterpenoids, 3 isoprene units (15C, i.e., derived from sesquiterpenes)I hope it is helpful for you ☺☺☺☺

Explanation:1−pentene−CH  2 ​   =CHCH  2 ​   CH  2 ​   CH  3 ​     2−pentene−CH  2 ​   CH=CHCH  2 ​   CH  3 ​     (CH  3 ​   )  2 ​   C=CHCH  3 ​     is 2-methyl but-2-ene. All these contain PRIMARY and secondary hydrogen atoms and gives at least 2 MONOCHLORINATION products. Only cyclopentane gives 1 monochlorination product as only secondary hydrogen atoms are present and only one type of hydrogen can be replaced. Option D is CORRECT.

tion:The given reaction isCuO(s) + H_2(g) -> Cu(s) + H2O(l)In this reaction, copper (II) oxide reacts with hydrogen to GENERATE copper metal and water. This is an OXIDATION-reduction reaction, in which some SPECIES are oxidized and some reduced. The oxidation number of copper goes from +2 (in CuO) to 0 (in Cu), while hydrogen's oxidation number goes from 0 (in H2) to +1 (in water). The oxidation number of oxygen stays the same and is equal to -2.In oxidation, the oxidation number increases as the species lose electron(s). Since the species gain one or more electrons in reduction, the oxidation number decreases. Thus, hydrogen is oxidized while copper is reduced. We can also say hydrogen is the reducing agent, while the copper (II) oxide is the oxidizing agent. Hope this helps.

the empirical formula of X is CH2.Explanation:the SIMPLEST RATIO of atoms is present in the empirical formula.and the total number of all types of atoms is INDICATED in the MOLECULAR formula

Because atoms themselves are assembled from particles that have their own properties.They don't really care that they participate in CREATING atoms, that is just a kind of social phenomenon in their own society. And as you know in social phenomena relationships come and go. It just so happens that when the universe cooedl down to a reasonable kind of temperature that certain of these relationships were able to persist.Particles have properties like mass and electrical charge and these properties are not contained in LITTLE packets, they spread out to infinity!You see that's the thing, these things we used to think about as particles are not confined at all, they just tend to pay more attention to eacother electrically, over short distances and long times. And they don't SIT in space and time like it was some kind of ocean either.As a result at the temperatures we are used to the masses of the particles is very unbalanced but the electrical charges are equal and opposite. So we get heavy positive particles that are not so easy to move around and act as the social centre of attention and lightweight negative particles that tend to be highly promiscuous.We call the positive plus neutral charged collected mass of particles the nucleus, and we call the promiscuous negative particles electrons and the net result of them cohabiting in the same space as to self assemble into things we call atoms.Most of the electrons around the nucleus are actually in a stable configuration but the one or two electrons on the outside MAKE all the difference to the relationships between the atoms, and we calll these the VALENCE electrons.These valence electrons give rise to most of the everyday properties of matter as we know it, including all the colour and electrical properties and the heat conductivity and the physical strength you name it.it's amazing that so many properties and the bulk of matter can all be traced back to such simple size and scale and behaviour of a few silly particles.

nfo : 50g of CaCO3 decomposes on HEATING to GIVE cao and 20G off CO2 gas. To find : the approximate purity of CaCO3 is....Solution : decomposition of CaCO3 is .. CaCO₃ ⇒ CaO + CO₂here we see 1 mole of CaCO3 decomposes into 1 mole of CaO and 1 mole of CO2. 100G of CaCO3 decomposes into 56g of CaO and 44g of CO2. [ molecular WT of CaCO3 = 100g molecular wt of CaO = 56g molecular wt of CO2 = 44g ]So, 20g of CO2 is produced by 100/44 × 20 g = 45.45 g Therefore the impurity in 50g of CaCO3 sample = 50 - 45.45 = 4.55gtherefore percentage purity of CaCO3 = 45.45/50 × 100 = 90.9 ≈ 91 %
