In the beginning the rate of reverse reaction is |
|
Answer» Answer: Is simply the reverse reaction of oxidative ADDITION; the formal VALENCE state of the metal is reduced by two (or one, in a bimetallic reaction) and the total electron count of the COMPLEX is reduced by two. While oxidative addition can also be observed for main group elements, this reaction is more TYPICAL of the transition elements in particular the electronegative, NOBLE metals. In a catalytic cycle the two reactions occur pairwise. At one stage the oxidative addition occurs, followed by, e.g., insertion reactions, and then the cycle is completed by a reductive elimination of the product. |

. When burning sulphur is taken into the cylinder of oxygen, it burns with a brilliant blueflame. Name the gas produced. What happens when this gas reacts with water. Support youranswer with the equation. |
|
Answer» Answer: Sulfur is only mildly flammable under normal ATMOSPHERIC conditions, but in pure oxygen, it burns with a very nice blue flame. The products of the combustion are sulfur dioxide and sulfur trioxide: S(s) + O2(g) ——> SO2(g) 2S(s) + 3O2(g) ——> 2SO3(g) These substances react with water in the air to produce SULFUROUS and sulfuric acid, respectively: SO2(g) + H2O(g) ——> H2SO3(g) [sulfurous acid] SO3(g) + H2O(g) ——> H2SO4(g) [sulfuric acid] This can be demonstrated by quenching the burning sulfur with a small amount of distilled water, and ADDING an APPROPRIATE acid-base indicator, such as methyl orange.
In the following demonstration, a small amount of sulfur is placed in a deflagrating spoon, heated in a Bunsen burner until it begins to burn, and then lowered into a jar of pure oxygen. The sulfur then flares up into a much brighter blue flame, and eventually begins to throw off fumes of sulfur dioxide and trioxide.

(xx) which among the following is optically active compoundans.CH2=C=CC12CH2=C=CH2CH(CH3)=C = CH(CH3)None of the above |
|
Answer» Answer: Hope it will help you Explanation: An organic compound having a carbon attached to four different GROUPS is optically active. But, is the OPPOSITE also true? That is, do all optically active organic compounds have chiral carbons? Not necessarily. Presence or ABSENCE of chiral center is not the sufficient criterion for OPTICAL activity. The ultimate criterion is presence or absence of either plane or center of symmetry. Two compounds which are non-superimposable mirror images of each other are called enantiomers. If a compound contains more than ONE chiral carbon, new words are required to describe the relationship between various stereoisomers of the compounds. Those words are diastereomers and mesomers. Optically active compounds among the following is/are (A) CH 3
−CH=C=CH 2
(B) CH 3
−CH=C=CH−CH |

(1) 100 g of hard water contains 0.00475 g MgCly. What is the hardness of water in ppm?50 ppm5 ppin500 ppm475 ppini |
|
Answer» your ans is here plz mark me as brainlist Explanation: TOTAL hardness= CA hardness + Mg hardness The calcium and Mg hardness is the concentration of Ca & Mg IONS expressed as equivalents of CaCO 3
For Mg= M Mg
M CaCO 3
= 24.3 100.1
=4.1 So total hardness= 4.1[Mg 2+ ]ppm of CaCO 3
Given 100kg of water contains 5g MgSO 4
i.e, 100L water contains 500mg of MgSO 4
= M MgSO 4
(500mg)24.3
= 120.7 (500mg)(24.3)
=100mg of Mg ims ∴[Mg 2+ ]=100mg/100L=1mg/L So hardness of water= 4.1[1mg/L] =4.1ppm of CaCO 3
