• In Mendeleev's PERIODIC table there were gaps for undiscovered ELEMENTS. MODERN periodic table MAINTAINS uniformity.
• In Mendeleev's periodic table noble gases were not placed (as they are not discovered at that time).
• In Modern periodic table noble gases in a seperate GROUP named as group-18.

Explanation:

A combination reaction is a reaction where two or more elements or compounds COMBINE to form a single compound. Such reactions are represented by equations of the following form: X + Y → XY.The combination of two or more elements to form ONE compound is called a combination reaction.

Answer:

2HNO3+CA(OH)2= Ca(NO3)2+2H2O

ANSWER:

OPTION C is correct

Explanation:

The reaction is FIRST order with respect to CHCl3 and first order with respect to Cl2. Hence, the overall order of reaction is 1 + 1 = 2.

The molality of the solution containing 15.20 G of UREA (MOLAR mass = 60) DISSOLVED in 150 g of water is:

Answer:

Sebacic acid is normally MADE from castor OIL, which is essentially glyceryl ricinoleate. The castor oil is treated with caustic SODA at HIGH temperature, e.g. 250°C, so that saponification, leading to the formation of ricinoleic acid; is followed by a reaction giving sebacic acid and octan-2-ol Figure 18.5.

Explanation:

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new COMPOUNDS. These reactions often involve an energy source such as HEAT, light, or ELECTRICITY that breaks apart the bonds of compounds.

NH 4Cl→NH 3 +HCl

Answer:

Formic acid is not a typical carboxylic acid; it is DISTINGUISHED by its acid strength, its FAILURE to form an anhydride, and its reactivity as a reducing agent—a property due to the ―CHO GROUP, which imparts some of the character of an ALDEHYDE. The methyl and ETHYL esters of formic acid are commercially produced.

Explanation:

Displacement reaction OCCURS when a metal from a electrochemical SERIES is mixed with the IONS of a metal LOWER down in the electrochemical series.

hope it will help you

Explanation:

Metallic corrosion includes both oxidation or exposure to oxygen in the environment and electrochemical processes, meaning the metal forms corrosion cells on its surface that greatly accelerate the TRANSFORMATION of metal BACK to the ore state, and INVOLVES both chemical REACTIONS and the flow of ELECTRONS.

दूसरे शब्दों में, किसी पदार्थ से इलेक्ट्रॉन को हटाने की प्रक्रिया को ऑक्सीकरण कहते हैं। अवकरण: यदि कोई पदार्थ हाइड्रोजन लेता है या ऑक्सीजन का त्याग करता है तो उस पदार्थ का अवकरण होता है। अवकरण की एक अन्य परिभाषा के अनुसार, किसी पदार्थ का जब हाइड्रोजन या धातु से संयोजन होता है तो उस पदार्थ का अवकरण होता है।

Question (Corrected):

Give the IUPAC name of following

Answer:

Butane

Explanation:

How to name a pure hydrocarbon:

• Recognize if it is alkane (all single bonds), alkene(at LEAST one double bond), alkyne (atleast one triple bond): Here's it's alkane so the ending will be -ane [-ene for alkene and -yne for alkyne
• Recognize the longest chain and the type : it's a straight chain of 4 carbons here so we USE beut [ METH for 1 , eth for 2 , prop for three and so on]

So the final name BECOMES Beutane.

Answer:

double displacement reaction is a TYPE of chemical reaction in which the reactant ions exchange places to form new products. Usually, a double displacement reaction results in PRECIPITATE formation. The chemical BONDS between the REACTANTS may be either covalent or IONIC.

ANSWER:

OXYGEN PROBLEM

Explanation:

oxygen problem

Answer:

Since the oxidation STATE is DECREASED thus, Pb304 is the OXIDANT. (B) O2 is the oxidising agent. Because O2 is an element and the oxidation state of any element is O. Thus, the oxidation state of oxygen is 0.

Answer:

Ionization energy exhibits periodicity on the periodic table. The general trend is for ionization energy to increase MOVING from LEFT to RIGHT across an element period. Moving left to right across a period, atomic radius decreases, so electrons are more attracted to the (CLOSER) nucleus.
