tion:Total number of ANGULAR NODES PRESENT in 3P orbital is;7

tion:In 1911 Ernest Rutherford who performed many experiments to explore radioactivity did an EXPERIMENT in which he DISCOVERED that the atom must have a concentrated POSITIVE center charge that contains most of the atom's mass. He SUGGESTED that the nucleus contained a particle with a positive charge the proton.

tion:The definition of an ATOM is the SMALLEST component of an ELEMENT, characterized by a sharing of the CHEMICAL properties of the element and a nucleus with neutrons, protons and electrons.

tion:TEST tubes CONTAINING dilute ACIDIFIED potassium manganate (VII) solution (left) and potassium manganate (VII) solution that has been DECOLOURED by sulphur dioxide gas (right). As sulphur dioxide de-colours potassium manganate (VII) solution, this reaction can be USED as a test for the presence of sulphur dioxide.

Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The RESULTING solution is basic because of the dissolved hydroxide. ... During the reaction, the sodium metal may WELL become so hot that it catches fire and BURNS with a characteristic ORANGE colourA carbon–oxygen bond is a polar covalent bond between carbon and oxygen. Oxygen has 6 valence electrons and prefers to EITHER share two electrons in bonding with carbon, leaving the 4 nonbonding electrons in 2 lone pairs :O: or to share two pairs of electrons to form the carbonyl functional group

I THINK THREE MOLECULES will be FOUND because the one MOLECULE of the hydrogen and two molecules of the

d 12 caratbecause 100% pure gold is 24 carat so 50% will be 12

ZincExplanation: A standard DRY cell comprises a ZINC anode, usually in the form of a cylindrical pot, with a carbon cathode in the form of a central ROD. The electrolyte is ammonium chloride in the form of a paste next to the zinc anode.... Follow meh..!!

The answers are as follows:Explanation: 1. it is a MIXTURE of copper carbonate and copper hydroxide.2.Basic3. Hydrogen 4.basic5. METALS are used for ringing BELLS because they are sonorous.6. phosphorous is kept under water because it is a very reactive NON metal and when exposed to air, catches fire faster. so, to prevent ignition it is stored in water.7. it is so because iron is more reactive than copper.

tion:WATER WANTS to be COLD therefore it BECOMES cold in beaker

tion:when when we heat candle it starts melting and when we cool the HEATED WAX again it FORMS wax as this is a physical process.HOPE IT HELPS YOU!!!

tion:There are 4 variables in GAS laws-the first one is pressure P for pressure and it's SI UNIT is pasccal. it is created by retain the walls by molecules of gases.V for volume and it's SI unit is. volume is not fixed in gases . Volume in chemistry is often measured in litres.T for temperature and it's SI unit is Kelvin. Although the SI unit of temperature is Kelvin but most of the time temperature is calculated in degree celsius.last last variant of gases is mole. the symbol to represent moles is mol.

due to more KINETIC energyExplanation:because the sulphuric ACID CONTAINS more kinetic energy.so the water becomes hot when we add some sulphuric acid

Because in gases MOLECULES are far away from each other and it's weight is less so it's density is less than SOLID and and liquidbecause in solid molecules are close to each other and in liquid LITTLE farer

equation should be BALANCED to verify the law of conservation of mass . This law says that after chemical REACTION ATOMS cannot be DESTROYED. eg. 4Na +O2 GIVES 2Na2O

1).The balanced equation for the above reaction is as follows:=) 2H2+ O2------) 2H2OFrom the above its clear that 2 mole H2 reacts with 1 mole O2.Molar mass of H2= 2gMolar mass of O2= 32gThis implies, 4g H2 reacts with 32g O2=) 3g H2 reacts with =) (32/4)× 3g of O2=) 24gAs the given amount of O2 is more required therefore O2 is excess Reagent & H2 is limiting Reagent.(2).2 mole of H2 gas reacts with to form 2 mole of water molecule therefore,=) 4g of H2 produces = 36G of waterSo, the amount of H2O PRODUCED by 3g H2 = (36/4)× 3= 27gHence, 27g of water will be produced during this reaction.(3).As, 24g of O2 has been UTILISED during the reaction & 29g of oxygen was supplied therefore AMOUNTS of O2 gas left is (29-24) = 5ghope it helps ☺️

System - System in chemistry is defined as the study of a set of substances and energy. For example consider an experiment in a jar , the reaction occurring in the jar and the whole THING in the jar is the system.The PROPERTIES of a system MAY be CHEMICALLY combined to PERFORM reactions and mathematically combined to find the relation between them. The relation can be deduced d) all of the above three.

it's MOLECULAR WEIGHT is 2856

e, ❤The MODEL that states the atom is a SPHERE of positive charges and the ELECTRONS are spread out INSIDE it​Ans:J. J. THOMSON'S MODEL!!

☺ HERE IS YOUR ANSWER ☺ OPTION (1) IS THE CORRECT ANSWER CAO < SRO MgO ✔✔HOPE IT'S HELP YOU ✌ ❤ ❤

so what are you EXPECTING ANSWER as there is no QUESTION

sigma bond is formed bw SINGLE bonds and PAI bond is formed be DOUBLE,TRIPLE bond .

tion:4 option because of first PEROXIDE will COME then ozone and on last oxygen

tion:A COORDINATE BOND is basically a covalent bond where both ELECTRONS COME from the same atom.covalent bond is one where both the atom share a PAIR of electrons.

On the basis of Heisenberg's UNCERTAINTY principle, it can be shown as to why electron cannot exist within the atomic nucleus. The radius of the atomic nucleus is of the ORDER of 10-15 m. Now, if the electron were to exist within the nucleus, then the maximum uncertainty in its position would have been 10-15 m.Mass of electron, m = 9.1 x 10-31 kg, Dx =1 x 10-15 m.The value of uncertainty in VELOCITY, Dv is much HIGHER than the velocity of light (3.0 x 108 ms-1) and therefore, it is not possible. Hence an electron cannot be found within the atomic nucleus.Explanation:(●'▽'●)ゝHope this HELPS uh☺
