I don't KNOW the CORRECT ANSWER

At 0°C, water exists in solid-state. We KNOW that the freezing POINT of water is 0 °C. The LIQUID form of water starts to become solid (ICE) at this temperature.

The ATOMIC MASS unit (amu) is EQUAL to 121 of the mass of ONE atom of carbon-12 isotope.∴1 amu= 121 × mass of one C-12 atom =1.66×10 −24 g or 1.66×10 −27 kg.Explanation:please breanlit my answer and THANKS me

so SORRY EXPLANATION:I don't KNOW and GOOD MORNING

-In Thomson's model, the atom is composed of electrons surrounded by a soup of positive CHARGE to balance the electrons' negative charges, like negatively charged “plums” surrounded by POSITIVELY charged “pudding”. The 1904 Thomson model was disproved by Hans GEIGER's and Ernest Marsden's 1909 gold foil experiment.

option 4 is correctExplanation:Since,one MOLE of chlorine liberated 5 electrons.Hence, 2 MOLES will liberate 10 moles.

a) BaExplanation:Screening effect increases in the group so which ELEMENT is having SMALL ATOMIC size Ba

sock2Explanation:Which of the following can BRING about FREE radical chlorination of propane?(MULTIPLE choice)

rges constituting the electric current experience a LORENTZ FORCE. Hence the current-carrying conductor kept in a MAGNETIC field will be deflected. When the charged PARTICLE moves perpendicular to the magnetic field, the magnetic Lorentz force will be maximum.

Here is your answerThe IUPAC Name of the GIVEN compound in the given PICTURE is Ethoxy benzeneHope it's HELPFUL

tion:A CONVENIENT way of finding the direction of magnetic field associated with a current-carrying conductor is using the Right hand thumb rule. Imagine that we are holding a current-carrying straight conductor in our right hand such that the thumb POINTS towards the direction of current. Then our fingers will wrap around the conductor in the direction of the field lines of the magnetic field. This is KNOWN as the right-hand thumb rule.Let us CONSIDER that a current through a HORIZONTAL power line flows in east to west direction. Applying the right-hand thumb rule, the direction of magnetic field at a point below the wire is from north to south. The direction of magnetic field at a point directly above the wire is from south to north.Thus, when a magnetic compass is brought below the current carrying wire the compass needle show deflection in the north-southPlease mark me as brainliest.

Rutherford atomic MODEL. PHYSICIST Ernest Rutherford envisioned the atom as a miniature solar system, with electrons orbiting around a massive NUCLEUS, and as mostly empty space, with the nucleus occupying only a very small part of the atom.

The benzilic acid rearrangement is formally the 1,2-rearrangement of 1,2-diketones to form α-hydroxy–carboxylic acids USING a BASE. This reaction receives its NAME from the reaction of BENZIL with potassium hydroxide to form benzilic acid

Carbon dioxide is a chemical compound that CONSISTS of TWO oxygen atoms and one carbon atom. ... Carbon Dioxide (CO2) is a gas with a molecular structure COMPOSED of two oxygen atoms and one carbon atom. It is an important greenhouse gas because of its ABILITY to absorb infrared WAVELENGTHS.

Aqueous MEDIUM is important as acid SHOW there acidic BEHAVIOUR only in aqueous medium, and so for bases too.Mark as BRAINLIEST, it really MOTIVATES!

The definition of basicity is the condition of being a BASE, or the difficulty for an acid to react with a base determined by the NUMBER of HYDROGEN ATOMS that can be replaced in the acid.

I LOVE you your ANSWER????

yes sir I have been a long way from this my t sh are you doing well are mu kn hela KI mu emiti kichi karibani jouthipain you have a good day please find the day of school for a while AGO I am not able and pinky and Kiran god is u are receiving and giving me an UPDATE on this is the RIGHT answer to the right to appear for an update from your DVR name embedded net DVR DVR name embedded video is not available for your help me out with a great day please letter of the best regards RICHARD are mu ☺️ bhagaban ku mu na maniki you are doing well

Separation of SubstancesFiltration is the method used for separating fine insoluble solid particles from the liquid. ... Example -:Separation of insoluble IMPURITIES like soil from the water. EVAPORATION is the PROCESS of conversion of water into its vapour is CALLED evaporation.

COVID-19 is a disease CAUSED by a new strain of CORONAVIRUS. 'CO' STANDS for CORONA, 'VI' for VIRUS, and 'D' for disease. Formerly, this disease was referred to as '2019 novel coronavirus' or '2019-nCoV.'

A CONCEPT map of MATTER is a method of addressing connections between thoughts, space, MASS or words similarly that a SENTENCING chart ADDRESSES a sentence's punctuation.

The VALUE of lattice energy DEPENDS on both charge and SIZE of the ION.

a+b+c+d13+14+15+16=58 atoms524/58atoms=9.0334.

In this REACTION, the water molecule donates a proton to the NO2− ION, making OH−(aq). As the proton donor, H2O ACTS as a Brønsted-Lowry acid. In this reaction, the water molecule accepts a proton from HC2H3O2, becoming H3O+(aq). As the proton ACCEPTOR, H2O is a Brønsted-Lowry base.

hydrogen behaves like both alkali METALS(e.g. Na and K) as it shows the BEHAVIOR like these metals by losing an electron forming H+ easily which reacts with non metals like CL forming HCL and with other halogens forming acids.
