Atomic number Z = 12, Mass number A = 25 Number of protons = Z = 12 Number of neutrons = A number of protons = 25 - 12 = 13 2. Find (i) the total number of neutrons and (ii) total mass of neutrons in 7 mg of 1 4 C. Assume: mass of neutron = mass of hydrogen at..

Find the solution set of 4( w - 2) - 8 > 12 or 8 + 3(2 - w ) > 32 . => { w : w < - 6 or w > 7} or f or { w : 12 < w < 32} or { w : w < 2 or w > 3}..

Find the solution set of 5(2 s + 2) - 42 s > 39 and 29( s - 2) < 41( s - 2) . => { s : s > 39 and s < 41} or { s : s > 29 or s < 2} or { s : 2 < s < 29} or f..

Find the solution set of x x + 2 ≤ 1 2 and 4(4 - x ) > 2 x + 16 . => { x : 2 ≤ x < 16} or { x : 1 2 ≤ x < 4} or { x : x < 0} or f..

Assume that a , b , c are real numbers. Then, find the solution set for the inequality | ay + b | ≤ c for real values of y , where c < 0 . => f or { y : y ∈ real numbers }..

Molality of a solution is defined as the number of moles of solute dissolved in 1000g of a solvent. Mathematically, it is expressed as..

Molarity of a solution is defined as the number of moles of solute dissolved per litre of solution. Mathematically, Molarity is expressed by the symbol M. It can also be expressed as,..

The value of uncertainty in velocity, D v is much higher than the velocity of light (3.0 x 10 8 ms - 1 ) and therefore, it is not possible. Hence an electron cannot be found within the atomic nucleus. In 1927, Erwin Schrodinger described the behavior of electrons around the nucleus by a mathematica..

Reactants are written on the left side separated by + signs. Products are written on the right, also separated by + signs. ' D ' (the greek capital letter delta) placed over or below the arrow means that heat was added to the reactants. (g) means that the substance is gaseous. (l) means that the su..

Alkyl halides, on treating with ethanolic solution of silver cyanide, give alkyl isocyanides as the major products. Ag + facilitates the removal of halide ion. The minor product during this reaction is alkyl cyanide. It may be noted here that when treated with ethanolic solutio..
