The Lassaigne's test helps to detect Nitrogen, Sulphur, and Halogens in the organic compounds. Here, sodium metal (Na) is heated in the presence of the organic compound inside a fusion tube.
The presence of nitrogen in the organic compound is detected by fusing organic compounds with sodium metal to give sodium cyanide (NaCN) soluble in water. This is converted into sodium ferrocyanide by the addition of sufficient quantities of ferrous sulphate.

<span>In a nuclear reaction, mass is converted to energy according to the famous relation E = mc^2 So the best answer is : </span><span>C. During a chemical reaction, some of the mass of the reactants is converted to energy.</span>
Hot air balloons don't have pre-planned landing spots due to the fact they travel where the wind takes them. Instead, our pilots will look for a suitable open space and bring their balloon to land in a safe and controlled manner, fully compliant with aviation law.
Molarity=Moles of soluteVolume of solution (in litres)0.25 M=n1 Ln = 0.25 molSo, we need 0.25 mol of sucrose to make 0.25 M solution.Molar mass of sucrose (C12H22O11)=342 g/mol Mass of 0.25 mol sucrose is0.25mol×342gmol=85.5 g
