Hi can you please name this

A compound with a percent composition by mass of 24.61% C, 2.75% H, and 72.64% Cl has a molar mass of 439.23 g/mol. What is the molecular formula of the compound? ( C: 12 g/mol, H: 1 g/mol, Cl:35.5 g/mol)

Stearic acid (C18H 3,02) is a typical fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. It is used to make cosmetics, oin tmen ts, soaps, and candles and is found in animal tissue as part of many saturated fats. In fact, when you eat meat, chan ces are that you are inges ting some fats that con tain stearic acíd. (i) Define standard enthalpy of combustion for stearic acid (s) and write a balanced equation for the reaction. marksi (ii) Using the following standard enthalpy of formation, calculate the standard change of combustion for stearic acid.

student found a bottle of unknown origin in the basement of an "CAUTION—contains С₁H₁O.” No other A old house. The bottle was labelled information was given, but inside the bottle were some white crystals. The student took the bottle to a chemistry laboratory, where she analyzed the crystals with the help of the laboratory staff. C₁2H₁6O reacted with Br₂ in CCl4 adding one mole of Br, and forming C₁₂H₁OB2₂. When a sample of C₁₂H₂O was reacted with O3 followed by Zn/H₂O, two different samples, J and K, were obtained. Compound J had a molecular formula of C.HgO₂, and its NMR is shown below. Compound K had a molecular formula of C₂H₂O, and it could be oxidized to compound L, with a molecular formula of C₂H₂O₂. The IR spectrum of L showed a very wide, strong band centred around 3000 cm*¹. The NMR spectrum of L showed only two different absorptions: a doublet (6H) at 0.9 ppm and a septet (1H) at 3.6 ppm. There was also a singlet (1H) off the scale at 11.8 ppm. students, deduce possible…
