Acompound is isolated from the rind of lemons that is found to be 88.14% carbon and 11.86% hydrogen by mass. 120.0 grams of said compound. what is the empirical formula?

CH2

Explanation:

Divide their percentages respectively by their atomic masses, take the least significant value to divide others. Eg

C has 88.14% an atomic mass of 12g/mol,

Hydrogen has 11.86% with atomic mass of 1g/mol.

C =88.14/12=7.345

H=11.86/1=11.86

Dividing through by the least number

C=7.345/7.345=1

H=11.86/7.345=2

Empirical formula therefore is CH2

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
