Which of the diethylbenzene isomers (ortho, meta, or para) corresponds to each set of 13c nmr spectral data? [a] 13c nmr signals: 16, 29, 125, 127.5, 128.4, and 144 ppm [b] 13c nmr signals: 16, 29, 128, and 141 ppm [c] 13c nmr signals: 15, 26, 126, 128, and 142 ppm

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
