Which statement is true for flame ionization detectors (FID)? a. FID employs a beta emitter to ionize the sample.
b. The detector responds by combusting hydrogen gas from the mobile phase.
c. Emmision spectra are used to quantify the peak concentration
d. The FID flame gets cooler in the presence of hydrocarbon eluent.
e. FID relies on the combustion of the sample carbon atoms which produce CH radicals, CHO+ions, and electrons which are then detected.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.

Need ! asap will mark 10 pts using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers

Draw a line graph showing the relationship between temperature in kelvin as a function of kinetic energy.
