There should be about 0.117 moles of oxygen in the original sample. Is this for the mastering chemistry online quiz? for universiy?
The percentage is 23,14 %.
it would be 16.97%
a, b, c or d
To identify an unknown sample by its emission spectrum
Cc = (D30)^2 / (D10 * D60) Where: * D60 is the particle-size diameter for which 60 percent of the sample was finer, and, * D30 is the particle-size diameter for which 30 percent of the sample was finer. * D10 is the particle-size diameter for which 10 percent of the sample was finer.

More collisions between particles of matter means a faster reaction rate. When you increase the kinetic energy of a sample of matter, you increase the number of particle collisions, as well as the force with which they collide. This in turn increase the rate of reaction.
The smallest particle of matter that retains the properties of the element of which it is a sample.
peptidoglycon chain
it is need so as a control.
the size of its largest particle
Answer each question
The smallest particle of matter that retains the properties of the element of which it is a sample.
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
