When someone standing at one end of a large room opens a bottle of vinegar, it may take several minutes for a person at the other end to smell it. gas molecules at room temperature move at very high velocities, so what is responsible for the delay in detection of the vinegar?

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
