When observing the effect of surface area on the rate of a heterogeneous reaction, it is common to observe that the mossy zinc is reacting much faster than the zinc granules (at least at the onset of the initial reaction). This is exactly the opposite what should be observed for this reaction. What would cause the zinc powder to react more slowly than the mossy zinc?

Which compound contains both ionic and covalent bonds? a) hbr b)cbr4 c)nabr d) naoh

What type of reaction fuels the processes seen here?

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.
