A potential source of error for this lab could arise if not enough acid was added to the iron solution before the titration was started. This would allow much of the permanganate to go to MnO2 (s) rather than to Mn2 , leading to more permanganate needed for the titration. How would this affect the % of iron found at the end of the experiment

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
