1 Students perform several experiments recording the reactions in lab journals. The students write and balance the chemical equations for each reaction and include the state of matter notations for each compound. The equations are below. Equations from Experiments Experiment 1 MgO(s) + H2O(1) ► Mg(OH)2(aq) Experiment 2 4Fe(s) + 302(9) - 2Fe2O3(s) Experiment 3 SO3(g) + H2O(1) - H2SO4(aq) Which chemical involved in the student experiments is dissolved in water?

Which statement about the stamps is correct?

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

Can you me with this i really appreciate it
