The decomposition of copper(ii) nitrate on heating is endothermic reaction. 2cu(no3)2(s) → 2c10(s) + 4no2(g) + o2(g) calculate the enthalpy change for this reaction using the following enthalpy changes of formation. ah! [cu(no3)2) = -302.9 kj mol? ah, (cuo) = -157.3 kj mol? . ah[no2) = +33.2 kj mol.

Calculate the change in entropy if br2(l) is converted into gaseous br atoms. s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

What must happen before a body cell can begin mitotic cell division

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
