A student holds a 95.33g piece of copper metal in the flame of a Bunsen burner for 5 minutes . After cooling, the student records mass of the metal as 119.33g. What mass of oxygen gas must have reacted with the copper metal? Pls write the chemical equation

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

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
