How many au atoms are there in 1.00kg (5.08 mol) of gold?

What is the temperature of one mole of helium gas at stp?

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

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