2.0 L HC2H3O2 (acetic acid) is made by diluting 75. mL of 17.6M acetic acid. What is the molarity of the new solution ?

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.

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

What is the percent by mass of oxygen in fe2o3
