Standard State

When finding the standard enthalpy of an equation, how can you make sure that everything is in standard state?

It will usually be stated in the problem, otherwise you can look at the units. The standard state of substance is its phase (solid, liquid, gas) at 25.0 °C and one atmosphere pressure

for the elements, you can look at the periodic table. usually it says what state each element is in at 25 degrees celsius and 1 atm.
