A student needs to prepare 50.0 mL of a 0.90 M aqueous H2O2 solution. Calculate the volume of 4.9 M H2O2 stock solution that should be used to prepare the solution.

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

What happens to isotopes that are unstable?

Pl what kind of reaction is this? nahco3 + h2o → co2 + naoh + h2o -composition -decomposition -single replacement -double replacement im leaning more toward single replacement. if im wrong can you explain whyy?
