C2O42– + MnO2 Mn2+ + 2 CO2 As a result of the above reaction, the oxidation number of each C atom is

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.

Which statement describes the phase change that occurs when dry ice is placed in an open container at room temperature?

If 16.00g of hydrogen gas reacts with 126.73g of oxygen, how many grams of water are yielded? (both reactants are completely consumed in the reaction.)
