Asubstance has a triple point at -24.5 ∘c and 225 mmhg. what is most likely to happen to a solid sample of the substance as it is warmed from -35 ∘c to 0 ∘c at a pressure of 220 mmhg? a substance has a triple point at -24.5 and 225 . what is most likely to happen to a solid sample of the substance as it is warmed from -35 to 0 at a pressure of 220 ? the solid will melt into a liquid, the solid will sublime into a gas, or nothing (the solid will remain as a solid).

The solid will sublime into a gas

Explanation:

See the phase diagram attached (the diagram is not an exact representation of this case, it is only illustrative). You starts at point A, that is, a point below triple point pressure (220 mmHg is lower than 225 mmHg) and to the left of triple point temperature (-35 °C is lower than -24.5 °C). Then, you move to point B, which is at the same pressure at A but its temperature is to the right of triple point temperature (0°C is greater than -24.5 °C).

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
