If 20.6 grams of ice at zero degrees Celsius completely change into liquid water at zero degrees Celsius, the enthalpy of phase change will be positive. TRUE FALSE

TRUE.

Explanation:

Hello,

In this case, since the fusion enthalpy of ice is +333.9 J/g and the fusion entropy is defined as:

We can compute it considering the temperature (0 °C) in kelvins:

Therefore answer is TRUE.

Best regards.

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.
