A 0.0372-m3 container is initially evacuated. Then, 4.65 g of water is placed in the container, and, after some time, all of the
Montano1993 [528]

Answer:

18.3 kilopascals

Explanation:

We are given that the volume of this container is 0.0372 meters^3, that the mass of water is 4.65 grams, and that the temperature of this water vapor ( over time ) is 368 degrees Kelvins. This is a problem where the ideal gas law is an " ideal " application.

_______________________________________________________

First calculate the number of moles present in the water ( H2O ). Water has a mass of 18, so it should be that n, in the ideal gas law - PV = nRT, is equal to 4 / 18. It is the amount of the substance.

We now have enough information to solve for P in PV = nRT,

P( 0.0372 ) = 4 / 18( 8.314 )( 368 ),

P ≈ 18,276.9

Pressure ≈ 18.3 kilopascals

A chemical change in which a single compound is broken down into two or more simpler products.
andreyandreev [35.5K]

Answer:

Decomposition or cracking

Explanation:

Decomposition reaction is a chemical change in which a single compound is broken down into two or more simpler products.

  For example;

                   A     →    B   +  C

 The driving force of such reaction is the high positive heat of formation of the compound which indicates that they are highly unstable.

Some stable compounds also decompose when subjected to high temperature and pressure.
