What is the mass of 8.00 × 10 22 molecules of nh 3?

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

i believe that it is a exoplanet

the dependant variable is spilled water

the independent is the heat

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
