Describe the best method for separating a mixture of sand, salt, and steel shavings by placing the steps below in the correct order. heat the mixture to evaporate the water. pour the mixture through a filter to separate the sand. pass a magnet over the mixture to remove the steel. add water to the sand/salt mixture and stir to dissolve the salt.

The following is the correct order in which the mixture of sand, salt and steel can be separated:  

1. Pass a magnet over the mixture to remove the steel.  

2. Add the water to the sand/salt mixture and stir to dissolve the salt.  

3. Heat the mixture to evaporate the water.  

4. Then finally pour the mixture through a filter to separate the sand.  

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.
