What technique would you use to separate the Drierite from the silicon? *

Filtration

Explanation:

Filtration is a separation technique used in the laboratories to separate two elements or compounds by using a filter paper and a beaker.

Drierite is also know as calcium sulphate and silicon is made up of silica.

The filtration equipment are taken to separate these two components. The separation method is used in the second beaker by pouring the mixture through a filtering funnel and using a filter paper. The solid remaining of silicon remains on the filter paper separating the two.

that's what i got you can count the number of atoms

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.
