Draw the Lewis structure for each of the following and THEN determine the electron-pair geometry of the atom indicated. Do not include formal charges in your drawing. C in CS2 : electron-pair geometry

The electron pair geometry is linear

Explanation:

Carbon in carbon disulphide is surrounded by four electron pairs which is ordinarily expected to lead to a tetrahedral electron pair geometry according to Valence shell electron pair repulsion theory (VSEPR). However, the observed shape is linear due to the fact that double bonds cause more repulsion than single bonds. The double bonds force the molecule into a linear arrangement as in Carbon IV oxide molecule. See image attached for structures.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

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.
