The shapes of molecules is determined by the number of electron pairs on the valence shell of the central atom in the molecule. These electron domains include lone pairs and bond pairs.

The lone pairs only contribute towards the electron domain geometry and not the molecular geometry. SCl4 has five electron domains hence its electron domain geometry is trigonal bipyramidal. The molecular geometry of the compound is seesaw.

The pressure system begins at 99.7 kpa.the volume of the gas is 150ml . What would be the final volume in the system if the pres

____ [38]

Assuming ideal behavior of the gas for a fixed amount when temperature is held constant, the pressure and volume are inversely proportional as given by the expression
P1V1 = P2V2
where the terms with subscripts of one represent the initial conditions for pressure and volume of the gas while for terms with subscripts of two represent the final conditions.
Rearranging the Boyle's law equation to calculate for the final volume V2:
V2 = P1V1 / P2
V2 = (99.7 kPa)(150 mL) / 99.8 kPa
V2 = 149.85 mL

What is the molarity of 245.0g of h2so4 dissolved in 350ml of solution

kirill115 [55]

M

350 mL = 0.350 L

245.0g H2SO4 / 98.08 g/mol H2SO4
= 2.5 mol H2SO4

2.5 mol H2SO4 / 0.350 L = 7.14 M
