In 1874, dutch chemist jacobus van’t hoff (1852–1911) and french chemist joseph le bel (1847–1930) independently deduced that a carbon atom bonded to four atoms assumes a tetrahedral geometry. prior to that time, it was believed that tetravalent carbons assumed a square planar geometry. one piece of evidence that can be used to support a tetrahedral geometry is the fact that molecules with the general formula cx2y2 (where x and y are either a hydrogen or a halogen atom) are always polar. explain how this supports a tetrahedral geometry and rules out a square planar geometry.

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
