[SCN][HC2O4]SNF3 [S2CO]2[IO3][HCO3]PF3 [SO4]2[C3H5]+ [S3N3]- (cyclic, every other atom is S) [ClO4](C is central) Page 1 of 1 Worksheet for Lewis Structures, Resonance Structures, and Formal Charge Solutions 1.) S C N S C N There are two things to consider here. The structure on the left gives N three bonds which is good, the structure on the right puts the formal negative charge on the more electronegative element.

Gravitational potential energy of an object (Ep) of mass m at a height of h above the Earth’s surface, is defined as Ep=mgh. It can therefore be summarised that for an object to accumulate gravitational potential energy, work/energy must be exerted on it. * Define gravitational potential energy as the work done to move an object from a very large distance away to a point in a gravitational field Ep = -Gm1m2r * As stated before, gravitational potential energy is defined as the energy of a mass due to its position within a gravitational field. It can also be defined, however, that the force of attraction between a planet and an object (gravitation) will become zero at an infant distance away from the planet. We can therefore define
A 4.0-μC charge is located 0.30 m to the left of a +6.0-μC charge. What is the magnitude and direction of the electrostatic force on the positive
We can conclude that the data are Poisson distributed. Chi-Square test of independence Problem 12.12 Use the following contingency table to determine whether variable 1 is independent of variable 2. Let α = .01 | Variable 2 | Variable1 | 24 | 13 | 47 | 58 | | 93 | 59 | 187 | 244 | Step 1 Ho: the two classifications are independent Ha: the two classifications are dependent Step 2 d.f = (r – 1) (c – 1) Step 3 α = 0.01 x 2 0.01, 3df = 11.3449 Step 4 Reject Ho if x 2 > 11.3449 | Variable 2 | Total | Variable1 | 24 (22.92) | 13 (14.10) | 47 (45.83) | 58 (59.15) | 142 | | 93 (94.08) | 59 (57.90) | 187 (188.17) | 244 (242.85) | 583
