A solid sphere of radius 40.0 cm has a total positive charge of 26.0 C uniformly distributed throughout its volume. Calculate the magnitude of the electric field (a) 0 cm, (b) 10.0 cm, (c) 40.0 cm, and (d) 60.0 cm from the center of the sphere

An electron is at rest just above the surface of a sphere with a radius of 2.6 and a uniformly distributed positive charge of 2.2 10 15 . Like a rocket blasting off from the Earth, the electron is given an initial speed radially outward from the sphere.

Reaction 1 CH4 + 2 O2 --> CO2 + 2 H2O Is the reaction exergonic or endergonic? Is the reaction spontaneous? Is the reaction anabolic or catabolic? Is Delta G positive or negative?

In a particular experiment, equal moles of H2(g) at 1.00 atm and Br2(g) at 1.00 atm were mixed in a 1.00 L flask at 25 C and allowed to reach equilibrium. Then the molecules of H2 at equilibrium were counted using a very sensitive technique, and 1.10 1013 molecules were found. For this...

Two identical positive charges exert a repulsive force of 7.0 10-9 N when separated by a distance of 3.0 10-10 m. Calculate the charge of each.

What minimum (positive) amount of energy must be supplied to cause these two atoms to separate?
