In Rutherford's famous experiment, he shot heavy, fast moving, positive alpha particles at a thin gold foil. Based on Thomson's plum pudding model of the atom, what did Rutherford expect to happen, and why?

At a temperature of 393 k, the temperature of a sample of nitrogen is 1.07 atm what will the pressure be at a temperature of 478 k

What is the most important factor in determining climates.

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
