On your paper draw the Lewis structure for CO12 and answer ALL the following questions: 1) Are there single bonds, multiple bonds, OR both? 2) Which atom is
the central atom? 3) How many electron groups are present on the central atom?
4) How many lone pair groups are present on the central atom? 5) What is the
name of the molecular shape?

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

In the cathode ray tube experiment, j. j. thomson passed an electric current through different gases inside a cathode ray tube in the presence of an electric field. in which two ways did this experiment change scientists’ understanding of the atom?

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
