The Chemistry of Latent Fingerprints KEY Chemical Reaction Silver nitrate (AgNO3) can react with the salt (NaCl) left from the perspiration on the friction ridge skin to form solid silver chloride (AgCl) and sodium nitrate. The silver chloride can then be converted to silver oxide (Ag2O)‚ which is dark in color and can be more easily seen. Challenge Suppose the fingerprint processing technique that uses silver nitrate to react with the salt from perspiration produced 5.8 x 10-2 grams of silver

time of change. It was a time when blacks wanted equal rights. The 1960s called for peace and freedom. During the 1960s people started to dressed in more colorful clothes.

Excitation Contraction Coupling Process The sequence of events that converts action potentials in a muscle fiber to a contraction is know as excitation contraction coupling. In order for a skeletal muscle fiber to contract‚ it has to get a signal from the nervous system. The part of the nervous system that it gets a signal from is called a motor neuron. An electoral signal‚ called an action potential travels down the axon and to the axon terminal. At the end of the motor neuron are structures

While parenting and opportunity can play a part in committing crimes‚ according to the latent trait theory‚ the propensity for an individual
