Athermistor is a device that can measure temperature with great accuracy. the principle is simple; the resistance of a semiconductor is measured and the temperature is then estimated based on knowledge of the temperature dependence of the resistivity of the semiconductor. consider a thermistor which is made of a pure (intrinsic) semiconductor. at 0°c a resistance of 10,000 sn is measured. at 100°c, the resistance is 420 q. if the resistance is 2000 q at tı, what is tı? [hint: assume constant electron and hole mobility over the above temperature range] (а) 15°c (b) 43°c** (c) 82°c (d) 66°c

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

answer; i believe the correct answer is (solid gold);

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
