You find a 1979 copper penny (and note that pre-1982 pennies are pure copper) in the snow and pick it up. how much heat does the penny absorb as it warms from the temperature of the snow, −5.0∘c to the temperature of your body, 37∘c? assume the penny is pure copper and has a mass of 3.10 g. (the specific heat capacity of copper is 0.385 j/(g⋅∘

The penny absorbs 50 J.

q = mcΔT

ΔT = T_f – T_i = 37 °C – (-5.0 °C) = 42 °C

q = 3.10 g × 0.385 J·°C⁻¹g⁻¹ × 42 °C = 50 J

Note: The answer can have only two significant figures because that is all you gave for the temperature of your body.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
