1. Aluminum has a specific heat of 0.902J/(g ∙ K) , how much heat is lost when a piece of aluminum with a mass of 28.372 g cools from a temperature of 429°C to 22.0°C. 2. A 500 g piece of iron (CP = 25.09 J/(mol · °C) changes 7°C when heat is added. How much heat energy produced this change in temperature?
3.When 300. cal of energy is lost from a 125 g object, the temperature decreases from 45.0°C to 40.0°C. What is the specific heat of this object?

58750.08068 is the answer i think

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
