A45.30 g sample of solid mercury is initially at –59.00°c. if the sample is heated at constant pressure ( = 1 atm), kj of heat are needed to raise the temperature of the sample to 30.00°c.

0.165kJ

Explanation:

Formula to use for such a question is;

Energy = number of mole x molar gas constant x change in temperature

Number of mole = reacting mass of mercury / molar mass of mercury = 45.30/200.58 = 0.226moles

Change in temperature = final temperature - initial temperature = 30 - (-59) =30 + 59 = 89 Kelvin

E = nRT = 0.226 x 8.314 x 89

Energy = 165.35Joules

Energy in kJ = 165.35/1000 = 0.165kJ

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
