Determine the heat of reaction (δhrxn) for the reaction of calcium carbonate (caco3) with hcl to produce co2 by using heat of formation data:

caco3 (s) + 2 hcl (g) → cacl2 (s) + co2 (g) + h2o (g)

The heat of reaction (ΔHrxn) for the reaction is -164.9kJ

Explanation:

The given balanced chemical reaction is,

To calculate the enthalpy of reaction .

where,

Putting values in above equation, we get:

Therefore the heat of reaction (ΔHrxn) for the reaction is -164.9kJ

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
