What is the total amount of heat released when 94.0 g water at 80.0 °C cools to form ice at −30.0 °C?
Wewaii [24]

Answer:

The total amount of heat released  is  68.7 kJ

Explanation:

Given that:

mass of water = 94.0 g

moles of water = 94 / 18.02 = 5.216

80⁰C   ------>  0⁰C  -------->    -30⁰C

Q1 = m Cp dT

      = 94 x 4.184 x (0 - 80)

     = -31463.68 J

     = -31.43 kJ

Q2 = 6.01 x 10^3 x 5.216

    = - 31348.16 J

   = -31.35 kJ

Q3 = - 94 x 2.09 x 30

    = - 5893.8 J

   = -5.894 kJ

Total heat = Q1 + Q2 + Q3  = -31.43 kJ  + (-31.35 kJ  ) + (-5.894 kJ )  = -68.7 kJ

Total heat released = -68.7 kJ

Note that the "negative sign" simply indicates heat released, therefore no need to put it in the answer.

Reference the following attachment

The number of molecules of gases in each of the 3 vessels is the same.

<h3>Number of moles</h3>

The first vessel contains 2g of H_2 gas:

Number of molecules in 2 g = 2/2 = 1 mole

The second vessel contains 32 g of O_2 gas:

Number of molecules = 32/32 = 1 mole

The third vessel contains 44 g of CO_2 gas:

Number of molecules = 44/44 = 1 mole

Thus, the 3 vessels contain the same number of moles of gases.

More on the number of moles can be found here: brainly.com/question/12513822
