3 Cu + 8HNO3 g 3 Cu(NO3)2 + 2 NO + 4 H2O
Ksivusya [100]

Considering the reaction stoichiometry, the amount of moles of NO that is produced when 27 moles of HNO₃ react is 6.75 moles.

<h3 /><h3>Reaction stoichiometry</h3>

The balanced reaction is:

3 Cu + 8 HNO₃ → 3 Cu(NO₃)₂ + 2 NO + 4 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:  

  • Cu: 3 moles
  • HNO₃: 8 moles
  • Cu(NO₃)₂: 3 moles
  • NO: 2 moles
  • H₂O: 4 moles

<h3>Amount of moles of NO produced</h3>

It is possible to determine the the amount of moles of NO produced by a rule of three: if by stoichiometry 8 moles of HNO₃ produce 2 moles of NO, if 27 moles of HNO₃ react how many moles of NO will be formed?

amount of moles of NO=\frac{27 moles of HNO_{3} x 2 moles of NO}{8 moles of HNO_{3}}

<u><em>amount of moles of NO= 6.75 moles</em></u>

In summary, the amount of moles of NO that is produced when 27 moles of HNO₃ react is 6.75 moles.

If a reaction produces 1.506 kJ of heat, which is trapped in 30.0 g of water initially at 26.5 C on a clorimetr liake hat in Fig
Dvinal [7]

<u>Answer:</u> The final temperature of water is 38.5°C

<u>Explanation:</u>

To calculate the amount of heat released or absorbed, we use the equation:

q=mc\Delta T

where,

q = heat absorbed = 1.506 kJ = 1506 J   (Conversion factor: 1 kJ = 1000 J)

m = mass of water = 30 g

c = specific heat capacity of water = 4.184 Jl/g.°C

\Delta T = change in temperature = T_2-T_1=T_2-26.5^oC

Putting values in above equation, we get:

1506J=30g\times 4.184J/g.^oC\times (T_2-26.5^oC)\\\\T_2=38.5^oC

Hence, the final temperature of water is 38.5°C
