Answer:


Explanation:
Hello,
In this case, we can compute the energy by using the following formula for air:

Whereas the moles of air are computed via the ideal gas equation at room temperature inside the 5.5m x 6.5m x 3.0m-room:

Now, we are able to compute heat, by considering that the temperature raise is given in degree Celsius or Kelvins as well:

Finally, we compute the time required for the heating by considering the heating rate and the required heat, shown below:

Answer:
(It's C)
Solid particles become evenly dispersed among liquid particles.
Explanation:
Just did the quiz on Edgenuity 2020
Reaction of Copper with Mercuric Nitrate is as follow,
Cu + Hg(NO₃)₂ → Cu(NO₃)₂ + Hg
According to equation,
1 Mole of Cu reacts to form = 1 Mole of Hg
So,
1.20 Moles of Cu will react to produce = X Moles of Hg
Solving for X,
X = (1.20 mol × 1 mol) ÷ 1 mol
X = 1.20 mol of Hg
Result:
1.20 mole of Cu when reacted with mercuric nitrate produces 1.20 moles of Hg.
