Coffee cools more quickly in a ceramic mug than in a Styrofoam
cup.
Explanation:
Styrofoam is a good insulator, thus for keeping the coffee warm for longer, it is a good choice than ceramic. The process involved in the control of heat dissipation employs the fact that the vapours in the form of gas are entrapped within, they lessen the conduction process between the molecules as a result molecules do not collide hence no energy releases or exchange takes place.
Styrofoam cups are made up of polystyrene foam. As a result of high insulation at styrofoam body conduction is not possible so coffee is warmer for longer.
The balanced chemical reaction is expressed as:
<span>8SO2 + 16H2S = 3S8 + 16H2O
We are given the initial amount of the reactants. From there, we determine the limiting reactant. We do as follows:
87.0 g SO2 ( 1 mol / 64.07 g ) = 1.36 mol SO2 ( 16 mol H2S / 8 mol SO2 ) = 2.72 mol H2S
87.0 g H2S ( 1 mol / 34.08 g ) = 2.55 mol H2S ( 8 mol SO2 / 16 mol H2S ) = 1.28 mol SO2
Therefore, the limiting reactant would be H2S. We calculate the maximum amount of S8 that can be produced from the amount of H2S.
2.55 mol H2S ( 3 mol S8 / 16 mol H2S ) ( 256.48 g / 1 mol ) = 122.63 g S8</span>
4 atoms of Oxygen are required to make 2 atoms of hydrogen. The compound H2O is 1 Hydrogen and 2 Oxygen.
The answer is D 800 degrees Celsius
