Answer:
Oil has the smaller heat capacity. The effectiveness of the heat exchanger is 0.80.
Explanation:
Part 1:
In order to know which fluid has the smaller heat capacity we need to consider the heat equation below:
Q = CΔT, where Q is the heat exchanged, C is the heat capacity and ΔT is the variation in temperature.
As the heat exchange is the same for both fluids, the smaller the temperature variation, the smaller the heat capacity.
Water: ΔT = 120 °F
Oil: ΔT = 80 °F
Therefore, oil is the fluid with the smallest heat capacity.
Part 2:
The effectiveness of a counter-flow heat exchanger is given by the equation bellow:
Th1: initial temperature of the hot fluid
Th2: final temperature of the hot
Tc1: initial temperature of the cold fluid
Answer:
Explanation:
Slow but able to move past one another
<span>1.) Adding CO2 creates a stress on the equlibrium system.which means there will be exothermic reaction in other words more product (i:e H2CO3) will be formed.
</span><span>The equilibrium will shift to the right to offset the applied stress.
</span>
Hence more H2CO3 will be produced. Option A is correct.
2.) Rate = <span>[SO2]2 x [O2] / [SO3]2.
</span>
Hence option C is correct.
Hope this helps!
<span>Missing question: sulfanilamide has a solubility in 95% ethanol of </span>210 mg/ml<span> at 78 degree Celsius.
m(</span>sulfanilamide) = 0,75 g = 0,75 · 1000 = 750 mg.
210 mg : 1 ml = 750 mg : V(ethyl alcohol).
210 mg · V(ethyl alcohol) = 750 ml · mg.
V(ethyl alcohol) = 3,57 ml.
Answer is: 3,57 ml <span>of 95% ethyl alcohol will be required.</span>
