Answer:
Explanation:
Hello,
In this case, we consider the reaction:
For which the law of mass action is expressed as:
Whereas the exponents are referred to the stoichiometric coefficients in the chemical reaction. Moreover, in table A-28 (Cengel's thermodynamics) the natural logarithm of the undergoing reaction at 2600 K is 2.801, thus:
In such a way, in terms of the change 
the equilibrium goes:
Hence, solving for :
Thus, the moles at equilibrium:
Finally the compositions:
Best regards.
Answer:
The barrel with the sharp edge will drain faster.
Explanation:
The barrel with filed down entrance will gradually allow water to flow out due to the soft round corner.
However, the barrel with sharp edge will create turbulent eddies because of the sudden contraction phenomenon at the exit point. This turbulent eddies will occur in the inside portion of the sharp edge. First, let us understand what Eddies are.
An eddy, is fluid current whose flow direction differs from that of the general flow. Eddies can transfer much more energy and dissolved matter within the fluid and they actually mix together large masses of fluid. They generally become more numerous as the fluid flow velocity increases.
Based on the above definition, we can see that due to the sharp edge created, the flow direction differs from that of the general flow thereby creating eddies that are usually turbulent which causes more outflow of water than that with the soft edge.
Answer:
208 mg/L
Explanation:
Only Mg++ and Ca++ causes hardness not Na+
Given
Mg++ = 20 mg/L
Ca++ = 50 mg/L
= 
= 208.33 mg/L 
208mg/L
