<span>An element is a pure substance that cannot be broken down by further chemical techniques. Therefore you could try heating, cooling, electrolysis or other methods to see if it was an element or a compound.</span>
Yes the same set uo because
mass = grams
I believe that the answer for this question would be option A. 8 HOURS. Based on the given scenario above about a certain radioactive isotope placed near a Geiger counter, the half-life <span>of the isotope 32 hours later would be 8 hours. Hope this is the answer that you are looking for. </span>
Explanation:
As it is given that stream A is super heated. From stream tables, we get that specific enthalpy, (
) is 3054.29 kJ/kg.
For stream B, it is saturated water at 25 degree celsius. It's 
is 2546.54 kJ/kg.
Stream C, data will be as follows.
P = 200 kPa, 
= 0.9
So, 
= 
= 504.47 + 0.9 \times 2201.7
= 2486 kJ/kg
Now, energy balance formula will be as follows.
= 
= 
= 28.16 kg/s
Hence, inflow of saturated liquid is 28.16 kg/s. According to steam table, temperature of wet steam is 
Mass flow rate of out flow is 31.16 kg/s.
In a chemical reaction, the difference between the potential energy of the products and the potential energy of the reactants is equal to the heat of the reaction<span>. This is, the net energy released or absorbed (change) during a chemical reaction is the sum of the potential energy of the products less the sum of the potential energy of the reactants.</span>
