Which element is closely associated with the field of organic chemistry?
slega [8]

Answer:

Carbon

Explanation:

The field of organic chemistry is the field  of the study of the compounds of carbon mostly with hydrogen but they  can contain the presence of other atoms such as oxygen, nitrogen, sulfur even metals such as lithium. It studies the structure, properties, synthesis and reactions of these compounds. The field of organic chemistry is the field of living organisms as they are mostly are formed by organic compounds hence its name organic.

A non-mechanical, rigid, and fully insulated mixing tank is used to combine two inflows to produce wet steam. One inflow consist
Bogdan [553]

Explanation:

As it is given that stream A is super heated. From stream tables, we get that specific enthalpy, (h_{A}) is 3054.29 kJ/kg.

For stream B, it is saturated water at 25 degree celsius. It's h_{B} is 2546.54 kJ/kg.

Stream C, data will be as follows.

                P = 200 kPa,         \chi = 0.9

So, h_{c} = h_{f} + \chi \times h_{fg}  

        = 504.47 + 0.9 \times 2201.7

        = 2486 kJ/kg

Now, energy balance formula will be as follows.

            m_{A}h_{A} + m_{B}h_{B} = (m_{A} + m_{B})h_{c}

              3 \times 3054.29 + m_{B} \times 2546.54 = (3 + m_{B}) \times 2486

             m_{B} = 28.16 kg/s

Hence, inflow of saturated liquid is 28.16 kg/s. According to steam table, temperature of wet steam is 120.23^{o}C

Mass flow rate of out flow is 31.16 kg/s.
