Answer:
oxygen and Hydrogen
Explanation:
Oxygen and Hydrogen causes rusting on metals after combining with moisture
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.
Answer: -
¹⁰B
Explanation: -
For ⁹Be,
The atomic number is 4.
The Mass number is 9.
The number of neutrons = mass number - atomic number
= 9 - 4 = 5
For ⁹B,
The atomic number is 5.
The Mass number is 9.
The number of neutrons = mass number - atomic number
= 9-5 = 4
For ¹⁰B,
The atomic number is 5.
The Mass number is 10.
The number of neutrons = mass number - atomic number
= 10-5 = 5
For ¹⁰Be,
TThe atomic number is 4.
The Mass number is 10.
The number of neutrons = mass number - atomic number
= 10-4 = 6
For ¹²C,
The atomic number is 6.
The Mass number is 12.
The number of neutrons = mass number - atomic number
= 12-6 = 6
The land is warm during the day. For example, if you near a sea early in the morning, you could see how cold, cool the place is.
