Orbitals are space around the nucleus where electrons orbit. Several orbitals can exist in a given energy level/shell. Carbon is the sixth element of the periodic table with 6 electrons. Carbon atoms have the ability to bond to themselves and to other atoms with sp, sp² and sp³, hybrid orbitals. Several orbitals in carbon are spherical conformation and this accounts to about 40% of the orbitals.
Answer:
a warm air mass is caught between two colder air masses. The colder air moves under the warmer air pushing it up and then moves forward until it meets a mass that is warmer and pushes it up too.
Answer:
c iodine
Explanation:
fluorine is a halogen group element like Bromine, Iodine,Astatine,Chloride
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:In the chemical formula Al2(SO4)3, the Al2 means there two aluminium (atoms or ions). The SO4 is a sulfate ion and (SO4)3 means there are 3 sulfate ions. The number 3 before Al2(SO4)3 means there are three times the number of atoms and ions of the chemical formula.
