Explanation:
The van der Waals' forces are the forces that exist between the millions of separate water molecules, and not between the hydrogen and oxygen atoms in the case of water. Dipole-Dipole forces are one of van der Waals' three forces. ... For example, HCl comprised of the atom Hydrogen and Chlorine is polar.
Answer:
The answer to your question is: 82.9 %
Explanation:
Data
H2 = 42.6 g
NH3 = 200 g
percent yield = ?
Reaction
3H2 + N2 ⇒ 2NH3
Process
6 g of H --------------- 34 g of N
42.6 g ------------- x
x = 241.4 g of NH3
percent yield = 200 / 241.4 x 100
= 82.9 %
B) Recyclers of energy, as they decompose matter and turn it into energy that can be passed on to other organisms who eat the fungi
Explanation:
According to the heat relationship,
Heat given by steam = heat taken by water
Hence, 
= 
where, 
= specific heat
Value of 
at 250^{o}C and 12.5 atm is 2.326 
.
And, at 200^{o}C and 12.5 atm is 2.743 .
Therefore, average = 
= 2.5345 kJ/Kg^{o}C
As the given data is as follows.
= 400 kg/hr, 
= 
= 
, 
= 500 kg/hr
= 4.186 
Hence, putting the given values into the above formula as follows.
=
= 
As we know that, 
Thus, we can conclude that the new temperature of water is 
.
