Answer:
Hydrogen and Helium are the main components of the sun.
Explanation:
In simple terms a force is what makes anything do move or stay still. Some forces are contact forces and some are non contact. Hope this helps.
Answer:
22.01J/Kmol
Explanation:
The parameters given in this question are;
Enthalpy (H) = 6.01 kJ/mol.
Number of moles = 1
Entropy change (S) = ?
The formular relationship between entropy and enthalpy is given as;
ΔS=ΔH/T
Temperature for water at freezing point = 0C + 273 = 273 K (converting to Kelvin)
ΔS = 6.01/273
ΔS = 0.0220kJ/Kmol
ΔS = 0.02201 * 1000 = 22.01J/Kmol

Amino acids have a common structure where there is a carboxyl group at one end (CO2H) and a amino group at the other (NH2). There's also a side chain that's unique for every amino acid. When two amino acids are joined in producing a polypeptide, the carboxyl and amino groups are linked with the release of a water molecule.
So in this problem, you simply need to count the number of links, which will be 1 less than the number of amino acids in the chain. Hence, for a 14 amino acid chain, you need 13 links which produced 13 water molecules.</span>
