Answer:
Ammonia, urea, uric acid
Explanation:
The given compounds are:-
Urea which has a molecular formula of 
and has 2 atoms of nitrogen per molecule.
Ammonia which has a molecular formula of 
and has 1 atom of nitrogen per molecule.
Uric acid which has a molecular formula of 
and has 4 atoms of nitrogen per molecule.
Thus,
The order from least to most nitrogen is:-
Ammonia, urea, uric acid
About 6.5x10^22 molecules.
(5g C2H5OH)x(1 mol C2H5OH/46g C2H5OH)x(6.02x10^23 molecules C2H5OH/1 mol C2H5OH)=(3.01E24)/46=6.5x10^22.
Let me know if this helped!
It would be known as a meth_(insert - ane, - ene, and -yne) hydrocarbon.
1 bond = -ane
2 bonds = - ene
And so on.
The best phrase to complete the sentence is "single bonds". <span>A hydrocarbon molecule is considered to be saturated when the molecule contains single bonds. </span><span>Alkanes are a saturated type of hydrocarbon. They only
consists of hydrogen and carbon atoms in single bonds. The general formula is
CnH2n+2. </span><span>C4H10 is the molecular formula for butane. It is an example of a saturated hydrocarbon.</span>
