Answer: 19kpa
Explanation:
The total pressure of a mixture of gases is the sum of the partial pressure exacted by the individual gases.
P total = P X + P Y
From the question above:
P total = P .nitrogen + P. oxygen
123.5kpa = 104.5kpa + P. Oxygen
P. Oxygen = 123.5kpa - 104.5kpa
= 19kpa
Explanation:
Moles of N2 = 35.0g / (28g/mol) = 1.25mol
Moles of H2 = 60.0g / (2g/mol) = 30.0mol
Since 1.25mol * 3 < 30.0mol, nitrogen is limiting.
Moles of NH3 = 1.25mol * 2 = 2.50mol.
Mass of NH3 = 2.50mol * (17g/mol) = 42.5g.
30.0mol - 1.25mol * 3 = 26.25mol.
Excess mass of H2
= 26.25mol * (2g/mol) = 52.5g.
Answer: Anabolism
Explanation:
Chemical reactions that combine simple molecules and monomers to form complex structures are known as ANABOLISM.
Anabolic reactions which are also called biosynthesis reaction is a type of metabolic reaction in the body that forms larger molecules through combination of smaller molecules with the use of energy in the form of ATP molecules. Example if anabolic reactions in the body includes:
- formation of polysaccharide from monosaccharides,
- formation of triglycerides from fatty acids,
- formation of nucleic acids from nucleotides and many among others. I hope this helps, thanks.
A) The triple point
The triple point of a system is the thermodynamic point where the pressure, composition and temperature are maintained at a specific value and all three phases of that substance, solid, liquid and gas, coexist. This equilibrium is disturbed if any of the above mentioned variables are changed. The degree of freedom at the triple point is described as being zero.
