How many moles of argon are in 30.6L at 28K and 658 mmHg?
lesantik [10]

Answer : The number of moles of argon gas is, 11.5 mol

Explanation :

To calculate the moles of argon we are using ideal gas equation as:

PV=nRT

where,

P = pressure of argon gas = 658 mmHg = 0.866 atm    (1 atm = 760 mmHg)

V = volume of argon gas = 30.6 L

n = number of moles of argon gas = ?

R = gas constant = 0.0821 L.atm/mol.K

T = temperature of argon gas = 28 K

Now put all the given values in the above formula, we get:

(0.866atm)\times (30.6L)=n\times (0.0821 L.atm/mol.K)\times (28K)

n=11.5mol

Therefore, the number of moles of argon gas is, 11.5 mol

What are the three end products of the oxidation-reduction reactions involved in metabolism?
san4es73 [151]
Answer: The three end products of the oxidation-reduction reactions involved in metabolism are WATER, CARBON DIOXIDE and ATP.

Metabolism refers to the sum of all chemical reactions occurring in the body. It includes both catabolism and anabolism. Every metabolic reaction is characterized by oxidation-reduction reactions. The metabolic pathways include respiration, photosynthesis, etc. In all these reactions water is produced. In respiration CO2 is also a product. In general. in every metabolic reaction either an organic molecule is broken or synthesized producing CO2, water and energy.
