Question- A mixture of gases is prepared for laboratory experiments by combining 5.0 L of oxygen, 0.68 L of nitrogen, and 0.34 L of carbon dioxide. Determine the percentage of nitrogen in the mixture
This is not a problem given in the book, so I just need the full solution of deriving!
A calorimeter contains 27.0 mL of water at 11.0 C. When 2.10 g of X (a substance with a molar mass of 74.0 g/mol) is added, it dissolves via the reaction X{(s)}+H_2O{(l)} -> X{(aq)}
A sample of Tl-201 has an initial decay rate of 5.88 x 10 to the 4 seconds. How long will it take for the decay rate to fall to 55/s? (Tl-201 has a half-life of 3.042 days).
the partial pressure of co2 gas about the liquid in a carbonated drink is 6.2. assuming that the henrys law constant

Explain concisely why carbon has two electrons in different p orbitals with parallel spins rather than other possible arrangements.
In the unbalanced redox reaction below draw arrows which are in black bold as well as write the subsequent abbreviations "O" for oxidized atom, "R" for reduced atom, "OA" for atom that serves as the oxidizing agent as well as "RA" for the atom tha..
Compute the work that must be done against the atmosphere for the expansion of the gaseous products in the combustion of 1.00 mol C6H6 (l) at 25 degrees Celsius and 1.00 bar.

Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the C^14 has decayed to 1/16.0 of the original amount. How long ago was this plant alive. Express your answer numerically in years.
For half life problems how would you solve this. How old is a bottle of wine if the tritium (h-3) activity is 25% that of the new wine (h-3 half life =12.3 years)?
