A quantity of 4.00 102 mL of 0.600 M HNO3 is mixed with 4.00 102 mL of 0.300 M Ba(OH)2 in a constant-pressure calorimeter of negligible heat capacity. The initial temperature of both solutions is the same at 18.76°C. What is the final temperature of the solution?
What is the probability of locating an electron between x = 0 and x = 0.2 nm in its lowest energy state in a conjugated polyene molecule
2A(g) + 3B(g) → A2B3(g) If 0.5 atm of gas A is mixed in an evacuated reaction flask with 1.0 atm of gas B, what is the final pressure in the reaction flask? (assume that the reaction goes to completion)

Calculate the volume (in mL) of He collected at STP when 3.60 g of pure 226Ra is stored in a closed container for 135 years.
Can you please explain the molecular bonding of hydrocortisone. How many functional groups and what are they? I need the explanation of the actual chemical structure
A buffered solution is made by adding 50.9 g NH4Cl to 1.00 L of a 0.75 M solution of NH3. Calculate the pH of the final solution. (Assume no volume change.)
Suppose 1.00 g of water (saturated liquid) evaporates isobarically at atmospheric pressure of 1.013x10^5 Pa. Its volume in the liquid state is 1.00 cm3 and its volume in the vapour state is 1671 cm3.
