Using the equation below, if the rate of disappearance of Cl2 is 0.26 M/min, what is the rate of this reaction? 2NO(g) + Cl2(g) → 2NOCI(g)

A 45.0 mL solution containing a mixture of 0.0634 M KCN and 0.0634 M KCI is titrated with 0.107 M AgNO. From this mixture, which silver salt will precipitate first? A list of Ksp values can be found in the table of solubility constants. • AgCI • not enough information to determine AgCN What is the concentration of Ag* at the first equivalence point? [Ag*] = Will the second silver salt begin to precipitate at the first equivalence point before the first silver salt has completely precipitated? • not enough information to determine • yes • no

Need help understanding please help  Let’s assume the initial volume of the gas is  4.80 LL   , the initial temperature of the gas is   29.0 °C°C   , and the system is in equilibrium with an external pressure of 1.2 bar (given by the sum of a 1 bar atmospheric pressure and a 0.2 bar pressure due to a brick that rests on top of the piston). What is the final pressure of the gas? What is the final volume of the gas? What happens with the piston after you finish heating the gas? Assume you do not need to worry about the gas cooling down again because the outside of the container is at a lower temperature. That is, you manage to keep the gas at a constant temperature that equals  54.2 °C°C    What is the sign of w? What is the value of w? Be careful with units. How do you convert bar*L to J?
