Explain what mass of glycerin (C3H8O3) a non-electrolyte must be dissolved in 200.0g water to give a solution with a freezing point of -1.50 degrees Celsius.
Write the cell reaction for the combination of these half-cell reactions that leads to the largest positive cell emf
A voltaic cell consists of a Mn/Mn2+ electrode (E° = -1.18 V) and a Fe/Fe2+ electrode (E° = -0.44 V). Calculate [Fe2+] if [Mn2+] = 0.050 M and Ecell = 0.78 V at 25°C.
Calculate the molar kinetic energy (in joules per mole) of a sample of Ne(g) at (a) 25.00 degree C and (b) 26.00 degree C
a steel reaction vessel has a movable piston that is set to allow an enclosed sample of gas expandnbspand contract
When a solution of hydrogen peroxide is put on a cut, it bubbles, producing water and oxygen gas. If someone puts 0.56 mL of 3.00% hydrogen peroxide solution on a cut, what is the volume in mL of oxygen produced
The formula thionyl chloride is SOCL2. This compound is a very powerful drying agent in the synthetic chemistry industry as it reacts completely with water according to the following unbalanced equation
The balanced chemical reaction for the titration performed in this lab demonstration is: NaCOOH(aq)+NaOH(aq)=Na(CH3COO)(aq)+H2O(l). A basic solution has positive ions and OH- ions like Na+ and OH-.
2NOCl(g) → 2NO(g) + Cl2(g) ,At 450 K the rate constant is 15.4 atm-1s-1. How much time (in s) is needed for NOCl originally at a partial pressure of 46 torr to decay to 25.8 torr.
The volume of solution B remains constant which is 10mL. The different concentration of Solution A determines the rate of reaction. However now I want to ask. Explain why is it important to keep the total volume of the solution in 10mL
