What mass of Na2CO3, in grams is required to completely react with 50 ml of 0.125 m HNO3 balance the equation: NaCO3(aq)+HNO3(aq) -->NaNO3(aq)+CO2(g)+H2O(l)
They are tethered together and are at the same temperature and pressure. Which balloon has the greater number of gas particles? Which balloon has the greater mass? Which balloon has the greater density?
However, 1,2-dichlorobutane was more than twice as present in the products as 1,3-dichlorobutane. Account for the differencees between the two.
what pressure would it exert? (b) What pressure would it exert if it behaved as a van der Waals gas?
What is the power output of the turbine? H1= 1322.6 Btu/lbm v1=3.058 (ft)^3/lbm H2= 1148.6 Btu/lbm v2=78.14 (ft)^3/lbm
An open flask sitting in a lab fridge looks empty, but we know that actually it is filled with a mixture of gases called air.
the slopes corresponding to standard Beer's Law plots were as follows: ?IA = 0.072 ?IB = 0.306 ?IIA = 0.760 ?IIB = 0.036 Using this data, calculate the ratio between the relative concentrations of MR- and HMR in this solution.
