In a bromine-producing plant, explain how many liters of gaseous element albromine at 300 degree Celsius and 0.855atm are formed by the reaction of 275g of sodium bromide and 175.6 g of sodium bromate in aqueous acid solution? Presume no Br2 dissolves
5NaBr (aq) + NaBrO3 (aq)+ 3 H2SO4(aq) ----> 3Br(g) + 3Na2SO4 (aq) +3H20(g)
A 0.291 mol sample of PCl5(g) is injected into an empty 4.35 L reaction vessel held at 250 °C. Calculate the concentrations of PCl5(g) and PCl3(g) at equilibrium.
The specific heat of lead is 0.0380cal/g degree celcius. If 47.0 calories of energy raised the temperature of a lead sample from 28.3 degrees celcius to 30.1 degrees celcius.
Can anyone help me with bromination and why it is more selective than chlorination. We have to use endo and exothermic graphs to explain
if 4.50g of methane gas is introduced into an evacuated 2.00 L container at 35 celcuis what is the pressure in the container?
What final temperature, in degrees celcius, is needed to change the volume of the gas to each of the following, if n and P do not change?
The high-field:low-field integration ration is 2:1. Deduce the structure of the organic hald and explain the NMR signals. I'm thinking it's 1,1-dichloropropane.
The incomplete pressures of CH4, N2, and O2 in a sample of gas were found to be 100, 450, and 200 mmHg, respectively. Compute the mole fraction of Nitrogen.
