Calculate the enthalpy of reaction for the combustion of methane gas, CH4 to form CO2(g) + H20(l)
If the density of the solution is 1.1094 g/mL, what is the molarity of the sulfuric acid?
dry ice solid co2 has a vapor pressure of 1 atm at -77.2 deg celsius and 2 atm at -69.1 deg celsius. calculate molar
if the molarity of the HCl solution was actually greater then the lable indicated would it affect the calculated value for the number of moles of HCl that reacted.
What is the molar solubility of barium fluoride (BaF2) in water? The solubility-product constant for BaF2 is 1.7 x 10^-6 at 25 °C
Window glass is typically made by mixing soda ash (Na2CO3), limestone (CaCO3), and silica sand (SiO2) and then heating to 1500 degrees Celcius to drive off Co2 from the Na2CO3 and CaCO3
Given that we start with 0.036M NO(g) and 0.036M O2(g) AND end with 0.014M NO2, what is the equilibrium constant for this reaction and what are the equilibrium concentrations for NO and O2?
Does solubility change with pH? If yes, what is the highest solubility for the following. ( pH=7, pH=6, pH=4) (In other words are the following compounds more soluble in neutral, basic or acidic solutions?) a) NaBr b) Ca(OH)2 c) CaBr2
A ball is thrown horizontally from the top of a building 19.0 m high and lands 63.7 m from base of the building.
