A dull grey metallic looking substance which weighed 3.6 g was burned in air completely to produce 13.2 g of a gas with the following properties. It quinched a burning flame, and it was heavier than air g it would sink down to the bottom of a container it was also found that the same quantity of mass of oxygen (O2) Consumed by burning the 3.6 g of substance if combined with exactly 12 grams of hydrogen gas, produced 10.8g of water.
What was the mass(g) of molecular oxygen from the air that combined with the substance to produce the dense gas?
What is the ratio of the weight of oxygen burned to the weight of the dense gas produced?
Given the molecular mass of the water h2o is 18amu per molecule g or g mole what is the molecular mass of the dense gas?
What is the molar composition of the dense gas and it's chemical formula?
What is the element name and identity and atomic mass of the grey substance
In a gas mixture, the partial pressures are nitrogen 435 , oxygen 145 , and helium 240 . What is the total pressure ( torr) exerted by the gas mixture?
Determine the pH of the acid solution before the titration begins and the pH at the equivalence point when 50.0 mL of the NaOH has been added. The Ka of HF is 7.2*10^-4
What is the molarity of a solution of 14.0 g NH4Br in enough H2O to make 150 mL of solution?
If someone can go in depth into finding the Ka to this and then guiding me through the rest of the steps, I'd be eternally grateful
