a) Write a balanced equation for the combustion of butane gas. b) If at a given moment butane is reacting at a rate of 0.400 mol L?1s?1, what are the rates of formation of products? c) What is the rate at which oxygen is reacting? I found the balanced equation, (2C4H10 + 13O2 --> 8CO2 + 10H2O) but I don't know how to get b and c from that
In the early days of the periodic table, the 1870s, both silicon and tin were known elements, but germanium was unknown. Using these trends and the densities of silicon and tin that you just obtained, estimate the density of germanium?
