In 1897 the swedish explorer andree tried to reach the north pole in a balloon. the balloon was filled with hydrogen gas. the hydrogen gas was prepared from iron splints and diluted sulfuric acid. the reaction is given below. fe(s) + h2so4(aq) feso4(aq) + h2(g)the volume of the balloon was 4870 m3 and the loss of hydrogen gas during filling was estimated at 20.%. what mass of iron splints and 95% (by mass) h2so4 were needed to ensure the complete filling of the balloon? assume a temperature of 0°c, a pressure of 1.0 atm during filling, and 100% yield. iron splints = % sulfuric acid =

Determine the percent sulfuric acid by mass of a 1.61 m aqueous solution of h2so4. %

Listen base your answer to the question on the information below.propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below.c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol.what is the correct structural formula for a molecule of methanethiol

One of the few xenon compounds that form is cesium xenon heptafluoride (csxef7). how many moles of csxef7 can be produced from the reaction of 13.0 mol cesium fluoride with 12.5 mol xenon hexafluoride? csf(s) + xef6(s) csxef7(s)
