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 about the liquid level.

once fuel is discharged from the cylinder, the fuel leaves the cylinder as a gas.

Explanation:

Propane may be a fuel that's sold in rigid, pressurized cylinders. Most of the fuel in an exceedingly cylinder is liquid, with gas within the area on top of the liquid level. once fuel is discharged from the cylinder, the fuel leaves the cylinder as a gas. fuel gas is employed as a fuel by compounding it with element within the air and igniting the mixture, as depicted by the balanced equation below,

+ 502(g) n, 3C02(g) + 4H20(l) + two,219.2 kJ

A small quantity of methane thiol, that incorporates a distinct odor, is supplementary to the fuel to assist customers discover a propane leak, In methane thiol, the odor is caused by the thiol practical cluster (#SI-I). Methane thiol, CH3SH, incorporates a structure that's terribly like the structure of alcohol. Based on the data given, draw a molecular formula within the box provided for a molecule of methane thiol.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
