Sara burns a candle. Candle wax (paraffin) has a chemical formula of C25H52. The combustion of the candle has the following equation: C25H52 + 38 O2 = 25 CO2 + 26 H2O

After a few minutes, Sara puts the lid on the candle, and the flame goes out. Sara weighs the candle before and after the experiment. She discovered she has burned 1.4 grans of paraffin. If the expirement actually profuced 2.1 grams of water, what was the percent yield of water for this experiment?

A. 116%
B: 2.8%
C: 133%
D: 2.1%

Simple stoichiometry, pls help im on edge

Based on the equation and the information in the table, what is the enthalpy of the reaction?

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
