The answer to the question is option <u>D</u>
Okay so, 24.00 mL of a 0.25 M NaOH solution is titrated.
"Decaying swamps are covered with seawater" step ONLY occurs in the formation of coal.
<u>Option:</u> B
<u>Explanation:</u>
Coal production continues in regions of swampy wetlands because groundwater is near to or just above the topsoil. Because of this, organic matter is created quickly by the flora present-faster even than it can be broken down. Layers of organic matter are deposited in these areas, and then buried.
Based on the plants and circumstances present, the mechanism that produces coal varies somewhat in various areas but the ultimate method is similar. Coal production has two primary phases: peatification, and coalification. It is a solid black, readily combustible fossil fuel containing a large quantity of carbon-based material-about 50 percent of its mass.
