With the conversion rate in the video, of the sulfur in 1 ton of coal reacting with 93. 6 kg of limestone, 1 billion tons will react with 93. 6 billion kilograms of limestone, otherwise written as 93. 6 million tons, or 93, 600, 000 million kilograms, or 93, 600, 000, 000, 000 kilograms, or an estimated 15, 600 Great Pyramids of Giza. But this is not all. Each mole of sulfurous acid will also cause 1 mole each of carbon dioxide and water vapor to be released. This equates to 935 billion moles of each, and thus 41, 140, 000 tons of CO2 and 16, 830, 000 tons of gaseous H2O. So. yeah. some pretty heavy stuff if you ask me.
(I can totally imagine my calculations being wrong, especially with all the power of ten stuff going on. Please correct me if you do find errors, thanks)

The carbonic acid result spoken of at 7: 20. I dont fully get it. It has the Calcium atom become positively charged because the acid reaction from the hydrogen donating its positively charged hydrogen atoms to the Carbonate results in the positive ionization charges to be moved into the Calcium atom as a result of the reaction. Causing the calcium to be separated and replaced by Hydrogen that then further dissolves into CO2 right? Hence why it says CO30. The 0 to denote it lost its positive charge to the calcium atom?
Am I wrong?

94 million (9. 4x10-7) metric tons of limestone per 1 billion tons of 3% sulfur coal.
1, 000, 000, 000 tons of coal - (30kgS/1tonCoal) - (1000gS/1kgS) - (1molS/32. 066gS) = 9. 356x10-11molS.
Same amount of mols Sulfur per Limestone, therefore, 9. 356x10-11molS = 9. 356x10-11molCaCO3 (Limestone.
9. 356x10-11molCaCO3 - (100. 078gCaCO3/1molCaCO3) = 9. 36-10-13gCaCO3.
9. 36-10-13gCaCO3 - (1 metric ton/10-6gCaCO3) = 9. 36-10-7 metric tons of limestone, around 94 million metric tons.

Hank: eats lemon and says that it is very sour, he then will drink water to neutralize the flavor in his mouth
Also Hank one minute later: water is the most common acid

5: 09 Hank: on the left-hand side
5: 16 Hank: and on the left hand side
Me wondering why he said left and left instead of left and right: -

why is no one here saying their teacher sent this video to them to comprehend what were the famous acid-base reactions for online classes. wow

Are transcripts of Crash Course available? I'd love them for a reference, since I'm so poor at science. It would help me teach better. Thanks!

Shouldn't there be a coefficient of 2 in front of the sulfur dioxide and water in the reactants at 6: 58? Am I doing something wrong?
