Sodium chloride and iodine
Lungfish are thought to be related to the first creatures that crawled out of the water to colonize land. The new findings support the theory that walking first arose underwater, preceding the move onto land and the development of toes and limbs adapted to land perambulation. ..
The one with the highest pH would be a solution with 100 mL of water and also 20 mL of 0.1 M NaOH is added. Solutions without buffers would have the highest pH since the resistance to change is very low. Hope this answers the question.
Im going to assume you mean the structural formula of butane, which is C4H10. which mean that it has 4 carbon and 10 hydrogen
The answer would be 1952.5 grams of potassium sulfate solution. The way to get the answer is to use the equation, 617/x = 31.6%/1 and then cross multiply to get 31.6%x= 617grams and then 0.316x=617 grams so then x = 617/0.316= 1952.5 grams.
