The solubility of substance depends upon the temperature. In present case, the solubility of KCl is 84g/100g at <span>50.oC.
This means that, maximum 84g of KCl can be dissolved in 100g of water (at </span>50.oC) to form solution. This solution is referred as saturated solution.
Thus, 84g of <span>KNO3 must be dissolve in 100 grams of water to form a saturated solution at 50 oC.</span>
Answer:
I think its either A or B.
Explanation:
The reason I don't think it can be B or C is because both have too do with thinking. Technology does not control how you think, so those should stay about the same. Technology can help prove theories and hypothesis' to be true, but they could also make more observations due to the technology they didn't have before. I believe the answer is A, but I'm not 100% sure. Good Luck, i helped as best as i thought possible.
The equation NaHco3+hc2h3o2=nac2h3o2+h2co3 is already balanced.
Reaction information:
Nahcolite + Acetic Acid = Sodium Acetate + Carbonic Acid
Reactants:
Nahcolite - NaHCO3 :
Molar Mass, Oxidation State
Acetic Acid - HC2H3O2
Molar Mass, Oxidation State, Ethanoic Acid, Methanecarboxylic Acid, Ch3-Cooh, Acetic Acid; Glacial, etc
(NaHCO3 + HC2H3O2 = NaC2H3O2 + H2CO3)
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
You can wait until he either breaks up (if he does) or if just forget about him and go for another guy.
