Answer:
Empirical formula is K₃PO₄.
Explanation:
Given data:
Percentage of K = 55%
Percentage of P = 15%
Percentage of O = 30%
Empirical formula = ?
Solution:
Number of gram atoms of K = 55 / 39.098 = 1.41
Number of gram atoms of P = 15 /30.974= 0.48
Number of gram atoms of O = 30 / 15.999 = 1.88
Atomic ratio:
K : P : O
1.41/0.48 : 0.48/0.48 : 1.88/0.48
3 : 1 : 4
K : P : O = 3 : 1 : 4
Empirical formula is K₃PO₄.
Answer:
You haven't given enough information, you have to tell us how many grams of which reactant are present, as well as the initial and final temperatures of the solution.
Explanation:
The answer is D,it changes the sugar's color.
<span>The correct answer is 3. The concentration of the product and the concentration of the reactants are equal. That is because matter cannot be created or destroyed and the product cannot randomly become something else in the reaction, nor can a reactant change into something different. Simply put, you cannot turn things like water into gold because there will always be an equilibrium.</span>
