Answer:
The correct answer is 0.50 mol (NH₄)₃PO₄
Explanation:
The balanced chemical equation between liquid ammonia (NH₃) and H₃PO₄ is the following:
3 NH₃ + H₃PO₄ → (NH₄)₃PO₄
According to the equation, 3 mol of ammonia produce 1 mol of ammonium phosphate. Thus, the stoichiometric ratio is 1 mol (NH₄)₃PO₄/3 NH₃. To calculate the moles of (NH₄)₃PO₄, we multiply the ratio by 1.50 mol NH₃:
1.50 mol NH₃ x 1 mol (NH₄)₃PO₄/3 NH₃ = 0.50 mol (NH₄)₃PO₄
charge of elements increases by one as you move from left to right.
Hypothesis refers to the discovery and raising of problems in observation, after experiment and fact verification, the various correct and reasonable explanations of the problem can rise to theory and become a successful hypothesis.
The oxidation number of I (iodine) decreases the in the described chemical reaction from 0 to -1.
Explanation:
We have the following chemical reaction:
I₂ + 2 KCl → KI + Cl₂
The following atoms have a change in the oxidation number:
I with a 0 oxidation number (in I₂) goes to I with -1 oxidation number (in KI) by receiving 1 electron.
Cl with a -1 oxidation number (in KCl) goes to I with 0 oxidation number (in Cl₂) by losing 1 electron.
