When ions combine to form neutral compounds, their charges are usually crisscrossed to cancel out any net charge. For this example, Cr3+ and O2- have different charges. Applying the crisscross method, the neutral compound is Cr2O3. This proportion balances out a net charge because two Cr3+ gives a +6 charge, and three O2- gives -6 charge.
<u>Answer:</u> The concentration of hydrogen ion and bromoacetate ion is 0.0132 M and 0.0132 M resepectively and that of bromoacetic acid is 0.0868 M
<u>Explanation:</u>
We are given:
Molarity of bromoacetic acid = 0.100 M
Percent of ionization = 13.2 %
The chemical equation for the ionization of bromoacetic acid follows:
1 mole of bromoacetic acid produces 1 mole of bromoacetate ion and 1 mole of hydrogen ion
Molarity of hydrogen ion = 13.2 % of 0.100 =
Molarity of bromoacetate ion = molarity of hydrogen ion = 0.0132 M
Molarity of bromoacetic acid = Molarity of solution - Molarity of ionized substance
Molarity of bromoacetic acid = 0.100 - 0.0132 = 0.0868 M
Hence, the concentration of hydrogen ion and bromoacetate ion is 0.0132 M and 0.0132 M resepectively and that of bromoacetic acid is 0.0868 M
Answer:
3.7 mol O₃
Explanation:
Step 1: Write the balanced equation
2 O₃ ⇒ 3 O₂
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₃ to O₂ is 2:3.
Step 3: Calculate the number of moles of O₃ required to produce 5.5 moles of O₂
We will use the previously established molar ratio.
5.5 mol O₂ × 2 mol O₃/3 mol O₂ = 3.7 mol O₃

A mixture of calcium acetate and sodium phosphate would produce as a precipitate.
<h3>Precipitation reaction</h3>
Precipitates are insoluble salt formed from the reaction of two soluble salts.
The equation of the reaction between calcium acetate and sodium phosphate is represented by the equation below:
The produced in the reaction is an insoluble salt and, hence, a precipitate.
