Answer:
2 chloride ion, Cl¯
Explanation:
The formula for calcium chloride is CaCl₂.
Next, we shall write the balanced dissociation equation for calcium chloride, CaCl₂. This is illustrated below:
CaCl₂ (aq) —> Ca²⁺ + 2Cl¯
From the balanced equation above,
We can see that calcium chloride, CaCl₂ contains 1 calcium ion, Ca²⁺ and 2 chloride ion, Cl¯.
Therefore, we can conclude that for every 1 calcium ion, Ca²⁺, there are 2 chloride ion, Cl¯.
Assuming conditions are at 25c and 1 bar 101.25 Kpa 1 mole of gas is equal to 22.4 L
So if you have 500L of ar gas the you have : 500L / 22.4 × 1 Mole = 22.3 moles of ar after accounting for sig figs..Hope that helps
Given 3.72 g of P and 21.28g of Cl, converting these to moles: ( 3.72 g P)(mol P/30.97 g P) = 0.12 mol P (21.28 g Cl)(mol Cl/35.45 g Cl) = 0.60 mol Cl P:Cl = 0.12/0.60, therefore P: Cl =1/5 Therefore, PCl5 hope it helps
