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¯.
If we consider a combustion reaction of Methane:
The balanced equation is:
CH4 + 2O2 ---> 2H2O + CO2
The rate of appearance of H2O is rH2O, rate of disappearance of O2 is -rO2
(rH2O)^2 = (-rO2)^2
rH2O = -rO2
Quantitative observations include numerical data. Ex: 32 degrees, 10 inches, etc.
