How many ions are formed during the dissociation of 500 molecules of carbonic acid, if it dissociates in the first degree by 20%, and in the second degree by 1%? Explain your answer. |

instead make u go met yo colleagues,course mates and put heads together or enter library/better still go meet yo senior In school, lecturer to help u with beta explanation, u dry run 🏃♀️ 😂 here for expo? How u go come do am if u dey Exam hall ? U go dey chew ur pen tip |

1. First degree dissociation: 20% of 500 molecules dissociate, which is 0.20 * 500 = 100 molecules. Each dissociated molecule forms one hydrogen ion (H^+) and one bicarbonate ion (HCO3^-), so a total of 100 * 2 = 200 ions are formed. 2. Second degree dissociation: 1% of 500 molecules dissociate, which is 0.01 * 500 = 5 molecules. Each dissociated molecule forms one hydrogen ion (H^+) and one carbonate ion (CO3^2-), so a total of 5 * 2 = 10 ions are formed. Therefore, The total number of ions formed during the dissociation of 500 molecules of carbonic acid is 200 + 10 = 210 ions. |

Alabidtailor:The formula for carbonic acid is H2CO3. When it dissociates in the first degree, it forms two ions - H+ and HCO3-. When it dissociates in the second degree, the HCO3- ion formed in the first degree dissociation further breaks down into H+ and CO32-. So, if 500 molecules of carbonic acid dissociate in the first degree by 20%, it means that 20% of the molecules produce two ions, and the remaining 80% do not dissociate. Therefore, the total number of ions formed in the first degree dissociation is: 500 x 20% x 2 = 200 ions If the same 500 molecules dissociate in the second degree by 1%, it means that 1% of the HCO3- ions produced in the first degree dissociation further dissociate to form two more ions, and the remaining 99% do not dissociate. Therefore, the total number of ions formed in the second degree dissociation is: 200 x 1% x 2 = 4 ions So the total number of ions formed during the dissociation of 500 molecules of carbonic acid is: 200 + 4 = 204 ions. |
