Carbonic acid is heated to carbon dioxide and water
H2CO3 =△= H2O + CO2↑
Copper reacts with oxygen to form copper oxide under heating condition
2Cu + O2 =△= 2CuO

7. If an experiment has N equal possible results, and event a occurs when one of M results occurs, then the probability of event a occurrence P (a)=
8. Let the probability of event a be p = P (a). Now repeat the experiment n times independently, and try to find the probability of a appearing at least once
9. It is known that the probability of event a in a test is p (0
10. For the event with probability p, the probability of event occurrence > = k times in n independent repeated tests Probability p event, the probability of K times of event occurrence in n independent repeated tests P (x = k) = C (n, K) * P ^ k * (1-p) ^ (n-k), what function is convenient to calculate: the probability of event occurrence > = k times in n independent repeated tests

14. The calculation of inflation rate and currency depreciation rate Is the rate of inflation the same as the rate of currency depreciation Last time I saw two questions in the political reference book, which involved these two concepts, but the algorithm was very different The current price of goods is 10 yuan. (1) Q: what's the price when the inflation rate is 20% Calculation: 10x (1 + 20%) = 12 (yuan) (2) What is the price when the devaluation rate is 20%? Calculation: 10 divided by (1 + 20%) equals 12.5 yuan Which is the right one? Or is that the way it is calculated I just don't understand why some use multiplication and some use division
