Polar molecule Polar molecules have polar covalent bonds between their constituent atoms, and the shape of the molecule is asymmetric. Therefore, the centers of positive and negative charges do not coincide. Just as there are poles … more
From the perspective of an observer on Earth, the orbits of satellites with an orbiting period of less than 24 hours appear to move westward little by little with each turn. This phenomenon occurs because of … more
There are 10 black stones and 10 white stones in your pocket. What is the distribution of the number of black stones when I take out 10 randomly? Binomial distribution When you take a stone out … more
Caution This simulation is intended to understand the principle of fission, and the proportions of the model presented may not match the reality. The nucleus was exaggerated and drawed large. The electrons around the nucleus were … more
If you click on the elements in order, the molecular weight that is summed by adding the atomic weight is displayed. For example, if you want to know the molecular weight of water (H2O), click H … more
Lorenz’s waterwheel Let’s say you have a waterwheel with a bucket with a small hole in the floor. When water drips from the faucet above, the bucket runs down and spins. Then, let’s predict which direction … more
Lead iodide sediment formation reaction If you continue to add the lead nitrate solution to a certain amount of potassium iodide solution, the amount of sediment produced will continue to increase at the beginning and will … more
Genetic diversity Suppose a child inherits chromosomes from parents and constructs a new pair of chromosome pairs. A child can receive an ‘A’ or ‘a’ from his mother and a ‘B’ or ‘b’ from his father. … more
Heat capacity ‘Heat capacity’ is the amount of heat to raise the temperature of an object by 1℃. The heat capacity of an object is the specific heat of the object multiplied by the object’s mass. … more
