What are the strongest and weakest bonds?
What are the strongest and weakest bonds? This means Ionic bonds tend to dissociate in water. Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.” What is […]
Which country has the most tundra?
Which country has the most tundra? The tundra is a treeless polar desert found in the high latitudes in the polar regions, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as sub-Antarctic islands. Why are tundras so cold? The temperatures are so cold that there is a layer of permanently frozen ground […]
What is the difference between 1s and 2s orbital?
What is the difference between 1s and 2s orbital? 1s orbital is the closest orbital to the nucleus. 2s orbital is the second closest orbital to the nucleus. Energy of 1s orbital is lower than that of 2s orbital. 2s has comparatively higher energy. Does 3s have higher energy than 2s? In hydrogen the energy […]
How do children learn observations?
How do children learn observations? Children learn and imitate behaviors by watching and listening to others. This is sometimes called “observational learning,” when children can learn things simply by observing others. Children are learning about the behavioral choices of others and also about the consequences of those behaviors. What are the 3 key concepts of […]

What fertilizer makes plants grow faster?
What fertilizer makes plants grow faster? High-nitrogen fertilizers are known for causing huge growth in plants, which is why many types are rich in nitrogen or include it as the main component. Fertilizers high in nitrogen will also restore bright green hues to your foliage. Which fertilizer works best? Best all-purpose fertilizers Jack’s Classic 20-20-20 […]
What is coefficient of rolling resistance?
What is coefficient of rolling resistance? The coefficient of rolling friction or resistance is the indication of how great the rolling resistance is for a given normal force between the wheel and the surface upon which it is rolling. Because of the various factors, the coefficient of rolling friction is usually determined experimentally. How do […]
