Given the formula of 5.00mL ampule of a 0.100 M naphthalene solution in hexane triggered by a flash of light, the naphthalene molecules emit 8.27% of photons. What is a photon? Photons are tiny quantum particles that make up light and serve as electromagnetic radiation’s fundamental unit. Photons display wave-particle duality, which means … Read more
After a certain amount of time has passed, the potential energy in a discharging circuit which was initially fully charged will drop to around 37%. This final value is known as the one time constant. What is one time constant? The time required to charge a capacitor to 63.2 percent of the applied … Read more
We retain very little of what we hear. In fact, studies show that we only remember around 10% of what we hear. This is because our brain can only process so much information at once. This number can also get lower or higher depending on a variety of factors, such as how well we were … Read more
Between 0.2 percent and 4 percent of the air is made of water vapor. The amount of water in the atmosphere is regulated by temperature. What is water vapor? Water vapor is a type of gas that is formed when water vaporizes. This means that it turns into a liquid and then a gas. Water … Read more
The respiratory system contributes to the loss of 10%–20% of body water. This includes both the production of sweat and breathing. This amount can vary depending on a person’s activity level and body composition. What is the respiratory system? The respiratory system is responsible for taking in air and breathing it out. The lungs are … Read more
5 moles of water (90 grams of water) are incorporated into the structure of a mole of CuSO4 5H2O. As a result, the water content of CuSO4 5H2O is always 90/250, or 36%, by weight. What is CuSO4 5H2O? CuSO4 5H2O, also known as copper sulfate pentahydrate, is a chemical that appears as odorless blue … Read more
Using the drag sampling technique, researchers gathered tick samples from June to October 2017 in 23 locations throughout the city of Ottawa, including public parks, hiking trails, and woodlands. About 30% of the 239 ticks gathered had burgdorferi bacteria in them. Burgdorferi bacteria is what causes Lyme disease. What ticks are in Canada? There are … Read more
Many studies have been done on the effects of organic farming on organisms. Out of all the studies, only 16% showed a negative effect when it comes to species richness. What is organic farming? Organic farming is a way of farming that uses methods that do not damage the environment. These methods include growing crops … Read more
About 0.4% of the solar nebula’s mass consisted of rocky material. This means that it is not just gas and plasma but actual rocks that make up our star. What kind of material in the solar nebula could remain solid at high temperatures? Most materials in the solar nebula are gas at temperatures near the … Read more
By far, the most prevalent gases in the solar nebula are hydrogen and helium. They make up roughly 98 percent of it. Only 2% of the solar nebula’s mass is made up of other elements combined. What type of spectrum does the gas in a planetary nebula produce? A planetary nebula emits an emission spectrum. … Read more
