Is francium used in bombs? Because the alkali metals react viciously with water, a huge explosion will result when the two substances are combined, especially with the heavier alkalis like cesium and francium. This is the explosion necessary for our francium Bomb. First off, francium is highly rare. Why is francium dangerous? Useful to Scientists […]
What is scatter diagram?
What is scatter diagram? The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve. What is purpose of using scatter diagram? A scatter diagram (Also known as scatter plot, scatter […]
What are the 5 different types of reactions?
What are the 5 different types of reactions? The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. What are 10 indicators of a chemical change? Bubbles of gas appear. Gas-producing reactions run to completion when the gas can leave the reaction mixture. A precipitate forms. A color change occurs. The […]
Where is nitrogen found?
Where is nitrogen found? Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. How bad is nitrogen for you? Excess nitrogen in the atmosphere can produce pollutants such as ammonia and ozone, which can […]
Is Colour change a physical or chemical property?
Is Colour change a physical or chemical property? Color. The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is […]
What happens to the difference in arrival time between P waves and S waves as the distance from the epicenter increases?
What happens to the difference in arrival time between P waves and S waves as the distance from the epicenter increases? The time between the arrival of the p-wave and s-wave becomes greater and greater as the distance from the epicenter increases because p-waves have a faster velocity than s-waves, meaning p-waves arrive at a […]
What determines if a single replacement reaction will occur?
What determines if a single replacement reaction will occur? where one element is substituted for another element in a compound to generate a new element and a new compound. We predict a single replacement reaction will occur when a less reactive element can be replaced by a more reactive element in a compound. Is Rusting […]
Can eating less meat help reduce climate change?
Can eating less meat help reduce climate change? In short, even if you aren’t already a vegetarian, cutting out some meat, especially red meat and large predatory fish, and eating lower on the food chain overall can help significantly lower your personal greenhouse gas emissions. Why is eating meat bad for environment? It causes climate […]
How long does it take for UV light to kill fungus?
How long does it take for UV light to kill fungus? one to two hours Can LED light kill mold? LED light is killing bacteria, fungus and mold, and the scientific community has validated the results. Intensities of 400 to 420 nanometers (nm) did the trick, 405 being the sweet spot for bacteria deactivation. In […]
Why do I like sunsets?
Why do I like sunsets? It has been proven that watching the sunrise or sunset gives you a better sense of gratitude for the earth. When you are caught up in the natural beauty of the Earth (like a sunset), you rid yourself of any distractions and feel higher levels of satisfaction and gratitude for […]
