How can you tell the difference between aluminum and magnesium? Most recent answer Magnesium versus aluminum is highly reactive and less stable than aluminum. Magnesium, when compared to aluminum, is softer and more expensive, and has the tendency to bend easily. Magnesium, when compared to aluminum, is lightweight and valuable, whereas forged aluminum is stronger. […]
What are 4 chemical properties of oxygen?
What are 4 chemical properties of oxygen? Oxygen is a colorless, odorless, tasteless gas. It changes from a gas to a liquid at a temperature of -182.96°C (-297.33°F). The liquid formed has a slightly bluish color to it. Liquid oxygen can then be solidified or frozen at a temperature of -218.4°C (-361.2°F). What are 5 […]
How old is the Grand Canyon in 2020?
How old is the Grand Canyon in 2020? Well, the Grand Canyon is a hodgepodge of old and new sections, as the researchers found in a recent study published in the Nature Geoscience journal. Some scientists believe that the Grand Canyon is 70 million years old. Can you get in trouble for stealing a rock? […]
Which type of lever is scissors?
Which type of lever is scissors? Other examples of first class levers are pliers, scissors, a crow bar, a claw hammer, a see-saw and a weighing balance. In summary, in a first class lever the effort (force) moves over a large distance to move the load a smaller distance, and the fulcrum is between the […]

What weather do cold fronts bring?
What weather do cold fronts bring? A cold front forms when a cold air mass pushes into a warmer air mass. Cold fronts can produce dramatic changes in the weather. As the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning. […]
Can a small capacitor kill?
Can a small capacitor kill? Obviously the larger the capacitor, the higher the voltage, the greater the risk of a lethal shock becomes. A really small capacitor charged to a high voltage will not kill you, for example a 100pF capacitor charged to 10kV will only give you a mild static shock. Is a 1000uF […]
How do you find the refractive index of water?
How do you find the refractive index of water? The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in […]
What are two types of scientific explanation?
What are two types of scientific explanation? Among the most common forms of explanation are causal explanation; deductive-nomological explanation, which involves subsuming the explanandum under a generalization from which it may be derived in a deductive argument (e.g., “All gases expand when heated; this gas was heated; therefore, this gas expanded”); and … Is Hempel […]
What is the NaHCO3 test?
What is the NaHCO3 test? Sodium bicarbonate, with the chemical formula NaHCO3, is the white powder widely known as baking soda. The basic test for the presence of carbonate salts is a reaction with a diluted acid solution that leads to release of bubbles of the gas carbon dioxide and follows the reaction: NaHCO3 + […]
