What are the 5 major factors that affect reaction rate? Five factors typically affecting the rates of chemical reactions will be explored in this section: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the […]
What type of reaction is magnesium sulfide?
What type of reaction is magnesium sulfide? Magnesium sulfide reacts with water forming hydrogen sulfide and magnesium hydroxide. It reacts with phosphoric acid to give magnesium phosphate and hydrogen sulfide. Magnesium sulfide reacts with hydrochloric acid to produce magnesium chloride and hydrogen sulfide. Is magnesium sulfide acidic or basic? Magnesium Sulfide is a moderately water […]
Can alpha particles pass through aluminum foil?
Can alpha particles pass through aluminum foil? The vast majority of alpha particles pass straight though a piece of metal foil as if it was not there. Some alpha particles are deflected (scattered) by an angle of about 1o as they pass through the metal foil. Can aluminum foil serve purpose in alpha scattering experiment? […]
Which sound wave is the loudest?
Which sound wave is the loudest? The loudest a sustained sound can possibly be on Earth’s surface is 194 dB—which is when the amplitude of the sound wave is so intense that the low pressure part is a perfect vacuum (the wave alternates between double the normal atmospheric pressure and no air at all—not something […]
What does a flat horizontal line mean?
What does a flat horizontal line mean? Horizontal line (Coordinate Geometry) Definition: A straight line on the coordinate plane where all points on the line have the same y-coordinate. A horizontal line has a slope of zero. As you move to the right along the line, it does not rise or fall at all. What […]
What happens to work when gas is compressed?
What happens to work when gas is compressed? When the gas expands against an external pressure, the gas has to transfer some energy to the surroundings. Thus, the negative work decreases the overall energy of the gas. When the gas is compressed, energy is transferred to the gas so the energy of the gas increases […]
How many miles can I drive in 1 hour?
What is the formula for GPE and do a calculation?
Are volcanoes randomly distributed?
Are volcanoes randomly distributed? Volcanoes are not randomly distributed over the Earth’s surface. Most are concentrated on the edges of continents, along island chains, or beneath the sea forming long mountain ranges. Major tectonic plates of the Earth. Are earthquakes epicenters randomly distributed? Earthquakes are not randomly distributed around the earth, rather they are located […]
Can you take off without flaps?
Can you take off without flaps? It is possible to take off and land without slats and flaps, but it requires high speeds and extremely long runways. The use of slats and flaps for takeoff is determined in tables or by computers taking into account the engine thrust, aircraft weight, runway length, obstacles and braking […]
