What reaction produces O2? When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off. To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water. What is the product of 2H2 […]
What is the most important force driving erosion?
What is the most important force driving erosion? Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. What is the biggest driver for soil […]

How a renewable resource can run out and give examples?
How a renewable resource can run out and give examples? Non-renewable resources are used faster than they can be replaced. Once they’re gone, they are, for all practical purposes, gone. Renewable resources are so abundant or are replaced so rapidly that, for all practical purposes, they can’t run out. Renewable resources include solar, wind, hydro, […]
Why do I feel sick during a storm?
Why do I feel sick during a storm? Approaching storms lower the air pressure. When atmospheric pressure decreases body tissues swell slightly. This can put increased pressure on joints and sinuses. Low temperatures also causes blood viscosity, or thickness. Does thunder affect mood? Thunderstorms are dramatic events, so it’s not surprising that they often bring […]
How will you describe primary colors?

Secondary colors are mixed from two primary colors adjacent to each other on the color wheel. How many primary colors are there? three What are 4 […]
Why does binding energy decrease?
Why does binding energy decrease? The above figure illustrates that as the atomic mass number increases, the binding energy per nucleon decreases for A > 60. As the repulsive forces are increasing, less energy must be supplied, on the average, to remove a nucleon from the nucleus. In other words, the BE/A has decreased. What […]
Why is copper used instead of gold?
Why is copper used instead of gold? Gold, for example, is an excellent conductor of electricity, but it costs several times more than copper. If companies used gold to manufacture electrical wires, they’d essentially waste money, as copper is more conductive and costs less than its goal counterpart. What is the disadvantage of using aluminum […]
