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 are insulators short answer?
What are insulators short answer? Any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator. Wood, plastic, rubber, and glass are good insulators. What are the uses of insulators? A thermos is an insulator used to keep liquids warm. Insulators work as protectors. They may protect heat, […]
Why is shale gas bad?
Why is shale gas bad? But US researchers found that shale gas wells leak substantial amounts of methane, a potent greenhouse gas. This makes its climate impact worse than conventional gas, they say – and probably worse than coal as well. Is shale gas a renewable resource? Shale gas is non-renewable, and also polluting but […]
Who is the founder of functionalism psychology?
Who is the founder of functionalism psychology? William James Which is a behaviorist most likely to study? 240 Cards in this Set Of the following, a behaviorist is most likely to study: animal learning. Pavlov repeatedly paired a buzzer with the presentation of food and measured salivation to each. In this experiment the food was […]
At what point is acceleration the greatest?
At what point is acceleration the greatest? Neglecting air resistance for the moment, the remaining force is that of gravity which is always g and directed downward. So the acceleration at the highest point is the same as at launch time, i.e. -9.8 meters/sec2 in the vertical direction. What is the acceleration just before it […]
What are the three basic types of bridges?
What are the three basic types of bridges? Bridges can be found in a variety of shapes, but 3 basic designs rule the day; beam, arch, and suspension. What are the main parts of a bridge? The main components of a bridge are the foundation, substructure, and the superstructure. Each of these core areas have […]
What makes hair follicles grow?
What makes hair follicles grow? Your hair begins growing from a root in the bottom of the follicle. Blood from the blood vessels in your scalp feeds the root, which creates more cells and makes the hair grow. How can I reopen my hair follicles naturally? Their proven benefits can help to stimulate growth and […]
Why tidal energy is bad?
Why tidal energy is bad? Intermittent: Tidal energy can only be produce electricity during tidal surges, limiting electricity generation to 10 hours per day. Expensive: Technology for generating electricity from tidal energy is relatively new and not yet commercially profitable. Tidal power plants are also expensive to build and maintain. Why is tidal power not […]
What causes automatic transmission to jerk when shifting?
What causes automatic transmission to jerk when shifting? Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues. Why does my car […]
What things reduce friction?
What things reduce friction? Silicone aerosols, oils, grease and ball bearings are all used to reduce friction. Air resistance force is the force of air pushing against a moving object. Air resistance (also called drag) is a type of frictional force. Who invented Maglev? Maglev — short for magnetic levitation — trains can trace their […]
