Why do s block elements not act as catalysts? State how a catalyst speeds up a chemical reaction. Suggest why ions from s block elements do not usually act as catalysts. Because only exist in one oxidation state. Give one reason why, in the absence of a catalyst, the activation energy for the reaction between […]
Does light travel faster in glass than in water?
Does light travel faster in glass than in water? In water, the refractive index is 1.3 and in glass, it is 1.5. Therefore, light travels faster through water, than it travels through glass. Why does light pass through glass? Photons pass through glass because they are not absorbed. And they are not absorbed because there […]
Do transistors amplify voltage?
Do transistors amplify voltage? A transistor can amplify current and it can amplify voltage and it can do BOTH at the same time. A transistor can also amplify the voltage is “sees” on the base. It does this in common-emitter mode where the emitter is connected to the 0v rail and the collector has a […]
What happens when gas volume increases?
What happens when gas volume increases? If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the […]
What energy breaks down carbohydrates using 1 to 2 minutes of energy?
What energy breaks down carbohydrates using 1 to 2 minutes of energy? Answer: Lactic Acid energy system starts to feed the muscle energy if the activity is longer than 6 seconds but less then two minutes. Hope it helps. What’s the difference between glucose and ATP? Answer: In terms of energy there is a difference […]
What happens to extra electrons in a charged object when it becomes grounded?
What happens to extra electrons in a charged object when it becomes grounded? Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of […]
Are Airboats noisy?
Are Airboats noisy? But according to the preliminary draft of the scientific study, even an airboat fitted with a muffler exceeds 90 decibels at open throttle. The reason is that as power increases, the propeller makes more noise than the motor. “I think everybody understands there has to be some kind of muffling system,” Huffman […]
Why is pressure not dependent on mass?
Why is pressure not dependent on mass? Static Fluid Pressure The fluid pressure at a given depth does not depend upon the total mass or total volume of the liquid. Because of the ease of visualizing a column height of a known liquid, it has become common practice to state all kinds of pressures in […]
