What is Peritectoid?
What is Peritectoid? In binary systems, the peritectoid is the transformation of two solid phases in an alloy system, forming a new phase. These reactions happen in a similar way to peritectic transformations (see Peritectic), however, they only occur in the solid state. Is Cementite FCC or BCC? The alpha phase is called ferrite. Ferrite […]

What is a disadvantage of hydrogen fuel cells?
What is a disadvantage of hydrogen fuel cells? There are disadvantages to using hydrogen-oxygen fuel cells in cars. These include: hydrogen is in the gas state at room temperature and pressure, so it is difficult to store in the car. fuel cells and electric motors are less durable than petrol engines and diesel engines, so […]

What causes sodium voltage-gated channels to open?
What causes sodium voltage-gated channels to open? When a stimulus reaches the threshold at the axon hillock, an action potential is generated. An action potential relies on many protein channels. All the voltage-gated Sodium channels open when the membrane potential reaches around -55 mV and there’s a large influx of Sodium, causing a sharp rise […]
What does the bubbling indicate?
What does the bubbling indicate? When substances are put in the same container like, CaCO3 and HCl . A reaction occurs and bubbles escape the container (effervescence). These bubbles are actually gas fumes, and this shows that a new gaseous product is formed. Here, bubbling indicates our chemical reaction. What are the bubbles that you […]
