Is hydrogen peroxide supposed to foam? Hydrogen peroxide does not foam in the bottle or on your skin because there is no catalase to help the reaction to occur. Hydrogen peroxide is stable at room temperature. What is the changing of liquid to a gas called? At a certain temperature, the particles in a liquid […]

What is the function of sodium ion in human body?
What is the function of sodium ion in human body? Sodium is both an electrolyte and mineral. It helps keep the water (the amount of fluid inside and outside the body’s cells) and electrolyte balance of the body. Sodium is also important in how nerves and muscles work. Most of the sodium in the body […]
What does constant velocity look like?
What does constant velocity look like? Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. Given a graph as in, we can calculate the velocity from the change in distance over […]
Which is better if the discharge time of the capacitor is small or large?
Which is better if the discharge time of the capacitor is small or large? At first the current is large because the voltage is large, so charge is lost quickly and the voltage decreases rapidly. As charge is lost the voltage is reduced making the current smaller so the rate of discharging becomes progressively slower….Discharging […]
