What is the charge of a cathode and how do you remember it?

The cathode is negatively charged. A good way to remember this is thinking of what it's doing. A cathode attracts cations which are positively charged. In order to attract a positive charge, the charge on the electrode must be oppositely charged. So it has to carry a negative charge. The opposite is true for the anode. Since it attracts anions which are negatively charged, the electrode must carry a positive charge.


If an atom is negatively charged what must have occurred?

This atom has won electrons.


Do the charge in ion compound must be equal?

An ion is always electrically charged.


Why pressure inside of cylinder must equal to pressure outside?

For an engine to work efficiently, the pressure inside the cylinder must be equal to the pressure outside to allow for proper combustion and expansion of gases. This ensures that the engine can generate the necessary power to move and operate effectively. Any difference in pressure between the inside and outside of the cylinder can lead to issues such as poor performance, engine knock, or even damage to the engine.


Why must the water levels inside and outside the gas collection cylinder must be the same before the volume gas is measured and collected?

The water levels inside and outside the gas collection cylinder must be the same to ensure that the pressure inside the cylinder is equal to atmospheric pressure. This balance prevents the creation of a vacuum or excess pressure, which could lead to inaccurate volume measurements of the gas. Additionally, equal water levels help to eliminate the effects of hydrostatic pressure differences, allowing for a precise and consistent reading of the gas volume collected.

Why must nitrogen used only with regulator when it is charged into a system?

Nitrogen must also have its pressure regulated before it can be used. The pressure in the cylinder is too great to be connected to a system. If a person allowed nitrogen under cylinder pressure to enter a refrigeration system, the pressure could burst some weak point in the system.
