The carbon rods have electrical resistance. Thisi causes them to heat when current is passed through them. The water gets heated by the carbon rods.
yes it does
the water will be heated and electrolysed to give hydrogen and oxygen gases
carbon
when electric current is passed through acidified water hydrogen gas is released at the cathode..
To produce the light. When it gets heated, it glows.
when electric current is passed through acidified water hydrogen gas is released at the cathode..
When carbon dioxide is passed through lime water it will turn milky.
yes
After this reaction calcium hydride (CaH2) is obtained.
When an electric current is passed through Argon, it becomes blue
Lightning is a DC current and it will pass through your body with devastating effect. Defibrillators use a DC current to restart/reset your heart if it has stopped or gone into fibrillation. So DC current is passed through your body.
When carbon dioxide is passed through lime water it goes cloudy.
