What is observed when air is passed over heated copper powder?
When air is passed over heated copper powder, the copper powder will react with the oxygen in the air, leading to the formation of copper oxide. This reaction can result in a color change in the copper powder from its original metallic color to a reddish-brown color.
What happens when the earth rotates once what has passed?
When Earth completes one rotation, a full day has passed. This causes different parts of the planet to experience day and night as they face towards or away from the sun. The rotation also influences the Coriolis effect, which affects weather patterns and ocean currents.
Why only steel gets heated on induction hotplate?
Induction hotplates works on the principle of "production of electricity/current by the magnetic field". A copper coil in under the hotplate from which alternating current is passed, which in-turn produce magnetic field. This magnetic field produces heat in 2 ways:1. produces current in the conductive pot placed on the hotplate. (I = current)2. these currents encounter some resistance. (R = resistance)thus we can produce heat = I2RThus we saw that only conductors can get heated on a hotplate. And since steel is a conductor it gets heated. The other cookwares like glass, ceramics will not conduct any current and thus they won't get heated.
What happens when chlorine gas is passed through calcium hydroxide?
When chlorine gas is passed through calcium hydroxide, it reacts to form calcium hypochlorite, calcium chloride, and water. The chemical equation for this reaction is: 2Ca(OH)2 + 2Cl2 → Ca(ClO)2 + CaCl2 + 2H2O. This is a common method used to produce calcium hypochlorite, which is commonly used as a bleaching agent and disinfectant.
What happens when an electric current is passed the gas or vapor of an element?
When an electric current is passed through a gas or vapor of an element, it can ionize the gas, leading to the formation of plasma. This process can emit light, such as in neon signs, or be used for various industrial applications like gas discharge lamps or plasma displays. Additionally, it may also lead to chemical reactions, allowing for the creation of new compounds or molecules.
What is observed when air is passed over heated copper powder?
When air is passed over heated copper powder, the copper powder will react with the oxygen in the air, leading to the formation of copper oxide. This reaction can result in a color change in the copper powder from its original metallic color to a reddish-brown color.
When hydrogen gas passed over heated cupric oxide?
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
Does copper get heated when electric current is passed through?
yes it does

Why the water gets heated when current is passed through carbon rods in it?
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.
Why the colour of heated copper powder becomes black when air is passed over it?
When air is passed over heated copper powder, the copper undergoes oxidation, forming copper oxide. Copper oxide is black in color, which is why the heated copper powder appears black when air is passed over it.
When hydrogen gas is passed through heated calcium?
After this reaction calcium hydride (CaH2) is obtained.
What happens in 1765?
the stamp act was passed
If there is ever a conflict between a law passed by a state and one passed by the national government what happens?
The law passed by the national government is supreme
What happens to the expenses involed in complying with government regulations?
passed on to the consumer
Where did the word griddle come from?
There was a Latin word Craticula which passed into French as Gredil meaning a flat heated surface
