Preparation of sodium astatide NaAt.
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 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.
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.
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.
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.

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.
yes it does

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.
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.
After this reaction calcium hydride (CaH2) is obtained.

There was a Latin word Craticula which passed into French as Gredil meaning a flat heated surface
