What is the chemical reaction when you burn a candle?
When a candle burns the reactions that occur are both chemical and physical. Chemical reaction is when substances are mixed together to create a different material. A physical reaction is when there is a change in the appearance of the substance. For example when water turns to ice, and when chocolate melts. The chemical reaction that happens when a candle burns is when the oxygen combines with the paraffin. When this happens, this makes carbon dioxide, water and other materials. When the wax reacts with the oxygen it gives off light and heat. The more oxygen that reacts with the candle when it burns, the brighter and hotter it is. The physical reaction that occurs is when the candle wax melts. When the energy (light and heat) inside of the candle is released it helps to melt the candle.
What happens to gallium when it melts?
Gallium is a metal that is solid at room temperature but melts at a low temperature of 85.57°F (29.76°C). When gallium melts, it becomes a liquid with a silvery appearance. It has a unique property where it can remain in a liquid state over a wide temperature range.
What happens to ice nd magnesium when heated?
When ice is heated, it melts into water and eventually evaporates into steam as it reaches its boiling point. When magnesium is heated, it undergoes a chemical reaction with oxygen in the air to form magnesium oxide and emits a bright white light.
Does a candle need oxygen to burn?
Yes, a candle needs oxygen to burn. When the wick is lit, it melts the wax, which vaporizes and combusts, reacting with oxygen in the air to produce heat and light. This process is known as combustion.
What melts at close to the boiling point of water?
If it's an element that your looking for, I'm thinking it's sodium. Water boils at 100 degrees Celsius, and Sodium melts at 98 degrees Celsius. I hope that helped :) have a blessed day !
Which element melts at the lower temperature-oxygen or mercury?
Mercury has a lower melting point compared to oxygen. Mercury melts at -38.83°C, while oxygen melts at a much lower temperature of -218.79°C.
