Mixing magnesium and the product of burning magnesium with hydrochloric acid is it a physical or chemical change?
Mixing magnesium and the product of burning magnesium with hydrochloric acid would lead to a chemical change. The reaction between magnesium oxide (product of burning magnesium) and hydrochloric acid would produce magnesium chloride and water, showing a chemical reaction taking place due to the formation of new substances with different properties.
What class of fire involves the burning of wood and paper?
Class A fires involve the burning of wood, paper, cloth, and other ordinary combustibles. These fires can typically be extinguished with water, foam, or dry chemical extinguishers.
When fires are caused by oil why can they not be extinguished by water?
Fires caused by oil cannot be extinguished by water because oil is less dense than water and floats on top of it. When water is used on an oil fire, it can spread the fire by carrying the burning oil with it and causing the fire to become more intense. Additionally, the high temperatures of an oil fire can cause the water to vaporize quickly, creating steam that can disperse the burning oil and make the fire harder to control.
Why is it easier to weigh the product of burning magnesium rather than the products from a bunning candle?
It is easier to weigh the product of burning magnesium because magnesium burns in a highly controlled reaction to produce a single product, magnesium oxide, which can be easily collected and weighed. In contrast, a burning candle produces multiple products such as carbon dioxide, water vapor, and soot, making it difficult to collect and weigh all the products accurately.
Is magnesium fat or water soluble?
Magnesium is water soluble.
What will happen if I drop a strip of burning magnesium into a beaker of water?
It will stop burning
What is formed when you mix fire and water?
The fire is extinguished and some of the water is evaporated. Whatever new compounds may form depends on what is burning.

Is magnesium more reactive than lithium?
No, lithium is more reactive than magnesium because it has a higher tendency to lose electrons. Magnesium reacts slowly with water, whereas lithium reacts vigorously with water, producing hydrogen gas.
Difference between magnesium oxide and magnesium hydroxide?
Magnesium oxide is formed by burning magnesium in the presence of oxygen, while magnesium hydroxide is formed by reacting magnesium oxide with water. Magnesium oxide is more commonly used as a supplement for magnesium deficiency, while magnesium hydroxide is often used as an antacid or laxative due to its ability to neutralize stomach acid and promote bowel movements.

How does magnesium react with metal?
On burning in air, magnesium produces a brilliant white light. they are highly flammable in their pure form when molten or in powder or ribbon form. Burning or molten magnesium metal reacts violently with water. When working with powdered magnesium, safety glasses with welding eye protection are employed, because the bright white light produced by burning magnesium contains ultraviolet light that can permanently damage the retinas of the eyes.
Does the presence of ice make magnesium burn hotter?
Yes, the presence of ice can make magnesium burn hotter because the reaction between magnesium and water releases hydrogen gas, which can ignite and increase the intensity of the burning.
What changes considered as oxidation reduction reaction burning of magnesium ribbon or electrolysis of water?
both reactions are redox reactions
Can you give an example of a sentence using word extinguish?
Nancy poured baking soda on the grease fire to extinguish the flame.
