Why when magnesium ribbon is burnt the ash is heavier?
When Magnesium burns, it is actually combining with oxygen in the air to form a new compound, magnesium oxide. If we were to carefully weigh a piece of magnesium before and after burning it, you would see that its weight increased by about one third. For example, if you start with 100 grams of magnesium, after the burn you would end up with about 130 grams of magnesium oxide. The fact that the magnesium oxide you create by burning is powdery, means that it takes up more space (size or volume) than the solid magnesium did.
What is one advantage of using magnesium metal in airplanes and bicycles rather than iron or aluminum?
Magnesium is lighter. As long as it's also strong enough it can lead to a lighter end product.

What is the gymnastics event with the ribbons?
There is a ribbon which is the thing at the end of the ribbon stick. It is connected by this hook which holds the ribbon. So the "ribbon" is called a ribbon :)
When did Blue Ribbon Soundworks end?
Blue Ribbon Soundworks ended in 1995.
When did Pabst Blue Ribbon Bouts end?
Pabst Blue Ribbon Bouts ended in 1955.
When did Fleet Marine Force Ribbon end?
Fleet Marine Force Ribbon ended in 2006.
What happens when a piece of Mg ribbon is place in a test tube with Hydrochloric acid and cover the mouth of the test tube?
Metal + Acid --> Salt + Hydrogen Gas. As a result, the end product of this reaction is magnesium chloride and hydrogen gas. Covering the mouth of the test tube simply prevents the hydrogen gas from escaping, and allows you to test for its presence by using a lighted splint.
How do you stop a ribbon from fraying by burning it?
You simply take the frayed end and put it over a naked flame. The flame sort of welds the ribbon or rope together and so you end up with a very hard end instead of a frayed end.
What kind of vibration might you see in a colored ribbon?
If the ribbon end is shaken up and down you would see a transverse wave.
The burning magnesium becomes uncontrolled oops how will this procedural error affect the reported mole ratio of nagnesium to oxygen in the analysis?
You will end up having less oxygen because it goes in doubles, and it is considered as flammable, and magnesium wouldn't burn if you didn't trap oxygen inside the magnesium foil. Some of the Magnesium WILL boil away as it burns, but you will end up with less oxidation anyway.
How can I make ribbon bookmarks?
To make ribbon bookmarks, cut a piece of ribbon to your desired length, add a decorative charm or bead to one end, and secure the ends with fabric glue or by sewing them together. You can also attach a paperclip or clip to the other end for easy placement in your book.
