What is a chemical change?
A chemical change is a change in which a substance turns into a completely different substance that can't be reversed. A chemical change often happens when a substance burns (not to be confused with evaporation or melting of a substance), changes colors, a substance spoils or rusts, photosynthesis or respiration, and/or a substance tarnishes.Some examples are a bike rusting, burning bread to make toast, fireworks exploding, milk spoiling, a leaf changing color, mixing eggs and flour for a batter, baking a cake, etc.A chemical change will NOT dissolve, go through a state of matter (sublimation, decomposition, melting, freezing, evaporation, and condensation), breaking or tearing of a substance, and/or anything that can be reversed back.A chemical change is one in which one or more new substances are formed. Simple examples include burning and rusting.
Meg has 18 feet of ribbon that she wants to divide into of a foot pieces. How many of a foot pieces are there in 18 feet?
If you have 18 feet of ribbon and you want to cut the ribbon every 12 inches which is a foot. You will have 18 twelve inch pieces. if I am understanding your question correctly. Eighteen feet would equal 18 one foot pieces.
What are the advantages of identifying an organisms by scientific name?

What is the word equation for burning magnesium ribbon?
magnesium + oxygen gas ----D magnesium oxide
What is the chemical composition of magnesium ribbon?
that is magnesium itself, in the form of a ribbon
What is the balanced chemical equation of hydrochloric acid and magnessium ribbon?
The balanced chemical equation for the reaction of hydrochloric acid (HCl) with magnesium ribbon (Mg) is: 2HCl + Mg -> MgCl2 + H2 This reaction produces magnesium chloride (MgCl2) and hydrogen gas (H2).
Is magnesium ribbon a mixture or a compound?
Magnesium chloride (MgCl)2 is a chemical compound.
Is magnesium ribbon an element?
yes it is, it is part of the periodic table
Is burning a strip of magnesium ribbon a chemical or physical change?
Burning a strip of magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This reaction results in the formation of new substances with different properties than the original magnesium ribbon.
Is burning a magnesium ribbon a physical change?
Burning a magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This results in a new substance being formed with different chemical properties than the original magnesium ribbon.
Is a magnesium ribbon fizzing in acid a physical change or chemical?
The reaction of a magnesium ribbon fizzing in acid is a chemical change. This is because new substances are formed during the reaction as the magnesium reacts with the acid to produce magnesium ions and hydrogen gas.
Does Magnesium Ribbon evaporate?
Magnesium ribbon does not evaporate in the traditional sense. When heated to high temperatures, magnesium undergoes a chemical reaction known as oxidation, where it combines with oxygen from the air to form magnesium oxide. This process is not considered evaporation.
Is magnesium metal and magnesium ribbon the same?
Yes. Magnesium ribbon is magnesium metal in the shape of a ribbon.
Products of Mg ribbon ASH plus HCl?
When magnesium ribbon reacts with hydrochloric acid (HCl), magnesium chloride forms along with hydrogen gas being produced as a byproduct. The chemical equation for this reaction is: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)
Is magnesium ribbon pure?
No, magnesium ribbon are not pure. They have to be rubbed with sand paper, this removes the impurities on them
