What are two examples of metals used in fireworks that undergo a chemical change?
Copper and strontium are two examples of metals used in fireworks. During the display, these metals are heated to high temperatures, causing them to undergo a chemical change where they emit colorful light due to electron transitions within their atoms.
How are metals and non metals recognized?
Metals have certain features which make them easy to recognize. They have a metallic luster, and they are very good conductors of electricity. They undergo chemical reactions in which they lose electrons. Non metals characteristically do not have a metallic luster, do not conduct electricity very well, and they undergo chemical reactions in which they gain electrons (or in the case of inert gases, they don't undergo any chemical reactions).
Is corrosion a chemical property or chemical change?
Corrosion, or rusting, is the oxidation of a substance, and therefore a chemical reaction. The most well known corrosion is the rusting of iron, in which the iron is oxidised by oxygen. Both metals and non-metals can therefore undergo corrosion, and it can be by any oxidising agent, and therefore not need be oxygen.
What metal is used in fireworks and why?
The metal commonly used in fireworks to create colorful sparks is a combination of various metal salts. When these metal salts are heated, they absorb energy and release it in the form of light, creating the vibrant colors we see in fireworks displays. Some common metals used in fireworks are strontium for red, barium for green, and copper for blue.
Is malleability an example of a chemical change or physical change?
Malleability is a physical property of metals.

If you watch exploding fireworks from a safe distance hat evidence of a chemical reaction can you observe?
Burning of metals in fireworks is a chemical reaction and is what makes the fireworks glow with different colors.

Is metal vs nonmetal a chemical change?
Metals and nonmetals are chemical elements, not "changes".

Corrosion is a physical property of metals?
No, corrosion is a chemical change of the metal involved.
Is corrosion of metals physical or chemical change?
It is a chemical change, where a chemical such as oxygen or chlorine combines with a metal, forming an oxide or chloride of that metal.

Malleability is a physical property of metals.
How does the relationship between ionization energy and reactivity of metals influence their chemical properties?
The relationship between ionization energy and reactivity of metals affects their chemical properties. Metals with low ionization energy are more reactive because they can easily lose electrons to form positive ions. This reactivity influences how metals interact with other substances and their ability to undergo chemical reactions.
What materials change by heat?
Materials such as metals, plastics, and ceramics can undergo physical or chemical changes when exposed to heat. For example, metals can expand or change shape, plastics can melt or burn, and ceramics can crack or break due to thermal stress. Additionally, some materials may change their properties or structure at high temperatures, affecting their mechanical, electrical, or chemical behavior.
