I have this same worksheet that has the following questions that I have to answer: Iron rusts. Sodium hydroxide dissolves in water. A safety match ignites and burns. A cube of ice melts to form a puddle of water. Icicles form at the edge of a rof. Water is heated and changed into steam. Milk goes sour. A chocolate bar melts in the sun. Acid on limestone produces carbon dioxide gas. Vinegar and baking soda react. A tea kettle beings to whistle. Wood and leaves rot to form humus. So, I believe that a safety match igniting and burning is a chemical change. I have many Wiki results from that, and some put physical change. I don't think it's a physical change because the fire is on the match, and once it blows out, it creates that black substace which ISN'T fire. It creates a new substance that wasn't there before. Basically, the red part of the match and the fire created that new substance. I hope this helped! Sorry if this is wrong info. *-*
Yes, burning a match is considered a chemical change because it involves a chemical reaction that changes the composition of the matchstick and produces new substances like ash, carbon dioxide, and water vapor. This is different from physical changes, which do not alter the chemical composition of a substance.
The match burning and leaving a charred stick of wood is a chemical change. This is because the chemical composition of the wood is altered during the burning process, causing a new substance (char) to be formed.
Tearing a tissue paper is a physical change because it involves a change in the physical state of the paper without altering its chemical composition. The other options, burning a match and baking a cake, involve chemical changes as they result in new substances being formed through chemical reactions.
Burning a match is not a phase change. A phase change refers to a physical change in the state of matter, such as melting, freezing, vaporization, or condensation. When a match burns, it undergoes a chemical change as the reactants (matchstick and oxygen) are transformed into new substances (carbon dioxide, water vapor, and ash) through a combustion reaction. This chemical change involves the breaking and forming of chemical bonds, rather than a change in the state of matter.
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
A match burning is a chemical change. Salt dissolving in water is a physical change.

This is different from physical changes, which do not alter the chemical composition of a substance.
Burning a match involves a chemical reaction where the match tip reacts with oxygen in the air to produce heat and light. This process involves both physical and chemical changes, as the match undergoes combustion to produce new substances such as ash and smoke.

Chemical, it isn't reversable.

Lighting A Match
Yes, lighting a match from a matchbox is a chemical change, not a physical change. When the match is struck, the chemicals on the match head react to produce heat, light, and a flame. This transformation is a chemical reaction, not just a change in physical state.
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
Mainly chemical (oxidation).
