its D. burning coal in a furnace
What will result in a chemical change a evaperating alcohol into vapor b crying wood in the shed c burning coal in the furnace d melting in to obtain water?
c) burning coal in the furnace
What will result in a chemical change?
Anything that will create a new substance or change the chemical makeup of the substance. Burning, cooking, oxidizing, and other chemical reactions are examples.
Is the burning of phosphorus physical or chemical change?
Burning of anything is a chemical change. Combustion (burning) is a chemical reaction; it is simply where oxygen is added to, for example, an element, and turns it into an oxide. Burning phosphorus would result in phosphorus oxide. P + O2 --> P4010
Which action would result in a chemical change?
A new substance is produced. Bubbles are given off (fizzing), which shows that a gas has been produced. Color changes. Turbidity (cloudiness) heat/light given off. A sound is produced/an explosion occurs etc
Which of the following will result in a chemical change A melting ice to obtain water B evaporating alcohol into vapor C drying wood in a shed D burning coal in a furnace?
The answer is D ! (a) melting ice to obtain water - is changing waterfrom its solid form to liquid by heat. (b) evaporating alcohol into vapour - is changing alcohol from liquid to a gas. (c) drying wood in a shed - is simply allowing Amy moisture present in the wood to evaporate. In all three of these cases the original material remains chemically unchanged. in (d) burning coal in a furnace - the cellular structure of the wood is broken down by heat - the individual wood cells are destroyed, turning it from cellulose to carbon.
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
What is a chemical change in a plastic soda bottle A. Burning B. Freezing C. Cutting D. Crushing?
A. Burning. Burning a plastic soda bottle would involve a chemical change because the plastic molecules are being broken down and rearranged into different chemical substances. Freezing, cutting, and crushing would not result in a chemical change, as the chemical composition of the plastic would remain the same.
Example of result of chemical change?
something rusting, something burning. chemical changes can fool you because most of the time they change color and such. but if two substances mix to make a new substance than that is a chemical change.
Is the smoke from burning wood a chemical change?
No. You must not confuse the PROCESS of converting some chemical products to others, with the RESULT. The PROCESS of converting wood and oxygen to smoke is a chemical change. The SMOKE itself is not.
Why are burning wood and metal rusting classified as chemical change?
Both result in "new" substances (ash, smoke, rust).
Which of the following processes does not involve a chemical change in property A rusting B boiling C burning D fermenting?
Boiling does not involve a chemical change in property. Boiling is a physical change in which a substance changes from a liquid to a gas without changing its chemical composition. The other options (rusting, burning, fermenting) involve chemical reactions that result in changes to the chemical composition of the substances involved.
