It's either obey the law of conservation of mass, causing new matter to be created or it is an execption to the law of conservation of mass.
a chemical reaction
No, mixing sugar and chocolate is not a chemical change. It's a physical change.
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Yes it is chemical because the sun is producing food by causing chemicals and substances
To call it an physical or chemical change, we first need to describe both of them briefly. A physical change is the one which does not change the chemical properties of a substance. A chemical change is the one which changes the chemical properties of a substance. Whether they can be recovered or not is not of importance here. So if you mean to dissolve some powder in hot water such that it does not make any reaction with water, then its a physical change. (Mixing flour or salt or sugar powder are examples) However if you put some powder in hot water which creates a reaction and the molecules of that powder are no longer the same, then it would be a chemical change. (Adding tiny sodium or potassium pieces to water are examples)
It is a chemical change
Adding sugar to cereal is a physical change because the sugar does not undergo a chemical reaction when mixed with the cereal. The sugar retains its chemical structure and properties, only altering the taste of the cereal.
Yes, as well as a chemical change. It clearly changes (white, granulated sugar and liquid to burned brown sugar and liquid to a sticky [and delicious] substance). It changes from a solution to a syrup!
Chemical changes in sugar, such as caramelization or combustion, typically require high temperatures (above the sugar's melting point) to break down the molecular structure of sugar. In the presence of oxygen, sugar can undergo combustion reactions that produce water and carbon dioxide as byproducts. Additionally, catalysts may accelerate these chemical changes in sugar.
Making ice cream from sugar and cream involves both chemical and physical changes. The mixing and freezing of the ingredients results in a physical change as the state of matter changes from liquid to solid. At the same time, the reaction between the sugar and cream, as well as any added flavorings, involves chemical changes that alter the composition of the ingredients.
Pulverizing sugar is a physical change because it does not alter the chemical composition of the sugar molecules. Grinding the sugar only changes its physical state by breaking it down into smaller pieces without creating any new substances.
Heating sugar is a chemical change because it causes the sugar molecules to break down into simpler forms, resulting in the caramelization of sugar. This process involves the rearrangement of atoms and the formation of new substances.
Yes, when sugar crystals are ground into smaller pieces, it is considered a physical change since the chemical composition of the sugar remains the same. The change in the size and shape of the sugar crystals is a result of physical forces acting on the substance, rather than a chemical reaction occurring.
physical change. When sugar is heated, it changes from a solid to a liquid state without changing its chemical composition.
Physical changes
Burning Sugar is a chemical change. Burning or oxidization is always a chemical change. The process takes in Oxygen and Sugar and outputs different compounds including water, carbon dioxide, carbon monoxide, and other carbon residue. Explanation 2: Chemical changes are changes in what things are made out of. Physical changes are like ice melting ice and liquid water are still water one is a solid but the other is liquid. steam is a gas but is still water. these changes do not change what water is.
Yes, dissolving sugar in water is a physical change. If you let the water evaporate, you the sugar will be left behind. Evaporation is a physical process, not chemical.-No, It is a Chemical change.
