Is cornstarch a chemical or a physical change when vinegar is added?
When vinegar is added to cornstarch, it undergoes a physical change. The vinegar interacts with the cornstarch molecules, causing them to form a non-Newtonian fluid, which changes the physical properties of the mixture.
What kind of bonding is created by the chemicals in cornstarch?
The chemicals in cornstarch, primarily amylose and amylopectin, form hydrogen bonds. These hydrogen bonds create a network that gives cornstarch its thickening properties when mixed with liquids.
What is the chemical formula for cornstarch added to water?
Well, there is no chemical reaction, really, since the cornstarch still remains cornstarch. (and if you dry it, it becomes cornstarch again) It's just that the cornstarch lightly bonds to the water which then lightly bonds to other cornstarch, creating a net-like substance. This net is easily broken and made, thus increasing the viscosity of the fluid and adding some other interesting properties to it as well.
What states of matter is gooey cornstarch in?
Gooey cornstarch is in a non-Newtonian state of matter called a suspension, in which the cornstarch particles are suspended in a liquid (typically water). This mixture has properties of both a solid and a liquid, exhibiting characteristics of both states of matter depending on the force applied to it.
Can we separate the cornstarch from water without using filter paper why?
Yes, cornstarch can be separated from water without using filter paper by employing techniques such as sedimentation or centrifugation. When mixed with water, cornstarch forms a suspension, and allowing it to sit can cause the heavier particles to settle at the bottom. Alternatively, centrifugation can rapidly separate the cornstarch due to its density. Both methods utilize the physical properties of the materials rather than filtration.
Is arrowroot the same as cornstarch?
No, arrowroot and cornstarch are not the same. They are both used as thickeners in cooking, but they come from different plants and have slightly different properties.

Is cornstarch magnetic?
No, cornstarch is not magnetic. It is a carbohydrate derived from corn and does not possess any magnetic properties. While some substances may exhibit weak magnetic behavior under certain conditions, cornstarch does not respond to magnetic fields.
How much cornstarch to use for 1 tables spoon of gelatine?
To substitute cornstarch for 1 tablespoon of gelatin, use about 2 tablespoons of cornstarch. Keep in mind that cornstarch acts as a thickening agent rather than a gelling agent, so the texture of the final product will differ from that made with gelatin. Additionally, you'll need to mix cornstarch with cold water before heating it to activate its thickening properties.
What is a suitable potato starch substitute for cornstarch in cooking and baking recipes?
Arrowroot powder is a suitable substitute for cornstarch in cooking and baking recipes. It has similar thickening properties and can be used in equal amounts as a replacement.
What can you use in the place of gumbo file?
there is no substitution. If you are using it fir its thickening properties, try a roux, cornstarch or arrowroot

What are the physical changes in flour?
the physical properties of flour are the bulk density, wettability and dispersibility.
What happen the sulfur when shake into cornstarch?
When sulfur is shaken into cornstarch, the sulfur particles become dispersed within the cornstarch granules. This mixture does not undergo a chemical reaction; instead, it forms a physical blend where the sulfur may affect the properties of the cornstarch, such as its flowability or texture. The resulting mixture can be used in various applications, like in certain types of powders or as an ingredient in chemical reactions. However, the sulfur itself remains chemically unchanged in this process.
