Is separating sand from water a chemical reaction?
No. It's a physical reaction.
Is cornstarch mixed with water a chemical reaction?
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.
Is separating oil and water a chemical reaction?
This is not a chemical reaction. When this happens it is clearly just called Chemical Seperation as the two chemicals do not bind due to density.
Is mixing calcium chloride and water a chemical reaction?
Yes. CaCl2(aq) + H2O(aq) = 2HCl(aq) + CaO(s), a double displacement reaction which forms a precipitate, therefore, is a chemical reaction.
Is separting sand from water a chemical reaction?
No, separating sand from water by filtration is a physical process, not a chemical reaction. This process involves passing the mixture through a filter to physically separate the solid particles from the liquid.
Why is separating water into oxygen and hydrogen chemical change?
Separating water into oxygen and hydrogen is a chemical change because it involves breaking the chemical bonds within the water molecule and forming new bonds to create the two separate elements. This process requires a reaction to occur, resulting in a chemical transformation.
Is sodium polyacrylate and water a chemical reaction?
No, mixing sodium polyacrylate with water is a physical interaction rather than a chemical reaction. The sodium polyacrylate absorbs the water, forming a gel-like substance, but no new chemical bonds are formed.
Is mixing water and baking soda a chemical or physical change?
chemical. when a reaction is undertaken that changes the structure of a substance and creates a new substance it is a chemical reaction. a gas is created during the reaction and a new chemical compound (sodium acetate) is left behind leaving neither of the previous elements present.
Is mixing hydrogen peroxide and sugar a chemical reaction?
Yes, mixing hydrogen peroxide with sugar can result in a chemical reaction. The hydrogen peroxide can oxidize the sugar, breaking it down into water and carbon dioxide, releasing energy in the process. This reaction can be exothermic and produce heat.
Why is mixing cool aid in water physical?
Mixing Kool Aid in water would be considered a physical rather than a chemical change, because the Kool Aid does not undergo any chemical reaction with the water, and it remains chemically identical to what it was before you mixed it into the water.
Is water a substance or a mixture Why did you say so?
water is a substance, made of oxygen and hydrogen, because mixing ox and hyd would give nothing but explosion, water is an effect of chemical reaction, not only mixing gases
Is the reaction between corn starch and vinegar a chemical reaction?
No, because it just change to liquid
