Is digestion a physical or chemical change?
Its a chemical change.
What mineral is an essential part of more than 100 enzymes and is involved in digestion?
zinc
What is the colour of zinc after when zinc granules react with hcl?
When zinc granules react with hydrochloric acid, the zinc dissolves to form zinc chloride and releases hydrogen gas. The color change is not significant, and the zinc itself does not change in color during this reaction.
What part of digestion involves a physical change?
mechanical digestion
What type of change that occurs in mechanical digestion?
By definition mechanical digestion is a physical part of digestion.
Is the dissolving of zinc in acid a physical or chemical change?
The dissolving of zinc in acid is a chemical change. This is because new substances are formed during the process, specifically zinc ions and hydrogen gas. It involves a chemical reaction between the zinc metal and the acid.
Is digestion a physical and chemical change?
a chemical change
Found in molecules that help the body digest proteins?
Enzymes, such as pepsin and trypsin, are found in the body and aid in breaking down proteins into smaller peptides and amino acids during digestion. These enzymes work by catalyzing chemical reactions to facilitate protein digestion in the stomach and small intestine.
Is a dissolving zinc in acid a chemical change or physical change?
Dissolving zinc in acid is a chemical change. It really isn't being dissolved, it is reacting with the acid to form new substances. For example, if you react zinc with hydrochloric acid, the products will be zinc chloride and hydrogen gas. The zinc seems to dissolve, but it is actually combining with the chlorine in the hydrochloric acid. Zn + 2HCl ---> ZnCl2 + H2
Is dissolving zinc in sulphuric acid is a chemical change?
Yes, the zinc reacts with th sulfuric acid to produce zinc sulfate and hydrogen gas.
Is digestion of a candy bar a physical change or chemical change?
Chemical property
When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
