no it is chemical
Yes, milk turning sour is a chemical change.
milk going sour is a chemical change because it can't be reversed. Most physical changes can be reversed for example snow melting is a physical change because it can freeze again.
chemical change
Both milk souring and iron rusting are chemical changes.
Yes, it is a chemical change (reaction) though it carried out by microorganisms (Lactic acid bacteria):Out of glucose through the Embden-Meyerhof-Parnas (EMP) pathway yielding two moles of pyruvate.glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2OIntracellular redox balance is maintained through the oxidation of NADH, concomitant with pyruvate reduction to lactic acid.Two steps in short formula:C6H12O6 --'EMP'--> 2 C3H3O3- + 2 H+ --'Reduct'--> 2 C3H6O3and in words:glucose -> 2 pyruvate (2-oxopropanoate) + 2H+ -> 2 lactic acid (2-hydroxypropanoic acid)
Milk turning sour is a chemical change.
why is milk turning sour during summers
Yes, milk turning sour is a chemical change.
No, it's a chemical property
yes See Is Sour Milk a physical or chemical change for more info
It is a chemical change because there is a chemical reaction occurring that is rotting the milk. An example of a physical change would be if the milk was evaporated or frozen.
milk going sour is a chemical change because it can't be reversed. Most physical changes can be reversed for example snow melting is a physical change because it can freeze again.
chemical change
Physical changes are like water turning into ice, they can be reversed. Chemical changes form a new substance. Soured milk can not be reversed, so it is chemical.
chemical because u cant change it back into fresh milk
chemical change
