As milk spoils, the mass of lactose ( )

Question

. At the same time, the mass of lactic acid ()
. Because of this, the total mass inside the container ( )
as milk spoils.
1. decreases
2. increases
\3. does not change

Answer 1

As milk spoils, the mass of lactose decreases as it is converted into lactic acid through the process of fermentation. At the same time, the mass of lactic acid increases as lactose is broken down.

However, the total mass inside the container does not change during this process, as mass is conserved in a closed system.

So, the summarized statements are:

1. The mass of lactose decreases.
2. The mass of lactic acid increases.
3. The total mass inside the container does not change.
