2. Still sleepy from a late night studying, you take the milk out of the refrigerator and pour it on your
lemon juice to milk to make paneer (fresh cheese). As a group, craft a chemical explanation for the fact
of coagulated milk onto your cereal. The last time you saw milk coagulate like that was when you added
breakfast cereal. Unfortunately, by the time you notice the funny smell you have already poured clumps
lemon juice to milk to make paneer (fresh cheese). As a group, craft a chemical explanation foea added
that spoiled milk coagulates.
