The pH of milk lowers as it turns into curd due to the formation of lactic acid.

Fresh milk is considered to be slightly acidic, having a pH lower than 7. Milk is converted into curd, the thickened or solid part of milk after the milk sours, through the process of fermentation. The lactic acid bacteria, such as Lactobacillus, converts lactose or the sugar present in milk into lactic acid, causing the milk to taste sour. The increase in the concentration of lactic acid results in the increase of hydronium ions which lowers the pH of the milk.

Answer:

ork out which of the displacement (S), initial velocity (U), acceleration (A) and time (T) you have to solve for final velocity (V).

If you have U, A and T, use V = U + AT.

If you have S, U and T, use V = 2(S/T) - U.

If you have S, U and A, use V = SQRT(U2 + 2AS)

when the following redoc reaction is balances (assume acidic solution), how many moles of water appear and on what side
PolarNik [594]

8 moles of water on the right side.

An oxidation-reduction or redox reaction is a reaction that involves the transfer of electrons between chemical items (the atoms, ions, or molecules involved in the reaction).

Redox reactions: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction.

Step 1:

MnO4- ----> Mn2+

2Cl- ------> Cl2

Step 2:

MnO4- --> Mn2+ + 4H2O

2Cl- -----> Cl2

Step 3:

8H+ + MnO4- ------> Mn2+ + 4H2O

2Cl- ----->Cl2

Step 4:

8H+ + MnO4- +5e- ------>Mn2+ + 4H2O

2Cl- ----> Cl2+ 2e-

Step 5:

16 H+ +2 MnO4- +10Cl- ----->2 Mn2+ + 8H2O+5Cl2

This is the balanced equation in an acidic medium.

That is 8, right side.
