Curd is acidic in nature, because an acidic substance has less value of pH. A milkman adds a very small amount of baking soda to fresh milk. Why does he shift the pH of the fresh milk from 6 to slightly alkaline? Answer: By making the milk more alkaline, it takes more time to turn into curd.
<h3><u>Answer;</u></h3>
D. Process B, because it is a spontaneous process.
<h3><u>Explanation</u>;</h3>
- A spontaneous process is one that will occur without any energy input from the surroundings.
- A spontaneous reaction may involve an increase or decrease in enthalpy, it may involve an increase or decrease in entropy, but it will always involve a decrease in free energy that is a negative ΔG.
- Therefore; process B is spontaneous since it has a negative ΔG
Answer:
Freezing point depression is a property of solutions where the solute lowers the normal freezing point of the solvent.

We've been told that 3.0 parts of carbon will react with 8.0 parts of oxygen. So let's use grams to say that 3.0 grams of carbon will react with 8.0 grams of oxygen to produce 11.0 grams of carbon dioxide (we get 11.0 grams of CO2 because of the law of conversation of mass. So 3.0 + 8.0 = 11.0).
Now we want 2200 grams of CO2. So divide 2200 by 11 to get 200. The value 200 represents 1 part. Now multiply that by 3 (because we want to use 3 parts of carbon) and you'll get 200 * 3 = 600 grams of carbon to get 2200 grams of carbon dioxide.</span>
