Answer:
It changed from unsaturated to saturated solution
Explanation:
Before adding the spatula tip full amount, the solution was unsaturated, but as soon as the spatula tip full amount was added and couldn't dissolve, it became unsaturated because it could not dissolve any more solute having already dissolved it maximum number of solute
I believe that saponification is the process in which triglycerides react with a strong, inorganic base such as sodium hydroxide to produce carboxylate salt and glycerol. The process is the making of soap by reacting triglycerides with a strong base to form glycerol and soap. Soaps are sodium or potassium salts of long chain fatty acids. When triglycerides in fat/oil react with aqueous NaOH or KOH, they are converted into soap and glycerol.
Explanation:
Weight is 120 pounds and mass is 54 kg
The mass of an object is same everywhere. If we were on the moon, its mass will remain to be 54 kg.
Weight of an object is given by :
g is acceleration due to gravity on that surface
For moon, it is 1/6 the gravitational force on Earth, g = 1.63 m/s²
1 pound = 4.45 N
It means my weight is 533.78 N
On the surface of Moon is will be :
