♻️ REACTIONS OF FATS and OILS
It is worthy to note that apart from using Fats and oils in catalytic hydrogenation and saponification, fats and oils are eaten as food and they provide more energy than equal masses of carbohydrates.
1. Catalytic hydrogenation: This is the process of producing solid or hardened fat or margarine from liquid fat or oil(both liquids). This process converts the double bonds of unsaturated fatty acids to saturated fatty acids. This is done to prevent rancidity which may be caused by auto-oxidation of the food using double bonds as sites of reaction. To do this, hydrogen is added to the fat & oil (triglyceride) in the presence of nickel catalyst over a temperature of about 200°C.
Hardened oil or solid fat is gotten as the end product. This product is then treated with vitamins, salts, milks and flavourants to give margarine.✅
🔹 Catalytic hydrogenation is done to make natural fats and oils edible.
2. Saponification: This is the alkaline Hydrolysis of fats and oils using NaOH or KOH to yield propane-1,2,3-triol(glycerol) and soap. The glycerol formed of a trihydric alkanol with 3 -OH groups. "Glycerol formed is used in making paints✅✅"
🔹Hard soaps are produced if NaOH(caustic soda) is used. Hard soaps are used for laundry
🔹Soft soaps are produced if KOH(caustic potash) is used. Soft soaps are used for toilet soap and laundry.
👉👉Soaps are the sodium or potassium salts of fatty acids represented as RCOONa+ or RCOOK+
👉it is the alkaline Hydrolysis of fats and oils that is called saponification. The acid hydrolysis is not saponification. The acid hydrolysis produces glycerol and a mixture of saturated and unsaturated fatty acids. H2SO4 is used here. I dash you this one.

DT BREAKFAST QUESTIONS( English)✍😋🔥🤝
1. Choose the option that best best completes the gap(s).
Olu brought his clothes and those of his _.
A) senior brother's
B) elder brothers
C) elder brother's
D) senior brother
The correct answer is B.✍
It's "elder brothers", not "elder brother's." 'Those' is a pronoun referring to the clothes. Note that 'of' is serving a possessive function there. Thus, the phrase, "elder brother", cannot take the possessive " 's".
2. Choose the option that best completes the gap(s).
Everybody is allowed to _ his/her view on state matters?
A) air
B) hear
C) show
D) share
The correct answer is A.✍
To air your opinion is to make your idea, opinion or argument known.

DT Breakfast QUESTIONS (Physics) 💫🔥😋📍
1. What causes haloes (rings) around the sun or the moon?
a) Total internal reflection
b) Refraction of light
c) Reflection of light
d) Dispersion
Correct Answer: C ✍️
When the sun or the moon is seen through a thin veil of high clouds, haloes, i.e. rings, are seen. These are formed due to the reflection of light by the icy crystals present in the atmosphere. So, this is the cause of rings around the sun or the moon.
2. Why is the sequence of colors in the secondary rainbow reverse of that in the primary rainbow?
a) Refraction of light
b) Two internal reflection
c) Reflection of light
d) Dispersion
Correct Answer: B ✍️
The sequence of colors in the secondary rainbow is the reverse of that in the primary rainbow because a secondary rainbow is formed by two internal reflections of light in water droplets while a primary rainbow is formed by just one total internal reflection.

DT BREAKFAST 🥞 QUESTIONS (Chemistry) 💫🔥💥✍️
1. The ionization enthalpy and density increase in the group from top to bottom.
a) true
b) false
Correct Answer: B ✍️
Density increases with increase in atomic number due to the increase in mass per unit volume down the group and the ionization enthalpy decreases from carbon to stannum, for plumbum it is slightly higher than stannum. So the above statement is considered to be false.
2. Why hydrides of Germanium are known as _
a) silanes
b) germanes
c) stannum
d) plumbane
Correct Answer: B ✍️
The hydrides of carbon are called hydrocarbons alkanes, alkenes or alkynes, whereas the hydrides of silicon are called silanes and the hydrides of germanium are called Germanes the only hydrides of stannane and plumbum are stand and plumbane.

b) false
Correct Answer: B ✍️
Density increases with increase in atomic number due to the increase in mass per unit volume down the group and the ionization enthalpy decreases from carbon to stannum, for plumbum it is slightly higher than stannum. So the above statement is considered to be false.
2. Why hydrides of Germanium are known as _
a) silanes
b) germanes
c) stannum
d) plumbane
Correct Answer: B ✍️
The hydrides of carbon are called hydrocarbons alkanes, alkenes or alkynes, whereas the hydrides of silicon are called silanes and the hydrides of germanium are called Germanes the only hydrides of stannane and plumbum are stand and plumbane.

DT DINNER QUESTIONS (Chemistry)*👇😋🔥 ✨
1. Equilibrium is said to be obtained when
A. All reactants have been used up
B. There is no further change in temperature
C. The rates of forward and backward reactions are equal
D. All the products have been formed
*Correct Answer: C*✍
*STOT' EXPLANATION*💢
_Equilibrium is attained when the rate of the forward reaction is equal to that of the backward reaction in a *CLOSED* system. Here, the free energy change, ∆G, is also zero._
2. Which of the following processes is a physical process?
A. Electrolysis
B. Allotropic change
C. Hydrolysis
D. Corrosion
*Correct Answer: B*✍
*STOT' EXPLANATION*💢
_Allotropic change does not affect the chemical properties of the substance. It is the inter-conversion of the allotropes from one form to another.🌀

DT BREAKFAST QUESTIONS (Biology) ✍💢🤝🔥
1. The condition known as cretinism is caused by the deficiency of
A. Vitamin A
B. Insulin
C. Thyroxin
D. Vitamin C
CORRECT ANSWER: C✍
Under-secretion of thyroxine in infants results in a condition of stunted growth, retarded brain function known as cretinism. Under secretion of thyroxine in adult results in condition of mental and physical sluggishness as well as reduced metabolic rate, obesity known as myxoedema.
2. The type blood circulation in an organism with haemocoel is
A. double
B. dosed
C. single
D. open
CORRECT ANSWER: C✍
In closed circulatory system, blood is in direct contact with body cells within a cavity called haemocoel example includes spiders, crustaceans, and other arthropods.
