After some much needed rest, the committee wishes everyone the best for their studies!
Do Your Best and Be The Man! Or Woman...
Some dear encouragement for you...
Success don't belongs to people who quits but to those who despite failures, try again.
Think Thomas Edison...
He once said, "If we all did the things we are really capable of doing, we would literally astound ourselves".
In addition, he also once proclaimed," Many of life's failures are experienced by people who did not realize how close they were to success when they gave up."
The committee believes if you put in effort as "doing the things" need effort, you would be astounded by your own results.
Now, let's think Albert Einstein...
He majored in various Sciences which revolves mainly around our modern time Physics.
I know you want an example... Eg, Special Theory of Relativity.
"The most important thing is not to stop questioning."
That was one of his many quotes he left for humanity. Now ask yourself, have you stop questioning?
You stop questioning by mainly memorising your work.
Yes, memorising is good but understanding is better.
Ask yourself why are zinc oxides and aluminum oxides amphoteric?
We must know that amphoteric oxides can be both acidic or basic according to the conditions.
Take zinc oxides for example.
Zinc oxides react with sulphuric acid to form a salt, zinc sulphate, and water.
ZnO + H2SO4 → ZnSO4 + H2O
Zinc oxides also reacts with sodium hydroxide to form sodium zincate and water.
ZnO + 2NaOH → Na2 ZnO2 + H2O
Zinc oxides does react with both acid or alkalis and thus is amphoteric.
So let's recall...
Acidic oxides reacts only with alkalis to form salt and water only. (Oxides of non-metal, Carbon dioxide, CO2. Sulphure dioxide, SO2)
Basix oxides reacts only with acids to form salt and water only. (Oxides of metal or bases, sodium oxides,Na2O. Magnesium oxides, MgO)
Neutral oxides are also oxides of non-metals and they contain less oxygen than the corresponding acidic oxides. ( Carbon monoxide, CO. Nitrogen monoxide, NO)
Amphoteric oxides reacts with both acids or alkalis to form salt and water only.
Remember, understanding is better than memorising.
Why does pythagoras theorem states that ?
The Pythagorean Theorem is a statement about triangles containing a right angle.
The Pythagorean Theorem states that:
"The area of the square built upon the hypotenuse of a right triangle is equal to the sum of the areas of the squares upon the remaining sides.
According to the Pythagorean Theorem, the sum of the areas of the two red squares, squares A and B, is equal to the area of the blue square, square C.
Thus, the Pythagorean Theorem stated algebraically is:
for a right triangle with sides of lengths a, b, and c, where c is the length of the hypotenuse.
Be encouraged and go! Class Committee believes you can do it!
