Explanation

 Hydroxylation of alkene can be carried out by  alkaline KMnO4. 

Hydroxylation refers to the addition of two hydroxyl (OH) groups across a carbon-carbon double bond in an alkene.

Cold, dilute, alkaline potassium permanganate (KMnO4) is a common reagent used for this reaction.

It reacts with the alkene to form a vicinal diol (a molecule with two hydroxyl groups on adjacent carbon atoms). 

Explanation

The human body contains traces of many elements, and approximately 99% of its mass is comprised of just six essential elements:

1. oxygen
2. carbon
3. hydrogen
4. nitrogen
5. calcium
6. phosphorus

Another five elements—

1. sulfur
2. potassium
3. sodium
4. chlorine
5. magnesium

Make up about 0.85% of the remaining mass, bringing the total of essential elements to 11

Explanation

The velocity of a photon is independent of its wavelength. 

The velocity of a photon is determined by the speed of light in a vacuum, which is a constant value (approximately 299,792,458 meters per second) and does not change based on the photon's wavelength or amplitude.

The speed of light is a fundamental constant of nature. 

Explanation

Asset means کوئی قیمتی یا فائدہ مند چیز - ایک طاقت یا فائدہ

Explanation

The condition where the male sexual cells develop earlier than female cells is called protandrous. 

Explanation

73.650 rounded up to one decimal place is 73.7.

When rounding up, if the digit to the right of the desired decimal place is 5 or greater,

You increase the digit in the desired decimal place by one.

Since 5 in the hundredth place is greater than or equal to 5, the tenths place digit (6) is increased to 7.

Explanation

Phosphorus is not among the top 10 most abundant elements in the Earth's crust.

Most abundant element in Earth crust is Oxygen.

Oxygen in the crust is (46. 1%).

The chemical formula of oxygen (dioxygen) is O2.
