<u>Answer:</u>
<u>Explanation:</u>
Frozen water is known to have more volume, but less density. When water slowly gets unfrozen, it'd volume decreases and its density increases. Hence, when the water gets unfrozen, it's volume decreases.
Answer:
The collection of fossils and their placement in chronological order is known as the fossil record

According to Avogadro's Law, same volume of any gas at standard temperature and pressure will occupy same volume. And one mole of any Ideal gas occupies 22.4 dm³ (1 dm³ = 1 L).
Data Given:
n = moles = ?
V = Volume = 16.8 L
Solution:
As 22.4 L volume is occupied by one mole of gas then the 16.8 L of this gas will contain....
= ( 1 mole × 16.8 L) ÷ 22.4 L
= 0.75 moles
Result:
16.8 L of Nitrogen gas will contain 0.75 moles at standard temperature and pressure.
The compound that is most likely present when treated with bromine and the sample absorbs the red bromine color is ; Cycloheptene
<h3>What is cycloheptene </h3>
Cycloheptene is an unsaturated colorless oily liquid which is insoluble in water it absorbs Bromine when used in performing unsaturation test due it unsaturated nature.
The red bromine color will be absorbed when used to treat Cycloheptene but will not be absorbed when used to treat cycloheptane due to its saturated nature.
Hence we can conclude that the compound that is present is Cycloheptene.
