<u>Answer:</u> No crystals of potassium sulfate will be seen at 0°C for the given amount.
<u>Explanation:</u>
We are given:
Mass of potassium nitrate = 47.6 g
Mass of potassium sulfate = 8.4 g
Mass of water = 130. g
Solubility of potassium sulfate in water at 0°C = 7.4 g/100 g
This means that 7.4 grams of potassium sulfate is soluble in 100 grams of water
Applying unitary method:
In 100 grams of water, the amount of potassium sulfate dissolved is 7.4 grams
So, in 130 grams of water, the amount of potassium sulfate dissolved will be
As, the soluble amount is greater than the given amount of potassium sulfate
This means that, all of potassium sulfate will be dissolved.
Hence, no crystals of potassium sulfate will be seen at 0°C for the given amount.

Explanation:
The physical properties and the chemical reactivity of halogens are best investigated in several different compounds. Compounds of a substance gives us good knowledge about how they behave and exists in nature.
- Halogens are very reactive group of elements.
- Due to their high electronegativity, they are the most reactive on the periodic table.
- They tend to find one electron to complete their octet by all means.
- They favor reactions where they have easy access to electrons.
- When atoms combines, they have different chemical properties.
- When the molecules combine to form intermolecular bonds, it tells on their physical properties.
- The compounds of halogens is a very good way to investigate their chemical reactivity and physical properties.

Answer:
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Through his careful breeding of garden peas, Gregor Mendel discovered the basic principles of heredity and laid the mathematical foundation of the science of genetics.
