Answer:Robert Hooke, (born July 18 [July 28, New Style], 1635, Freshwater, Isle of Wight, England—died March 3, 1703, London), English physicist who discovered the law of elasticity, known as Hooke’s law, and who did research in a remarkable variety of fields.
Explanation:
In 1655 Hooke was employed by Robert Boyle to construct the Boylean air pump. Five years later, Hooke discovered his law of elasticity, which states that the stretching of a solid body (e.g., metal, wood) is proportional to the force applied to it. The law laid the basis for studies of stress and strain and for understanding of elastic materials. He applied these studies in his designs for the balance springs of watches. In 1662 he was appointed curator of experiments to the Royal Society of London and was elected a fellow the following year.
One of the first men to build a Gregorianreflecting telescope, Hooke discovered the fifth star in the Trapezium, an asterism in the constellation Orion, in 1664 and first suggested that Jupiter rotates on its axis. His detailed sketches of Mars were used in the 19th century to determine that planet’s rate of rotation.
The solutes dissolves in solvent results in the formation of a solution.
Those mixtures in which the components of mixture are uniformly distributed throughout the mixture are said to be homogeneous.
Those mixtures in which the components of mixture are not uniformly distributed throughout the mixture are said to be heterogeneous.
Those solutions whose concentrations are accurately known are known as standard.
Hence, a mixture of uneven distribution and easy separation is heterogeneous.
Answer:
The answer would be A
Explanation:
If more solvent is added, the solution becomes unsaturated because in principle it is capable of dissolving more solute.
Are you saying as a single replacement equation? If so then yes. You can find the answer in the activity series. Whichever element is higher than the other can be switched
Answer:
when soluble ionic reactants combine to form insoluble products.
Explanation:
Precipitation reactions are those reactions in which two soluble substances which are ionic in nature combine together forming insoluble salt. This insoluble salts is called precipitate and the reaction is called precipitation reaction. Precipitate is solid substance which is deposited at the bottom of the solution as insoluble material. This precipitate mostly formed in double replacement reaction.
