Answer:
The periodic table of elements puts all the known elements into groups with similar properties. This makes it an important tool for chemists, nanotechnologists, and other scientists. If you get to understand the periodic table and learn to use it, you'll be able to predict how chemicals will behave.

Answer:
mass of the butter is 2.107 kg
Explanation:
specific gravity = destiny of the substance / density of
the water at 4°C
0.86 = density of the butter / 1000
where density of the water is 1000 kg/m^3 at 4°C
density of the butter = 860kg/m^3
now,
density of the butter = mass of the butter / volume
860 = mass of the butter / 2.45 × 10^-3
( 1 L = 10^ -3 m^3)
mass of the butter = 2.107 kg

Answer:
D- Assertion is false and Reason is true
Explanation:
Precipitation is said to have occurred when an insoluble product is formed from soluble ones. Let us take an instance;
BaCl2(aq) + H2SO4(aq) -------> BaSO4(s) + 2HCl(aq)
The barium sulphate so formed is an insoluble product obtained from the reaction of soluble barium chloride and sulphuric acid. This is a typical example of a double replacement reaction as the both ions exchanged partners.
Thus, the assertion is false but the reason is true.
