Question

When substance ‘P’ is added to substance ‘Q’, the substance ‘R’ is formed with same properties that is shown by either substance ‘P’ or by substance ‘Q’. But when substance ‘P’ and substance ‘R’ are heated together , they form a new substance ‘S’ whose properties are extremely different from P and Q. Identify ‘R’ and ‘S’ and also give an example of substance ‘R’ and ‘S’ from your everyday life.​​

Answer 1

Answer:

Since the substance R is a mixture of two substances, it may either be a mixture or a compound

In a mixture the constituents retain their properties while in a compound, they lose their properties.

Since the question mentions that R has different property from both P and Q, hence it must be a compound.
