Question

X is a substance which combines chemically with impurities associated with Ore to form easily fusible mass Y. find X and Y

Answer 1

X and Y will be following :
X - Flux
Y - Slag

Answer 2

Answer:

The substance $X$ is flux and $Y$ is slag.

Explanation:

• When we extract the metal from its ores and the metal is then modified so that it comes in a usable form, this process is termed metallurgy.
• A mineral that has a high concentration level of a particular metal and metal can be profitably extracted from it, that mineral can be termed as an ore.

We know that gangue is the impure waste present in the ore. Flux is a chemical substance that combines with impure waste to form a slag that can be easily removed.

$Gangue + Flux=Slag$

So, the substance $X$ is flux and the fusible mass $Y$ is slag.
