Explanation:
(A) Manganese salts give a grey borax bead test in reducing flame.
(B) From a mixed precipitate of AgCl and AgI, ammonia solution dissolves only AgCl due to the formation of [Ag(NH

Fluorine (F), Chlorine (Cl) and Iodine (I) are all found in the same group on the Periodic Table because they have similar physical properties. Since they are all Halogens, they have 7 valence electrons in their outer shell. In order to get a total of 8, they naturally combine with elements of the same isotope (itself), so D comes close to being correct, but it's not the best answer choice.
Answer:
It would be choice A and D
Explanation:
Heat from the water will conduct into the metal. Hope this helps!
The changes in different properties such as concentration etc will change if the pH experiences a change.

What is pH?</h3>
This is referred to the power of hydrogen and is a measure of the degree of acidity or alkalinity of a substance.
When pH changes, the concentration as well as other properties in this context.
