Answer 1

Answer:

pls mark me brainlist pls

Explanation:

We have

\begin{gathered}\sf Atomic \; Number \begin{cases} \bf X = 16 \\ \bf Y = 12\end{cases}\end{gathered}

AtomicNumber{

X=16

Y=12

So,

They may be broken into Electronic configuration to find the modem

Element X = 2,8,6

Element Y = 2,8,2

Now

We may observe that the both element are divided or have three shells. They belong to third period

Now

According to the question

The element x will have electropositive ion and element Y will have the electronegative ion.

Chemical equation is

\sf Mg + S \longrightarrow MgSMg+S⟶MgS

Answer 2

Answer:

Here crystallization happens and solid potassium chloride will separate out. (Crystallization is a chemical solid-liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs)
