Among these Options the Option B contains a Balance chemical equation. Equation is as follow,
<span>2Na </span>₍s₎<span> + MgF</span>₂<span> → 2NaF </span>₍s₎ <span> + Mg </span>₍s₎
There are two Na atoms (or moles) at right hand side and two at left hand side.
There are two F atoms (or moles) at right hand side and two at left hand side.
There is one Mg atom (or mole) at right hand side and one at left hand side.
There are many chemicals in seawater that make it salty. Most of them get there from rivers carrying so yes
Answer:
The d-block elements are all metals and most have one or more chemically active d-orbital electrons. Because there is a relatively small difference in the energy of the different d-orbital electrons, the number of electrons participating in chemical bonding can vary.
<span>None. Since it is dominant, both would have to show it to pass in on.</span>
