Explanation:

Magnesium representation : 1s²2s²2p⁶3s².

therefore, to become Mg2+ ion Magnesium losses electron from its 3s orbital to form 1s²2s²2p⁶.

therefore option C is correct.

hope this helps you.

What is the molarity of 2.00 L of a solution that contains 14.6 g NaCl?

White raven [17]

Answer: The molarity of the solution is 0.125 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n}{V_s}$

where,

n = moles of solute

$V_s$ = volume of solution in L

moles of $NaCl$ = $\frac{\text {given mass}}{\text {Molar mass}}=\frac{14.6g}{58.5g/mol}=0.250mol$

Now put all the given values in the formula of molality, we get

$Molarity=\frac{0.250mol}{2.00L}=0.125M$

Therefore, the molarity of the solution is 0.125 M

How did satellite tracking allow biologists to study the green sea turtle?

Rasek [7]

<u>Answer:</u>

It helped biologists collect data on when and where turtles travel.

<u>Explanation:</u>

Green sea turtles need to be conserved so the biologist take help of satellites in order to track down green sea turtles.

The tracking of green sea turtles can be done by the help of satellites as satellites send a signal whenever these turtles come to surface of water to breathe which can then be used to prevent the turtles from getting caught by poachers.
