Which of the following notations would be the appropriate and final way to display the formula for magnesium chloride?
lana [24]
The answer IS letter C. For magnesium to pair with chlorine and be neutral, magnesium must pair with two chlorines. Magnesium is in column 2 which means it has two valance electrons to "give away." If it gives away its two valance electrons, it becomes a +2 cation. Chlorine readily accepts only one electron, and when it does it becomes a -1 anion. So what does this mean? Well, Magnesium Chloride is made up of 1 Mg atom, and 2 Chlorine atoms because it forms a neutral compound. Mg gives 1 electron to each Cl atom forming a +2 -2 neutral compound. The Mg bares a +2 charge after giving its two valance electrons away, and each Cl bares a -1 charge after taking an electron. Hence +2 -2, which is neutral. This is why the formula is MgCl2.

labwork [276]

Answer:

See explaination andd attachment

Explanation:

Treatment of aldehydes and ketones with a suitable base can lead to the formation of a nucleophilic species called an enolate that reacts with electrophiles. These C nucleophiles are useful for making new carbon-carbon bonds.

When the equation ZnS+O ZnO+SO isbalanced the coefficientof O is<br> 1, 5, 3,or2
Flauer [41]
<span>ZnS + O --> ZnO + SO

Okay so first you have to count up the number of elements on each side of the equation. Your objective is to have the same number of each element on both sides.

Left Side:
Zn - 1
S - 1
O - 1

Right Side:
Zn - 1
S - 1
O - 2

Since there are two oxygens on the right side, you have to add a coefficient of 2 to the oxygen on the left side. The coefficient tells us that that element or molecule is being multiplied by the value of coefficient. Since we're adding a coefficient of 2 to the oxygen on the left side, there are now 2 oxygens on that side. Because that is the same amount of oxygen as on the right, the equation is now balanced.

Your final equation should look like this: </span>ZnS + 2O --> ZnO + SO

In conclusion, the answer is 2.
