The answer will be D because the reaction is what's first(A) and then it is the product that comes out.
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.
Equilibrium occurs when forward and reverse directions of a reversible reaction occur at the same rate so there is no overall change in the amounts of reactants and products.
The stream mouth is where a waterway streams into a bigger waterway, for example, another stream, a lake, or a sea. A watershed limit, likewise called a seepage isolate, marks the external most point of confinement of a watershed. A watershed is a tract of land depleted by a waterway and its tributaries.
