Only answers C and D would make sense in this question. Hope I helped please give brainiest!
Answer:
The answer is "Option C".
Explanation:
Given equation:
![2Na_20_2 (s)+S(s)+2H_2O \longrightarrow 4NaOH(aq)+SO_2(aq)](https://tex.z-dn.net/?f=2Na_20_2%20%28s%29%2BS%28s%29%2B2H_2O%20%5Clongrightarrow%20%204NaOH%28aq%29%2BSO_2%28aq%29)
![\to \Delta H^{\circ}_{rxn} (298\ K) = -610 \frac{kJ}{mol}](https://tex.z-dn.net/?f=%5Cto%20%5CDelta%20H%5E%7B%5Ccirc%7D_%7Brxn%7D%20%28298%5C%20K%29%20%3D%20-610%20%5Cfrac%7BkJ%7D%7Bmol%7D)
![\to Na_2O_2 \ Mass = 7.8 \ g\\\\ \to Na_2O_2 \ Molar \ mass = 78 \frac{g}{mol}](https://tex.z-dn.net/?f=%5Cto%20Na_2O_2%20%20%5C%20Mass%20%3D%207.8%20%5C%20g%5C%5C%5C%5C%20%5Cto%20%20Na_2O_2%20%5C%20Molar%20%5C%20mass%20%3D%2078%20%5Cfrac%7Bg%7D%7Bmol%7D)
Has been the reactant which is limited since the two experiments are equal to
for relationship between stress amounts.
![Na_2O_2, n =\frac{Mass of Na_2O_2}{Molar mass of Na_2 O_2}=\frac{7.8 \ g}{78 \frac{g}{mol}} =0.1 \ mol \\\\q=\Delta H^{\circ}_{rxn} \times n = \frac{ -610 \ kJ}{ 2 \ mol \ Na_2 O_2} \times 0.1 \ mol \ Na_2O_2= 30.5 \ KJ\\\\](https://tex.z-dn.net/?f=Na_2O_2%2C%20n%20%3D%5Cfrac%7BMass%20of%20Na_2O_2%7D%7BMolar%20mass%20of%20Na_2%20O_2%7D%3D%5Cfrac%7B7.8%20%5C%20g%7D%7B78%20%5Cfrac%7Bg%7D%7Bmol%7D%7D%20%3D0.1%20%5C%20mol%20%5C%5C%5C%5Cq%3D%5CDelta%20H%5E%7B%5Ccirc%7D_%7Brxn%7D%20%5Ctimes%20n%20%3D%20%5Cfrac%7B%20-610%20%5C%20kJ%7D%7B%202%20%5C%20mol%20%5C%20Na_2%20O_2%7D%20%5Ctimes%200.1%20%5C%20mol%20%20%5C%20Na_2O_2%3D%2030.5%20%5C%20KJ%5C%5C%5C%5C)
Limiting reactant =
![q=30.5 \ kJ \approx 30 \ kJ](https://tex.z-dn.net/?f=q%3D30.5%20%5C%20kJ%20%5Capprox%2030%20%5C%20kJ)
Reactant is the left side. 4+3=7

Answer:
Chemical differentiation
Explanation:
The process by which minerals crystallize out of magma is termed chemical differentiation. Some times, it is referred to as magmatic differentiation.
- Minerals have different properties and at certain environment, it comfortable for the settle out of magma.
- Some minerals can crystallize out at very high temperature.
- Some will form at medium temperature whereas, some are low temperature minerals.
- Based on the properties of the minerals in a melt, a minerals will differentiate at various temperature and pressure regimes.
