Answer:
24.5 g of NaCl
Explanation:
We begin from the balanced reaction:
3MgCl₂ + 2Na₃PO₄ → 6NaCl + Mg₃(PO₄)₂
If the sodium phosphate is in excess, then the limting reagent is the magnessium chloride.
We convert mass to moles:
20 g . 1mol / 95.2g = 0.210 moles.
3 moles of MgCl₂ can produce 6 moles of NaCl
0.210 moles of salt, may produce (0.210 . 6) /3 = 0.420 moles
Ratio of reactant is twice the product
We convert the moles to mass:
0.420 mol . 58.45 g/mol = 24.5 g
c the temperature is increased?5)
Answer:
In fact, the epicenter of a hypothetical earthquake is located at the point where the earthquake begins to break. The epicenter is just above the surface of 'our planet'. The epicenter is what we call immediately above the 'hypocenter' of the earthquake on the stage that said surface.
Explanation:
Ne is the smallest
B is the biggest
It goes (smallest to largest) : Ne, F,C,B
