C6H6 is benzene, an organic compound. I would imagine it would be immiscible, since most organic compounds don’t dissolve in water very well.
Hey there!:
Molar mass MgCl2 = 95.2110 g/mol
So:
1 mole MgCl2 -------------- 95.2110 g
moles MgCl2 ---------------- 319 g
moles MgCl2 = 319 * 1 / 95.2110
moles MgCl2 = 319 / 95.2110
=> 3.350 moles of MgCl2
Hope that helps!
Answer: 238.6 J
Explanation:
1) Chemical energy is indicated as enthalpy
2) Energy balance:
∑ enthalpy of the reactants + energy added = ∑ enthalpy of the products + energy released.
3) ∑ enthalpy of the reactants = 85.1 J + 87.9 J = 173 J
4) energy added = 104.3 J
5) ∑ enthalpy of the products = 38.7 J + D
6) energy released = 0
7) Equation:
173J + 104.3J = 38.7 + D + 0
⇒ D = 173J + 104.3J - 38.7J = 238.6J, which is the chemical energy of the product D.
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. ... (a) Solid O2 has a fixed volume and shape, and the molecules are packed tightly together.

Answer:
Explanation:
Zn + 2HCl ⇄ ZnCl₂ + H₂
A system in equilibrium will try to annul any stress placed on the system for it to maintain the equilibrium position.
For reactions in which concentration changes are effected, the equilibrium shifts to the right if the concentration of species on the reactant side is increased and vice versa.
In the reaction above, if the concentration of the HCl is decreased, the equilibrium will shift to the left in order to increase back the concentration of both the Zn and HCl. Therefore, the acid HCl will become more acidic.
