Answer:
1. iron(III) oxide
2. 8
3. 8
Explanation:
Know the naming rules
Reactants on left side products on right side
Answer: 0.424 J/g°C
Explanation:
For this problem, we would have to manipulate the equaiton for heat, q=mCT. Specific heat is the C in the equation. Since we are looking for specific heat, we manipulate the equation so that it says C=.

*I didn't know how to type in delta so I just wrote the word delta, but pretend you see a Δ.
Now that we have our equation, we can plug in our values and solve.

*Please ignore the capital A in the equation. It pops up every time I type in the ° sign.

The addition of magnesium chloride to the solution results in unaffected chemical equilibrium of the system. Thus, option A is correct.
The given chemical equation has been:

The reaction is reversible and can be converted back to the reactant with the increase in the product concentration. The equilibrium has been the condition when the concentration of products and reactants in the reaction are equal.
With an increase in products or reactants, there has been a corresponding chemical shift in the equilibrium.
The addition of Magnesium chloride in the solution, results in the dissociation of compound as:

The compound results in neither the increase of reactants, nor increase of product concentration in the acetic acid equilibrium.
Thus, the equilibrium of the system will remain unaffected by the addition of magnesium chloride. Thus, option A is correct.
