The equation that should be used here is q = mC∆T, but you will need to know the specific heat (C) of the skillet, or at least know what it's made of so you can look it up.
Then, you plug in the values where q = 565,000 J; m = 4.05 lbx454g/lb = 1839 grams; and ∆T = Tf-19) and then you'd solve for Tf = final temperature.

The GMW of hydogen is 1 so that implies that there's 29 g of Cl within the given amount of HCl. You become aware of that 1/2 of the Cl is utilized in MnCl2 so, therefore, half of the Cl is within the gas Cl2. Your reply is d) 14.6g.
