Suppose you have 5.00g of powdered magnesium metal, 1.00L of 2.00M potassium nitrate solution, and 1.00L of a 2.00M silver nitrate solution. a) Which one of the solutions will react with the magnesium powder? I don't understand how to go about answering t...

Calculate how many grams of FeSO4 . 7 H2O (MW = 278.02 g/mol) will be needed to prepare 1 mL of a 0.2 M FeSO4 solution? Am I right when I say we'd need

Calculate how many grams of FeSO4.7 H2O (MW = 278.02 g/mol) will be needed to prepare 1 mL of a 0.2 M FeSO4 solution? Is that .0304g?

Diethyl ether (also known as “ether”), C4H10O (l), is an organic compound that has long been used as a surgical anesthetic. The complete combustion of 1 mol of C4H10O (l) to CO2 (g) and H2O (l) yields ΔH °=-2723.7 kJ. a) Write a balanced equation for the...

Most fish need at least 4.00 ppm dissolved O2 for survival. (a) What is this concentration in M (assume the density of the solution is 1.00 g/mL)? (b) What partial pressure of O2 above the water is needed to obtain this concentration at 10. °C? The Henry’...

Oh, awesome! I got it now. Thank you so much for your help!

.0304g?

My bad, I just corrected my answer and got -279.3 kJ
