Using standard reduction electrode potentials, calculate standard free-energy change at 25°C for the following reaction: 3Cu(s) + 2NO3-(aq) + 8H+(aq) → 3Cu2+(aq) + 2NO(g) + 4H2O(l).​

1.milk of magnesia, a suspension of mg(oh)2in water, reacts with stomach acid (hcl) in a neutralization reaction. mg(oh)2(s) + 2 hcl(aq) −→ 2 h2o(l) + mgcl2(aq) what mass of mgcl2 will be produced if 5.49 g of mg(oh)2 reacts? answer in units of g. 2.what mass of hcl is required to completely react with 5.49 g of mg(oh)2? answer in units of g.
