Consider these changes.
(a) hg(l)-> hg(g)
(b) 3o2(g)-> 2o3(g)
(c) cuso4*5h2o(s)-> cuso4(s)+5h2o(g)
(d) h2(g)+f2(g)-> 2hf(g)

at constant pressure, in which of the reactions is work done by the system on the surroundings? by the surroundings on the system? in which of them is no work done?

The following reaction shows the products when sulfuric acid and aluminum hydroxide react. al(oh)3 + h2so4 → al2(so4)3 + h2o the table shows the calculated amounts of reactants and products when the reaction was conducted in a laboratory. initial mass and yield sulfuric acid aluminum hydroxide initial amount of reactant 40 g 15 g theoretical yield of water from reactant 14.69 g 10.38 g what is the approximate amount of the leftover reactant? 11.73 g of sulfuric acid 10.33 g of sulfuric acid 11.12 g of aluminum hydroxide 13.67 g of aluminum hydroxide
