What is the charge on each of the following complex ions? hexaaquairon(ii), [fe(h2o)6]? tris(carbonato)aluminate(iii), [al(co3)3]? diaquatetrachlorovanadate(iii), [v(h2o)2cl4]? express the charges numerically, in the order that the complexes are listed, separated by commas. for a nonzero charge, be sure to include the sign (e. g., +1,-2,+3). view available hint(s)
the answer is pressure and temperature.
the law states that for an ideal gas, the pressure of a gas is directly proportional to the absolute temperature, at constant volume.
- it can be expressed as: (pi/ ti)v = (pf /t f)v
where, pi and ti are the initial pressure and temperature, pf and t f are the final pressure and temperature
- the letter (v) is written out of the brackets means that the volume is constant..
reaction type: synthesis hope this goodluck
δhrxn = [(1) x (-1675.7 kj/mole) + (2) x (0 kj/mole)] - [(1) x (-824.3 kj/mole) + (2) x (0 kj/mole)] = -1675.7 kj/mole + 824.3 kj/mole = -851.4 kj/mole.
explanation:to calculate δh of the reaction, we use the mathematical relation: δhrxn = ∑δhproducts - ∑δhreactants.so, δhrxn = [(n x δhf for al₂o₃) + (n x δhf for fe)] - [(n x δhf for fe₂o₃) + (n x δhf for al)]where n is the number of moles of each reactant.δhrxn = [(1) x (-1675.7 kj/mole) + (2) x (0 kj/mole)] - [(1) x (-824.3 kj/mole) + (2) x (0 kj/mole)] = -1675.7 kj/mole + 824.3 kj/mole = -851.4 kj/mole.δhf for al and fe = 0.0 kj/mole; since the heat for formation of elements that found in nature is equal 0.0 kj/mole
the measured amount of a product obtained from a chemical reaction is the actual yield
