Question 8 of 30 1 point if a precipitation reaction occurs, what will be the products of the unbalanced reaction shown below? pb(no3)2(aq) + k2(s04)(aq) → solubility table o a. pbso4(aq) + kno: (s) o b. pbso4(s) + kno3(aq) o c. pbso4(s) + kno: (s) o d. no precipitate will form.

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. one of these isomers has a heat of hydrogenation of 101 kj/mol (24.1 kcal/mol), and the heat of hydrogenation of the other is 113 kj/mol (27.1 kcal/mol). match the heat of hydrogenation with the appropriate dihydronaphthalene.

If i can still dissolve more sugar into the solution at a certain temperature what would i call that solution

Using data from seismic waves, geologists have learned that earth’s interior is made up of several
