There are__types of rock groups.

When the compound, Ba (C2H3O2) 2, is mixed with water, the Ba (C2H3O2) 2 is: soluble because compounds containing the C2H3O2 - ion are soluble in water insoluble because most compounds containing the C2H3O2 - ion are insoluble in water soluble

The rate constant is found to be 3.9 x 10-5 M-1 s-1. Calculate the rate of formation of ozone when the concentration of oxygen atoms is 3.0 x 10-14 molar and the concentration of diatomic oxygen is 1.3 x 10-14 molar.

Use the equation. How much SiCl4 is needed to produce 2.7 moles HCl? SiCl4 + 4 H2O - - > H4SiO4 + 4 HCl
