Examine the chemical reaction. What coefficient of O2 should be added so the number
of atoms of oxygen is conserved on both sides of the
reaction equation?

C3H8 + O₂ + 4H₂O + 3C0₂

A 3
B 5
C 7
D 10

a) the particles of the chair are strongly held together.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
