2) Draw the expanded structural formula of the following: a) CH3-CH=CH-CH3
b) CH3-CH2-O-CH2-CH3
c) C2H6
d) C4H8

What are the resulting coefficients when you balance the chemical equation for the combustion of ethane, c2h6? in this reaction, ethane is burned in the presence of oxygen (o2) to form carbon dioxide (co2) and water (h2o). (g)+(g)→(g)+(g)

If the density of water is 1.0 g/cm3, which of these materials would float in water, based on their densities? check all that apply. aluminum cork iron lead wax

If 1.8 l of water is added to 2.5l of a 7.0 molarity koh solution, what is the molarity of the new solution
