Why do some scientists have concerns have regarding further increases in bio fuel production. giving chemical reasons explain why is is expensive to manufacture ethanol from cellulose than starch derived from maize (drawing parallels with the structure, bonding and breakdown of polysaccharides in animals).
If 2 new elements have been discovered and one is R, a new element from the family with 3 valence electrons and Z, a new element from the family with 6 valence electrons. Write the formula for the binary compound between element R and element Z.
