If the compound has a molar mass of 156 g/mol, what is its molecular formula?
oksano4ka [1.4K]
I believe that the choices for this question are:
C2H4O2, C4H8O4 CH2O, C6H12O6 C3H6O3, C6H12O6 C2H4O2, C6H12O6 
 
The answer to this based on the molar masses given is:
C2H4O2, C6H12O6 
 
To prove calculate the molar mass:
C2H4O2 = 2*12 + 4*1 + 2*16 = 60
C6H12O6 = 6*12 + 12*1 + 6*16 = 180

Which of the following statements best describes why a chemical change is different from a physical change.
Butoxors [25]

Answer:

C) Chemical changes involve formation of a new substance while physical change only impacts appearance or form.

Explanation:

The obvious difference between a chemical change and physical change is that in a chemical change new substances are produced while in a physical change, the form of the compounds are altered.

  • Most phase changes are products of physical changes. Such changes are easily reversible.
  • In a chemical change, a new kind of matter is formed. It is accompanied by energy changes.
  • The process is not easily reversible.
