A physical process is a process which do not change the substance structure only its shape or phase is changed. On the other hand, a chemical process involves the formation of new substances.
a. corrosion of aluminum metal = chemical process
b. Melting of ice = physical process
c. Pulverizing an aspirin. = physical processd. Digesting a candy bar. = chemical process
e. Explosion of nitroglycerin. = chemical process
f. Milk turning sour. = chemical process
g. Burning of paper. = chemical process
h. Forming of frost on a cold night. = physical process
i. Bleaching of hair with hydrogen peroxide. = chemical process
j. A copper wire is hammered flat. <span>= physical process</span>
The Answer is A
Hope this helped ;)
I am pretty sure the answer is F
A. Real gases may be expected to deviate from Charles's law at high pressures.
C. Real gases may be expected to deviate from Charles's law near the liquefaction temperature.
1. Direct Combination or Synthesis ReactionIn a synthesis reaction two or more chemical species combine to form a more complex product.
2. Chemical Decomposition or Analysis ReactionIn a decomposition reaction a compound is broken into smaller chemical species.
3. Single Displacement or Substitution ReactionA substitution or single displacement reaction is characterized by one element being displaced from a compound by another element.
