M=f/a m=129000N/84m/s/s=1535.714286kg/m/s/s
The formula can be empirical because the subscripts are reduced to the lowest fraction.
To check if this formula is also the molecular formula we can check by obtaining the molar mass of the compound it is equal to the given molar mass. Thus
12*2 + 4*1 + 16 = 44 g/mol
this is ~equal to the given molar mass thus the given equation can be both empirical and molecular.
Answer:
answer is a since solute dissolve a solvent to give a solution
Answer:
Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird's presence and continues to travel through the wire instead of through the bird's body. A bird's body is not a good conductor of electricity.
