Answer:
The chemical formula for the molecule is
Explanation :
Molecular formula : It is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Structural formula : It is a formula in which the lines are used between the bonded atoms and the atoms are also shown in the structural formula.
In the structural formula, the lines are used between the atoms.
As per given information of compound we conclude that, there are 4 carbon atoms, 9 hydrogen atoms and 2 oxygen atoms.
Thus, the chemical formula for the given molecule will be,
B. Circulatory, respiratory, nervous
Here it is the use of vector and conservation of momentum !
so,
√(16^2+21^2) ×1000= 3000 v
v =8.8 m/s
so answer is B !
if you have any doubt, you can ask ! just comment !
