The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Answer:
There are 12 sigma bonds and 3 pi bonds in benzene
Explanation:
- Molecular formula of benzene is
.
- Here six carbon atoms are joined together through alternative single and double bond forming a six membered cyclic ring.
- Six hydrogen atoms are attached to six carbon atoms through a single bond.
- A single bond represents a sigma bond. A double bond consists of a sigma bond and a pi bond.
- In the Lewis structure of benzene, there are three C-C single bonds, three C=C double bonds and six C-H single bond.
- Hence there are 12 sigma bonds and 3 pi bonds in benzene
- Lewis structure of benzene is given below
Answer:
0.06375 moles
Explanation:
Molarity is defined as moles of a solute per volume of solution.
-Given the molarity is 0.750m and the volume is 85ml
#Apply the molarity formula to solve for moles:

Hence, 0.06375 moles of sulfuric acid are needed.
The answer is: point- source pollution
