THIS IS AN COMBINATION REACTION SO3 Combined with H2O to form Sulfuric acid
The mass of this much chain is 0.22 grams for 7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car.
<h3>What are weight and mass?</h3>
Mass is the amount of the substance and object and the weight is the gravitational force required to act upon the particular mass of the substance.
To calculate the mass of car divide the wight to the gravity value 9.8 meter per second.
mass = weight / gravity
substituting the value,
mass = 2.16 / 9.8
mass = 0.22 grams
Therefore,7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car the mass will be 0.22 grams.

Answer:
Weak bonds require less energy to form than strong bonds
Explanation:
According to Coulomb's law, the force between two species is inversely proportional to the distance between them. That said, the bigger the atoms are, the greater the bond length should be to form a molecule.
As a result, for a greater bond length, the attraction force is lower than for a shorter bond length. This implies that large atoms would form weak bonds and small atoms would form strong bonds.
Bond energy is defined as the amount of energy required to break the bond. If a bond is weak, it would require a low amount of energy to break it. This is also true for energy of formation, as it's the same process taking place in the opposite direction.
According to Arrhenius theory, acid is a substance that releases H⁺ ions when dissolved in water.
In order to apply this theory, the substance must be soluble in water.
H₂SO₄ is highly soluble in water. It undergoes following dissociation reaction when dissolved in water.
From the above equation, we can see that H₂SO₄ forms 2 H⁺ ions when dissolved in water. Therefore it behaves as an acid according to Arrhenius theory.
