Answer:
H3C—CH3
Explanation:
The strength of a bond is indicated by the value of its bond dissociation energy. Simply put, the bond dissociation energy is the energy required to break the bond.
Carbon forms single, double and triple bonds with itself. As a matter of fact, carbon atoms can link to each other indefinitely. This is known as catenation and has been attributed to the low bond energy of the carbon-carbon single bond.
The bond energy of the carbon-carbon single bond is about 90KJmol-1 while that of carbon-carbon double bond is about 174KJmok-1. The carbon-carbon triple bond has the highest bond dissociation energy of about 230KJmol-1.
Hence, it is easier to break carbon-carbon single bonds than double and triple bonds respectively, hence the answer.
Answer;
Taxes
A disadvantage of corporations is that shareholders have to pay taxes on profits.
Explanation;
A corporation or public corporation is a form of business unit that is a legal entity, which in usually organized under the laws of a state, and whose investors or share holders purchase shares of stock as evidence of ownership in it.
One of the disadvantages of corporation is double taxation; A corporation may pay taxes on its income, after which the investors or the shareholders pay taxes on dividends earned, and therefore it means the income has been taxed twice.
Dissolving salt into water is a physical change. The salt is still salt & the water is still water. Nothing new is made. Although the salt is dissolved into the water & makes it salty, they are still two different entities.
Hope that helps!
Answer:
the particles of the rock possess kinetic energy as they stay in a place the particles also contain potential energy due to their position and arrangement This form of stored energy is responsible for keeping the particles together

Answer:
Polymerase Chain reaction is a method used by scientists to making A LOT (millions to billions) of copies of a DNA sample which then allows scientists to take a small of that DNA and increase the amount to a very large amount to study the DNA into further detail.
