Answer:
a solution of acetic acid and sodium acetate
Explanation:
A buffer solution is defined as a solution which resist a change in pH when small quantity of a strong acid or a strong base are added. A buffer solution is made up of mixture of a weak acid and its conjugate base or a mixture of a weak base and its conjugate acid.
Acetic acid is the only option because it is a weak acid with a corresponding conjugate base, acetate. Unlike a solution of sulfuric acid and sodium sulfate in which the sulfuric acid is a strong acid which doesn’t qualify it to be a buffer solution. The remaining options have different acid compounds paired together which makes them invalid too.
Answer:
Dot structures make it easy to count electrons and they show the number of electrons in each electron shell.
Arrow and line diagrams show the spin of electrons and show every orbital.
Written configurations require minimal space and show the distribution of electrons between subshells.
Explanation:
Answer:
True
Ammonia reacts as a nucleophile with alkyl halides to give primary amines in a nucleophilic substitution reaction. Yields are often poor as the product, a primary amine, RNH2, is itself a nucleophile and can react with more alkyl
A nitrile is a compound that contains a –CN (cyano) functional group with a carbon-nitrogen triple bond. The simplest organic nitrile is CH3–CN and is called acetonitrile, which is a good solvent for organic reactions. ... Structurally diverse nitrile-containing compounds are present in many medicinal drugs.
B. People can use additional conservation tactics, like sometimes bicycling.
Explanation:
The use of bicycle to cover short distances would be good change in change in behavior that would enhance the conservational tactics in using fossil fuels.
Most hybrid cars still use gasoline. Although they have dualized energy sources.
- Driving hybrid cars more often will not curb the conservation drive for fossil fuel. It will increase more demand for it.
- Driving separate hybrid cars will not solve conservation issue of fossil fuels.
- Driving the car more is no efficient way to curb the reliance on fossil fuels.
The use of bicycles to cover maybe short distances will be a good approach to conserving more fossil fuels.
