Answer:
Explanation has been given below.
Explanation:
- A buffer consists of either of a weak acid along with it's conjugate base or a weak base along with it's conjugate acid.
- Let's consider a buffer consists of a weak acid along with it's conjugate base
- If we add an acid to this buffer then conjugate base gets protonated and converted to corresponding weak acid. So effect of addition of acid gets neutralized by forming weak acid rather than increase in concentration of proton in solution.
- If we add a base to this buffer then weak acid gets converted to corresponding conjugate base. So effect of addition of base gets neutralized by forming conjugate base rather than in crease in concentration of hydroxyl ion in solution.

Explanation:
Hello!!
Please remember that density=mass/volume.
In this case, we have the same mass for the feathers and the gold (1 pound).
So, if the mass is the same for both we have:
Df*Vg=Dg*Vf where f means feathers and g means gold.
In this case we see density is inversely related to volume. Both materials have the same mass. So which one have a bigger volume?
For this take a pound of feathers and submerge in a known volume of water. Note the displacement. Do the same for a pound of gold. Whichever has the smaller displacement, has the greater density.
In this case, Gold has the greatest density.
Answer:
The most consistent mechanism is SN1.
Explanation:
The solvolysis of tert-butyl iodide in methanol will arise by the SN1 mechanism.
The reason for that is due the geometric structure of tert-butyl. The tertiary structure allows the formation of a stable carbocation, after the loss of the iodide ion. The carbocation will then be attacked by methanol molecules forming an eter.
The answer for the following question is explained below.
The option for the following answer is "d".
Explanation:
The phlogiston theory of combustion:(Greek word phlogiston means <u><em>"BURN"</em></u>)
Phlogiston theory states that phlogisticated substances are the substances that contain phlogiston and dephlogisticate when burned.
Dephlogisticating is the process of releasing stored phlogiston,which is absorbed by the air.
Growing plants then absorb this phlogiston,which is why air does not spontaneously combust and also plant matte burns as well as it does.
The prevailing theory was that flammable materials contained a substance called phlogiston that was released during the combustion.
For example:
- phlogiston was transferring into the surrounding air.
