Explain why the second is not defined by the length of the day.
olga2289 [7]
The day's length is not a settled unit of time.

The earth itself is jiggling around space, going on an amazingly slight bended way and the unrest is dialing down record of tidal movement and the moon moving possibly away.
The day's length changes amid the time and in addition about predictably or something to that effect, and extra hop second is added to the timetable.
The second is portrayed using different unrests of the cesium 133 particle at 0 Kelvin in light of the fact that isolated from quantum mechanics, it isn't at risk to coincidental segments.

Solid liquid gas or plasma. Solid would be ice cubes (frozen state), liquid would be the water inside of the glass, the gas would be when you take that same water and place it on a stovetop to bring to a boiling point. (Gas state) and finally the plasma state is when you your gas particles (from the gas state) if you heat the gas particles, they will turn to plasma.

: If a 250. mL sample of the above buffer solution initially has 0.0800 mol H2C6H5O7 - and 0.0600 mol HC6H5O7 2- , what would be
Jet001 [13]

Answer: New concentration of HC_{6}H_{5}O^{2-}_{7} is 0.23 M.

Explanation:

The given data is as follows.

     Moles of HC_{6}H_{5}O^{2-}_{7} = 0.06 mol

     Moles of H_{2}C_{6}H_{5}O_{7} = 0.08 mol

Therefore, moles of OH^{-} added are as follows.

    Moles of OH^{-} = 0.125 \times \frac{25}{1000}

                          = 0.003125 mol

Now, new moles of HC_{6}H_{5}O^{2-}_{7} = 0.06 + 0.003125

                     = 0.063125

Therefore, new concentration of HC_{6}H_{5}O^{2-}_{7} will be calculated as follows.

       Concentration = \frac{0.063125}{0.275}

                               = 0.23 M

Thus, we can conclude that new concentration of HC_{6}H_{5}O^{2-}_{7} is 0.23 M.
