It takes energy to ionize any atom. It takes progressively more and more energy for each successive electron that is removed and
IrinaVladis [17]

Answer:

Removal of Third Electron

Explanation:

a major jump is required to remove the third electron. In general, successive ionization energies always increase because each subsequent electron is being pulled away from an increasingly more positive ion.

Ionization energy increases from bottom to top within a group, and increases from left to right within a period.

Carol and Juan were playing with Carol's new train set. They pushed the trains around the track. They tried four different
Bumek [7]

Speed (m/s) = distance (metres) ÷ time (seconds)

For Track 1: 0.2 ÷ 2 = 0.1m/s

For Track 2: 0.2 ÷ 2 = 0.1m/s

For Track 3: 0.6 ÷ 6 = 0.1m/s

For Track 4: 0.4 ÷ 6 = 0.07m/s

The train on Track 4 had the slowest speed because it's got the shortest speed and it's covering less distance per second therefore it is slower.

A sample of the chiral molecule limonene is 79% enantiopure. what percentage of each enantiomer is present? what is the percent
Degger [83]

Answer :  The % of (+) limonene isomer = 79%


                The % of (-) limonene isomer = 0%


                The % of enantiomeric excess = 58%


Explanation :   Enantiomeric excess (ee) is the measurement of purity used for chiral substances.


Given,


% of pure limonene enantiomer = The % of (+) limonene isomer = 79%


Therefore, The % of (-) limonene isomer = 0%


Formula used :  

\%(+)\text{ isomer}=\frac{ee}{2}+50\%


Where,         ee → enantiomeric excess


Now, put all the values in above formula, we get the value of enantiomeric excess (ee).


     {ee}=\frac{\%(+)-50\%}{2}


            =\frac{79\%-50\%}{2}


              = 58%
