Answer:
300 mM
Explanation:
In order to solve this problem we need to calculate the line of best fit for those experimental values. The absorbance values go in the Y-axis while the concentration goes in the X-axis. We can calculate the linear fit using Microsoft Excel using the LINEST function (alternatively you can write the Y data in one column and X data in another one, then use that data to create a dispersion graph and finally add the line of best fit and its formula).
The <u>formula for the line of best fit for this set of data is</u>:
So now we <u>calculate the value of </u><u><em>x</em></u><u> when </u><u><em>y</em></u><u> is 1.50</u>:
Δ 1.36 (3H, d, J = 5.5 Hz)
<span>CH*3-CH(X)(Y) </span>
<span>δ 4.63 (1H, q, J = 5.5 Hz) </span>
<span>CH3-CH*(X)(Y) </span>
<span>Note: X anY can't have hydrogen attached, so they are probably O. </span>
<span>δ 3.32 (6H, s); δ 4.63 (1H, q, J = 5.5 Hz) </span>
<span>There is only C2H6O2 remaining, so this must be two CH3 groups; the attachment must be as an ether, and there must be two of them: </span>
<span>CH3-CH(OCH*3)2</span>
The first one is the 2Hg+.....
The second is the Ca+ 2H2O....
The third is the first one, H2 + Cl2...
And the last is Fe+ S= FeS
It was so easy
Good Luck
<span>Is it on the Activity 5? "drop it like a hot spot'' .
</span><span>In the activity "Drop it Like its "hot spot", it can be seen that the surface of the paper which is directly in contact with the test tube became wet considering that the paper represents the earth's crust and the water is the magma coming from the earth's . </span>
