Which of these charges has the greatest magnitude

Chemistry
1 answer:
Natalka [10]3 years ago
6 0

Answer:

magnitude means absolute value, so the one that is greastest, like |-7| and |4| even id |-7| is a negative number, but it is still the one farthest away from 0, so |-7| is greater than |4|.

That is the way to find the greatest magnitude, but because I don't know your numbers so I can not answer your question, but this is the way to solve for it.

HOPE THIS HELPS!!!!!!!!!( IF IT DOES <u><em>PLEASE MARK ME AS BRAINLIEST )</em></u>

A buffer is made that is .10M propanoic acid (pKa = 4.9) and .05M sodium propanoate. Calculate the pH.
inna [77]
PKa= 4.9 therefore ka= 10^-4.9=  1.259x10^-5

ka= \frac{[H^+][CH3CH2COO^-]}{[CH3CH2COOH]}

[CH3CH2COO^-]&#10;= 0.05
[CH3CH2COOH]= 0.10

Therefore 1.259x10^-5 = \frac{[H^+][0.05]}{[0.1]}
Rearrange the equation to make the concentration of hydrogen the subject.
Therefore [H^+] =  \frac{(1.259*10^-5)(0.1)}{0.05}

Therefore [H^+]= 2.513*10^-5

pH= -log [H^+] = -log(2.513*10^-5)= 4.59.

If a doughnut contains 1.8 moles of sugar (C6H12O6), how many sugar molecules are in a box of one dozen doughnuts?
barxatty [35]

Answer:

130.1 x 10²³ molecules of sugar  

Explanation:

One dozen = 12 donuts

1 doughnut = 1.8 moles of sugar

12 doughnut = (1.8 x 12) moles of sugar = 21.6 moles of sugar

1 mole of any substance contains Avogadro’s number (6.023 x 10²³) of molecules.

1 mole of sugar = 6.023 x 10²³ molecules of sugar

21.6 moles of sugar = (6.023 x 10²³ x 21.6) molecules of sugar  

                                 = 130.1 x 10²³ molecules of sugar
