Vinegar is an aqueous solution of acetic acid, ch3cooh. a 5.00 ml sample of a particular vinegar requires 26.90 ml of 0.175 m na
Fed [463]

  The molarity  of  acetic acid in the  vinegar is  0.94 M


 <u><em> calculation</em></u>

Step 1:  write  the balanced equation between CH3COOH  + NaOH

that is CH3COOH   + NaOH  →  CH3COONa  + H2O


step 2 :  find the moles of NaOH

moles  =molarity  x volume in L

volume in liters = 26.90/1000=0.0269 l

moles = 0.175 mol /L x 0.0269 L  =0.0047  moles  of NaOH


Step 3: use the mole  ratio to find moles of CH3COOH

that is the  mole ratio of  CH3COOH: NaOH is 1:1 therefore  the moles of CH3COOH is  =0.0047  moles


Step 4:  find the  molarity  of  CH3COOH

molarity = moles/volume in liters

volume in liter = 5.00/1000 =0.005 l

molarity  is therefore=0.0047 moles/ 0.005 l = 0.94 M

The solubility of acetanilide is 0.53 g in 100 mL of ice‑cold water, and 5.50 g in 100 mL of boiling water. What is the maximum
GrogVix [38]

Answer:

MPR=90,36%

Explanation:

The recrystallization is a purification process where the solid to purify is dissolved in an appropriated dissolvent and then, changing the conditions the solubility changes and that solid (that was in solution before) precipitates and form crystals.

In this case, for boiling water 5.50 g of  acetanilide could be dissolved and then cold the water, so the mass of crystals formed will be  

m_{crystal}=\left(5.5-0.53\right)g=4.97g

The maximum percent recovery is then

MPR=\frac{mass\ of\ solid\ recovered}{mass\ of\ solid\ disolved}\times 100\% = \frac{4.97g}{5.5g}\times 100\%=90,36\%

Will P and O2 share or transfer electrons?<br> P + O2 →P4,O10
padilas [110]

Answer:

They will share electrons .

Explanation:

When P and O2 reacts, they will share electrons as both of the elements are non-metals.

Only metal elements such as K , Na , Ca , etc. can transfer electrons to the other non-metal elements.
