Answer:
Conversion factor is 6.022 ×10^23 molecules/mole.
Number of moles is 5.845 moles
Explanation:
We are given;
3.52 × 10^24 molecules
Required to determine the conversion factor\
We know that according to the Avogadro's constant;
1 mole of a compound contains 6.022 ×10^23 particles
Therefore, 1 mole of a molecular compound contains 6.022 ×10^23 molecules.
Thus, the conversion factor in this case would be 6.022 ×10^23 molecules/mole.
Such that; 3.52 × 10^24 molecules are equivalent to;
= 3.52 × 10^24 molecules ÷ 6.022 ×10^23 molecules/mole.
=5.845 moles
Thus, the conversion factor is 6.022 ×10^23 molecules/mole.
Number of moles is 5.845 moles
<u>Answer:</u> The net chemical equation for the production of acrylic acid is given below.
<u>Explanation:</u>
We are given two intermediate equations:
<u>Equation 1:</u> 
<u>Equation 2:</u> 
To get the net chemical equation for the formation of acrylic acid from calcium carbide, carbon dioxide and water, we multiply the first equation by a factor of '6'.
The equation becomes:
<u>Equation 1:</u> 
<u>Equation 2:</u>
Net chemical equation now becomes:
Hence, the net chemical equation for the production of acrylic acid is given above.

The permanent magnet in the loudspeaker is fixed close to a mobile electromagnet coil. The electromagnet is attached to a flexible material called cone (). Passing an electric current in the electromagnet causes it to vibrate due to the interaction with the permanent magnet.Uh hope this helped.
Henderson–Hasselbalch equation is given as,
pH = pKa + log [A⁻] / [HA]
-------- (1)
Solution:
Convert Ka into pKa,
pKa = -log Ka
pKa = -log 1.37 × 10⁻⁴
pKa = 3.863
Putting value of pKa and pH in eq.1,
4.29 = 3.863 + log [lactate] / [lactic acid]
Or,
log [lactate] / [lactic acid] = 4.29 - 3.863
log [lactate] / [lactic acid] = 0.427
Taking Anti log,
[lactate] / [lactic acid]
= 2.673
Result:
2.673 M
lactate salt when mixed with 1 M Lactic acid produces a buffer of pH = 4.29.
