Answer:
Organic compounds contain carbon
Organic compounds CAN be synthesized
Explanation:
When you burn a log in your fireplace you are converting c<span>ellulose into carbon dioxide and water.

Wood is made from cellulose. When wood burns, cellulose reacts with oxygen from the air and it forms carbon dioxide and water vapor.
The reaction of the combustion of glucose is as follows:
C₆H₁₂O₆ + 6O₂ = 6 CO₂ + 6H₂O
When wood burns, we notice that it slowly disappears because it passes into the mentioned gases. The ash that is created is part of the wood that did not burn.
A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions. ... It is known as the titrant.
Answer:
2,53x10⁻³ moles of NaOH
Explanation:
The reactions of a diprotic acid with NaOH are:
H₂X + NaOH → HX⁻ + H₂O + Na⁺
HX⁻ + NaOH → X²⁻ + H₂O + Na⁺
Where the complete first reaction gives the first equivalence point and the complete second reaction gives the second equivalence point.
The total volume spent of NaOH to reach the second equivalence point is:
7,00mL + 14,07mL = 21,07 mL = <em>0,02107L</em>
As molar concentration of NaOH is 0,120M, the moles used to reach the second equivalence point are:
0,02107L×(0,120mol/L) = <em>2,53x10⁻³ moles of NaOH</em>
I hope it helps!
