Answer:
The deprotonated organic acid (RCO2-) and protonated organic base (RNH3+) go into the aqueous layer because Organic compounds that are neither acids or bases do not react with either NaOH or HCl and, therefore remain more soluble in the organic solvent and are not extracted.
Explanation:
Heat is the most important thing in the melting point of rock. Rock, melts when put into<span> 572 degrees Fahrenheit and 1,292 degrees Fahrenheit. Different types of rock may melt at different temperature because in the difference of their material. HOPED THIS HELPS YOU :)</span>
Plants obtain energy from the sun during photosynthesis and pass it along the food chain.
<h3>What is a model?</h3>
A model is a representation of reality. We use models to understand what the real situation of things is like.
Let us recall that plants are the producers in the ecosystem. Energy flow from plants to animals. Plants obtain energy via the reaction 6CO2 + 6H2O --->C6H12O6 + ATP. This energy is passed along the food chain as organisms feed on each other.

Answer:
0.6743 M
Explanation:
HC₂H₃O₂ + NaOH → NaC₂H₃O₂ + H₂O
First we <u>calculate how many NaOH moles reacted</u>, using the <em>definition of molarity</em>:
- Molarity = moles / volume
- moles = Molarity * volume
- 0.4293 M * 39.27 mL = 16.86 mmol NaOH
<em>One NaOH moles reacts with one acetic acid mole</em>, so <u>the vinegar sample contains 16.86 mmoles of acetic acid as well</u>.
Finally we <u>calculate the concentration (molarity) of acetic acid</u>:
- 16.86 mmol HC₂H₃O₂ / 25.00 mL = 0.6743 M
