Answer:
c. when the meniscus is between marks, estimate the reading to the nearest tenth of a division (ie, estimate to 0.01 mL if buret has 0.1 ml divisions)
Explanation:
When we put a liquid in a pipette, we can see that the surface of that liquid will have a curve. This curve is called the meniscus and it has the correct volume that an aqueous solution has. However, for this, it is necessary that the meniscus is observed at eye level and that its edges and center are clearly visible.
The correct matches are as follows:
<span>1. Na+ + Cl- → NaCl
</span>D. synthesis reaction<span>
2. CCl4 → C + 2Cl2
</span>A. decomposition reaction<span>
3. H+Cl- + Na+OH- → Na+Cl- + H2O
</span>B. exchange reaction<span>
4. ADP + P + E ATP
</span><span>C. reversible reaction
</span>
Hope this answers the question. Have a nice day.
This is the only option that correctly describe characterisitics of noble gases.
All noble gases have a unique atomic fingerprint.
All noble gases have valence shells with 8 electrons but Heilum has only 2 valence electrons.
And all noble gases do not easily react with other elements as they have their outermost shell completly filled so they are highly stable.
All noble gases emits different colored light when electrified.
The least dense layer of the earth is the crust.
