Answer:
Condenser
Explanation:
A condenser is laboratory apparatus used to condense vapors — that is, turn them into liquids — by cooling them down. Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction(Wikipedia).
Condensers of of practical importance especially in synthetic organic chemistry and in separation science where vapours are often condensed and collected the substance is collected in pure form by distillation.
Total Pressure = A partial + B partial….
35+5+25 = 65.0 atm
Well you didnt give me enough information so i cant really answer your question
The required volume of 0.10M NaOH solution that student will add is 20 mL.
<h3>How do we calculate the volume?</h3>
Volume of any solution which is required to prepare buffer will be calculated by using the below equation as:
M₁V₁ = M₂V₂, where
- M₁ & V₁ are the molarity and volume of NaOH solution.
- M₂ & V₂ are the molarity and volume of HF solution.
On putting values, we get
V₁ = (0.1)(20) / (0.1) = 20mL
Hence required volume of NaOH solution is 20mL.

The electron dot diagram for an element shows the valence electrons for the element. Oxygen is in group 16/VIA, so it has six valence electrons. Draw the symbol for oxygen. Then place one dot at each side of the symbol.
