Lydia and Damien should select the bottle of weak base with high molarity(M)

<h3>Further explanation</h3>

According to Arrhenius, Base is a compound which in water releases OH- ions

Electrolytes (acids or bases) with a small degree of ionization are classified as weak electrolytes

If two students, Lydia and Damien, select each bottle of a concentrated weak base, then a guide can be chosen to choose some of the solutions available in the lab :

  • Base compounds are usually known from their names ending in hydroxide suffixes such as NaOH, sodium hydroxide
  • The weak base will be partially ionized in water because the ionization degree is close to 0 or less than 1
  • If there is a Kb value (base ionization constant), then this shows the strength of the base. The greater the value of Kb, the greater the base strength
  • If there are some weak bases, then Lydia and Damien choose the highest concentration, usually indicated by the value of Molarity (M)

Because no choice solution is included, the weak base example is:

Ammonia (NH₃)

Aluminum hydroxide (Al (OH)₃)

Copper (II) hydroxide Cu (OH)₂

Mercury (II) hydroxide Hg (OH)₂

A solution is prepared by mixing 25.0 g H2O and 25.0 g C2H5OH. Determine the mole fractions of each substance.
Veronika [31]

Answer:

Mole fraction H₂O → 0.72

Mole fraction C₂H₅OH → 0.28

Explanation:

By the mass of the two elements in the solution, we determine the moles of each:

25 g . 1 mol/ 18g = 1.39 moles of water (solute)

25 g . 1 mol / 46 g = 0.543 moles of ethanol (solvent)

Mole fraction solute = Moles of solute / Total moles

Mole fraction solvent = Moles of solvent / Total moles

Total moles = Moles of solute + Moles of solvent

1.39 moles of solute + 0.543 moles of solvent = 1.933 moles → Total moles

Mole fraction H₂O = 1.39 / 1.933 → 0.72

Mole fraction C₂H₅OH= 0.543 / 1.933 → 0.28

Remember that sum of mole fractions = 1

The Development and Characterization of Carbon Nanofiber/Polylactic Acid Filament for Additively Manufactured Piezoresistive Sen
horrorfan [7]

Compared to carbon nanotube, carbon nanofiber (CNF) is a unique quasi-one-dimensional nanostructure with a lot of edges and flaws (CNT). Additionally, their low cost and wide availability make them a valuable nanomaterial for upcoming technology.

<h3>what are the development and characterization of Carbon Nanofiber for Additively Manufactured Piezo resistive Sensors?</h3>

In accordance with the semiconductor material's piezo resistive effect, diffusion resistance is used to manufacture piezo resistive sensors on substrates of semiconductor materials. The diffusion resistor is connected in the substrate in the form of a bridge, allowing the substrate to be employed directly as a measuring sensor element.

  • Carbon nanofiber/polylactic acid filament for fused filament fabrication (FFF) and additive manufacturing (AM) strain sensors was studied for the effects of production factors.
  • To investigate the effects of CNF weight fraction, extrusion temperature, and number of extrusions on sensor performance, a design of experiments (DOE) approach was used. In the initial extrusion, dry melt mixing was used to combine CNFs and powdered PLA material.
  • Through the DOE procedure, it was discovered that extruding CNF/PLA material for two complete extrusions at 185 °C resulted in material with material with material with dramatically improved electrical characteristics in comparison to unmodified material.
  • Piezoresistive dog-bone shaped sensors were made using the best manufacturing technique using three different sizes of 5.0, 7.5, and 10.0 wt% CNF/PLA filament.

pshichka [43]

Answer:

not valid

Explanation:

Expert judgment is a useful validation method to verify the reliability of an investigation that is defined as “an informed opinion of people with experience in the subject, who are recognized by others as qualified experts in it, and who can give information, evidence, judgments and assessments ”

After submitting an instrument for comparison to the consultation and expert opinion, it must meet two quality criteria: validity and reliability. The validity of content is often established based on two situations, one that concerns the design of a test and the other, the validation of an instrument subject to translation and standardization procedures to adapt it to different cultural meanings. It is here that the task of the expert becomes a fundamental task to eliminate irrelevant aspects, incorporate those that are essential and / or modify those that require it.

1.  You have 10 grams of HCl, how many moles of HCl do you have?  
Oxana [17]

Explanation:

36.5gm (Molar mass) = 1mole

1 gram = 1/36.5 mole

10grams =(1/36.5) x 10 moles

= 0.027 x 10 moles

=0.27moles
