Answer:

when the pH increases suddenly in the flask

Explanation:

I think it's right. :)

When the pH increases suddenly in the flask at that point is a base no longer added during a titration.

Titration is a typical quantitative chemical analysis procedure used in laboratories to quantify the concentration of a specified analyte. The titrant or titrator is a reagent that is produced as a standard solution with a known concentration as well as volume.

The pH scale, which originally stood for "potential of hydrogen," is used to describe the acidity as well as basicity of aqueous solutions. The pH of acidic solutions is lower than that of basic as well as alkaline solutions.

Answer:

2 L

Explanation:

Divide the mass by the concentration to find the volume.

(6 g)/(3g/L) = 2 L

According to the concept of solubility, in order to make solution of sugar the total volume of solution is 2 g/L.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

In order to calculate total volume of solution divide mass/ concentration that is 6/3=2 g/L.

Thus, the total volume of the solution is 2 g/L.

Answer:

The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m )

Curve amplitude : This is the maximum value of the radial velocity curve

Radial velocity shape ; The shape of Radial velocity curve is parabolic in nature

Orbital period : Orbital period is the time taken by the star  to make one complete rotation in its orbit

Explanation:

The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m ) while Curve amplitude  is the maximum value of the radial velocity curve also The shape of Radial velocity curve is parabolic in nature. and  Orbital period is the time taken by the star  to make one complete rotation in its orbit

The correct option is option A. when the students check the air pressure of bicycle tires, once by keeping it out in the winter and noticing the air pressure being decreased and after by keeping the bicycle inside at room temperature and noticing that the air pressure has increased.

According to Gay lussac's law, the temperature and pressure of a gas are directly proportional to each other, provided the volume is constant.

When the temperature of a gas is increased, the molecules gain more kinetic energy and hence the frequency of them hitting the walls of the container increases which basically implies that the pressure increases.

On the other hand when the temperature is low, the molecules do not have substantial kinetic energy to hit the walls of the container frequently, that is the pressure decreases.

When the bicycle tires were kept out in the winter, the low temperature decreased the air pressure inside the tires. While when they were warmed at room temperature, the pressure inside the tires increased.

Therefore, the correct option is option A.  when the students check the air pressure of bicycle tires, once by keeping it out in the winter and noticing the air pressure being decreased and after by keeping the bicycle inside at room temperature and noticing that the air pressure has increased.

Explanation:

Hello! Here's the answer I was able to come up with:

Why does Na have only one dot?

Sodium, or Na, has only one valence electron.  (This makes the atom tend to participate in ionic bonding and "give" its single valence electron to an atom like chlorine.)

Why do none of these diagrams show more than 8 dots?

It is physically impossible for an atom to have more than 8 electrons in its valence layer, according to the Octet Rule.

What relationship do you notice between the dots in these two charts?

The dot diagram for each element represents the number of electrons each element will have in its outermost, or valence, shell. (2-8-8)

The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why?

An atom can have a maximum of two electrons in its innermost layer. Hydrogen and helium have only one and two electrons, respectively, so they don't have enough electrons to actually have more than one layer. Therefore, their outermost layer is, in fact, their only layer. This is why the number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table.

Answer:

Q = 19065.4 J

Explanation:

Q₁ = the required energy for phase change of H₂O from vapor to liquid

Q₁ = mass of H₂O * heat of vaporization

Q₁ = 7.58 g * 2260 J/g

Q₁ = 17130.8 J

Q₂ = energy required to cool the water fro 101°C to 40°C

Q₂ = mass of H₂O * specific heat of H₂O * ΔT

Q₂ = 7.58 × (4.184 J/gC) × (101 - 40)

Q₂ = 1934.6 J

Q = Q₁ + Q₂

Q = (17130.8 + 1934.6) J

Q = 19065.4 J
