Standardization is the process of titrating a solution that is prepared from: a carefully measured solid mass to accurately find the concentration of titrant.

Titration is also known as volumetric analysis (titrimetry) and it can be defined as a chemical process in which a solution of known concentration (titrant) is carefully and slowly added to another solution of unknown concentration, so as to determine the concentration or quantity of the analyte.

Similarly, a process referred to as standardization is used to titrate a solution that is prepared from a carefully measured solid mass to accurately find the concentration of titrant.

24 hours

Explanation:

There are 24 hours in a day cause that is how long for the earth to spin on its axis

Answer:

24 hours

Explanation:

The time it takes Earth to rotate so the sun appears in the same position in the sky, known as a solar day, is 24 hours. However, the time it takes Earth to complete one full rotation on its axis with respect to distant stars is actually 23 hours 56 minutes 4.091 seconds, known as a sidereal day.

The patagium (plural: patagia) is a membranous structure that assists an animal in gliding or flight. The structure is found in living and extinct groups of animals including bats, birds, some dromaeosaurs, pterosaurs, gliding mammals, some flying lizards, and flying frogs.

A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees.

Answer:

patagium in American English

1. a wing membrane, as of a bat. 2. the extensible fold of skin of certain insects or of a gliding mammal or reptile, as a flying squirrel.

Explanation:

A prehensile tail pertains to the tail of certain animals that enable the latter to grasp or hold objects. ... A fully prehensile tail is one in which the animal can fully hold on to and manipulate an object with its tail.

Answer:

The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO2. Phenol red is yellow/orange under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6). This occurs when the concentration of CO2 is high.

Explanation:

is this correct

A phenol red-containing solution with low CO2 level will appear red.

Phenol red is a substance that serves as an indicator. It changes in colouration in response to the acidity or alkalinity of solutions.

In acidic solutions, phenol red turns yellow while the colour is red in basic solution.

Solutions with high CO2 levels are acidic while those with little to no CO2 concentrations are basic.

Thus, in a low CO2 solution, phenol red will turn red and the solution will generally appear red.

Answer:

Ocean tides are caused by the gravitational pull of the moon and the sun. The moon has the greatest effect on the tides. When the Sun, moon, and earth are in a straight line, we have Neap tides. When the Sun, moon, and earth are at right angles we have spring tides. Spring tides are especially high tides while neap tides are especially low tides.

Answer:

Once the parachute is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. ... The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.

When the skydiver is falling at a constant velocity after the parachute is open, acceleration is zero.

Because only certain size electron orbits are allowable, the frequency and energy of the electron is quantized

According to the Bohr model of the atom, an electron moves from a lower to a higher energy level when it absorbs energy. This energy is released when the electron returns to ground state.

According to the Bohr model, only certain size electron orbits are allowable hence the frequency and energy of the electron is quantized.

Answer:

we have to find the number of moles of NH₃ formed by reaction of 2 moles of N₂ and 2 moles of H₂. ... ∴ 2 moles of hydrogen will give = 1.33 moles of ammonia. therefore the no of moles of ammonia after the reaction would be 1.33 moles

Since the ethanol has a density of 0.800 g/mL, the mass of the ethanol is 180 grams.

Given the following data:

Volume of ethanol = 225 mL

Density of lead ball = 0.800 g/mL.

To find the mass of the ethanol;

Density can be defined as mass all over the volume of an object.

Mathematically, the density of a substance is given by the formula;

Density = Mass/Volume

Making mass the subject of formula, we have;

Mass = Density x Volume

Substituting the given parameters into the formula, we have;

Mass of ethanol = 180 grams.

Answer:

0.08 M

Explanation:

here...

1. water and a salt

2. Magnesium hydroxide reacts with HCl to produce a solution that is neutral.

3. titrant

4. 0.08 M

5. indicator

{quizlet: captncrun}

The concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M

From the question,

We are to determine the concentration of sodium hydroxide

The given reaction is

HCl + NaOH → NaCl + H₂O

This means

1 mole of HCl is required to completely neutralize 1 mole of NaOH

To determine the concentration of sodium hydroxide,

We will use the formula

[tex]\frac{C_{A}V_{A} }{C_{B}V_{B}} = \frac{n_{A}}{n_{B}}[/tex]

Where

[tex]C_{A}[/tex] is the concentration of acid

[tex]C_{B}[/tex] is the concentration of base

[tex]V_{A}[/tex] is the volume of acid

[tex]V_{B}[/tex] is the volume of base

[tex]n_{A}[/tex] is the mole ratio of acid

[tex]n_{B}[/tex] is the mole ratio of base

From the give information

[tex]C_{A} = 0.10 \ M[/tex]

[tex]V_{A} = 40 \ mL[/tex]

[tex]V_{B} = 50 \ mL[/tex]

From the balanced chemical equation

[tex]n_{A} = 1[/tex]

[tex]n_{B} = 1[/tex]

Putting the above parameters into the formula, we get

[tex]\frac{0.10 \times 40}{C_{B} \times 50} = \frac{1}{1}[/tex]

Then

[tex]C_{B} \times 50 = 0.10 \times 40[/tex]

∴ [tex]C_{B}=\frac{0.1 \times 40}{50}[/tex]

[tex]C_{B}=\frac{4}{50}[/tex]

[tex]C_{B}=0.08[/tex]

Hence, the concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M
