Colas are also carbonated beverages. The carbonation can produce some carbonic acid in the  Cola, which would affect your results. Therefore, to ensure that you are only titrating the  phosphoric acid you will use de-carbonated soda. This can easily be obtained by gently  heating the soda, or as you may already know, by rapidly shaking the bottle. It is also important that we do not use diet Colas since the artificial sweeteners that they contain have  acidic functional groups that will also interfere with the titration.

Use a 25.00-mL pipet to deliver exactly 25.00 mL of room temperature, de-carbonated

Cola into a 250-mL beaker. Check out a magnetic stir bar and gently add it to the

beaker. Place the beaker on a stir plate. Set up a pH meter so that the probe is   completely immersed, but in a way that the stir bar will not hit it. The tip of the probe

has a thin glass membrane. Handle it with care! Position the beaker so that the stir bar

is as close to the center of the beaker as possible for optimal stirring. It should stir

rapidly enough to ensure thorough mixing but not so rapidly as to cause splattering.

__________________________________________________________

Obtain about 75 mL of 0.0100 M NaOH in a beaker. Use this NaOH to fill a buret.

Remember that you should always rinse a buret 2-3 times with the solution that you are

about to put into it and remove air bubbles at the buret tip. If you do not remember how

The initial level of the NaOH should be at exactly

0.00 mL. Once the buret is ready, place it over the beaker containing the Cola

Opinion and  and factless ideas  are not science and engineering practice as these are based on observations.

Observations are defined as a set of statements or facts which are recorded while conducting an experiment.Observations are made through sensing changes in the variables of the experiment.

It is specifically defined as an act of knowing or recording the changes in the variables of the experiment.Recording observations holds importance as recording observations avoid the experiment to be repeated over and over again.

It is important to note down observations so that the testing of hypothesis is made easier.There are four types of observations .Observations need to be descriptive and must be written in complete sentences and should include all the numerical data of the experiment.

Sample Response: No, thermal energy is not being transferred by radiation in this image. The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame, so this is conduction, not radiation. Radiation transfers thermal energy by electromagnetic waves, not by direct contact.

Explanation:

No, thermal energy is not being transferred by radiation in this image.

The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame.

Thermal energy is being transferred by conduction.

Radiation transfers thermal energy by electromagnetic waves.

Radiation does not transfer thermal energy by direct contact.

Thermal energy is the heat energy that is produced with an increase in temperature. No, thermal energy is not transferred by radiation when eggs are cooked.

Radiation is the process of thermal energy transfer that emits heat in all directions and does not require an intervening medium to travel.

Thermal energy is not transferred by radiation in the image as the eggs are in contact with the pan and the pan is in direct contact with a flame that radiates the heat by conduction.

Therefore, heat transfers by conduction and not by radiation.

Answer:

They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes?  Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.

Explanation:

Due to the effects of the environment, genetically identical twins might have different phenotype.

The qualities or visible characteristics of an organism are its phenotype. It depends on how the environment and the genotype, or genetic code, of the organism interact.

Although human monozygotic twins as well as other genetically identical species may share startling physical similarities, they frequently differ in key characteristics, such as complicated diseases. The effects of the environment have generally been blamed for this variance across organisms with essentially identical chromosomal DNA sequences.

Therefore, due to the effects of the environment, genetically identical twins might have different phenotype.

Answer:

In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Answer:

77460 g

Explanation:

To solve this problem first we convert molecules into moles, using Avogadro's number:

3.47x10²⁶ molecules ÷ 6.023x10²³ molecules/mol = 576.12 moles

Then we convert 576.12 CuCl₂ moles into grams, using its molar mass:

576.12 mol * 134.45 g/mol = 77460 g

So the answer is 77460 g, or 77.46 kg.

Answer:

15 moles  of CO₂

Explanation:

Given data:

Number of formula units = 8.9 ×10²⁴ formula units

Number of moles of CO₂ = ?

Solution:

The given problem will solve by using Avogadro number.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ formula units

8.9 ×10²⁴ formula units  × 1mol / 6.022 × 10²³ formula units

1.5 mol ×10¹ mol

Given

Skeleton equation(unbalanced equation) :

NaCl+F2⇒NaF+Cl2

Required

The number of atoms

Solution

We balance the reactions to find the reaction coefficient, which is then used to calculate the number of atoms in the reactants and products

Balanced equation

2NaCl + F2 → 2NaF + Cl2

A balanced reaction will show that the number of atoms in the reactants and products is the same

Na = 2 atoms

Cl = 2atoms

F = 2 atoms

Na = 2 atoms

F = 2 atoms

Cl = 2 atoms

[tex]7.13\times 10^{-2}\ ft^2[/tex]

Explanation:

The area of a telescope lens is 6.668 × 10³ mm²

We need to convert the area in ft².

We know that,

[tex]1\ mm^2=1.07\times 10^{-5}\ ft^2[/tex]

It means,

[tex]6.668 \times 10^3\ mm^2=6.668 \times 10^3\times 1.07\times 10^{-5}\ ft^2\\\\=0.0713\ ft^2[/tex]

or

[tex]0.0713\ ft^2=7.13\times 10^{-2}\ ft^2[/tex]

So, the required answer is [tex]7.13\times 10^{-2}\ ft^2[/tex].

The number of moles of NaCl = 0.103

Given

6 gram sample of NaCl

Required

moles

Solution

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

mole = mass : molar mass

Molar mass of NaCl = 58.5 g/mol

Input the value :

mole = 6 g : 58.5 g/mol

mole = 0.103

The answer to this question would be true.

The question is incomplete, the complete question is;

The student collects the H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas-collection tube, as shown in the diagram below. The volume is measured to be 45.6mL . The atmospheric pressure in the lab is measured as 765 torr , and the equilibrium vapor pressure of water at 298 K is 24 torr .(i) The pressure inside the tube due to the H2(g)

Answer:

741 torr

Explanation:

From the question we can see that the atmospheric pressure in the lab is 765 torr.

The vapour pressure of water = 24 torr

From Dalton's law of partial pressure, we know that;

Total pressure = Pressure of the H2 + Partial pressure of water vapour

Therefore;

Pressure of H2 = Total pressure - Partial pressure of water vapour

Pressure of H2 = 765 torr - 24 torr = 741 torr

Answer:

3.15N

Explanation:

We use this equation:

F= k∆x

Where ∆x refers to the amount or stretch or compression and k is the spring constant.

F = force

k = spring constant

∆x = change in length of spring

To find the value of F:

F= k∆x

F= 12.6x0.25

F= 3.15N
