glycerol and fatty acids are the building blocks for?

Answer:

We can use the combined gas law to solve this problem:

(P1V1)/T1 = (P2V2)/T2

where P1, V1, and T1 are the initial pressure, volume, and temperature, respectively, and P2 and T2 are the final pressure and temperature, respectively. We can solve for V2, the final volume:

V2 = (P1V1T2)/(P2T1)

Plugging in the values we have:

V2 = (4.45 atm * 1.00 L * 242 K) / (0.289 atm * 296 K)

V2 = 132.5 L

Therefore, the new volume of the balloon is approximately 132.5 liters.

The total charge that flows while the battery is being charged is approximately 193,939.39 Coulombs.

To calculate the total charge that flows while the battery is being charged, we can use the relationship between electrical energy, potential difference, and charge.

The electrical energy (E) stored in the battery is given as 64 mega Jules (64 MJ). The potential difference (V) provided by the battery is 330 volts. We know that the energy (E) is equal to the product of the potential difference (V) and the charge (Q):

E = V * Q

Since the charging process is 100% efficient, all the electrical energy supplied is stored in the battery. Therefore, we can rearrange the equation to solve for the charge (Q):

Q = E / V

Substituting the given values, we have:

Q = 64 MJ / 330 V

To perform the calculation, we need to convert mega Jules (MJ) to joules (J) since the SI unit of energy is joules. One mega Joule is equal to 1 million joules:

Q = (64 * 10^6 J) / 330 V

Calculating the division:

Q ≈ 193,939.39 Coulombs

Therefore, the total charge that flows while the battery is being charged is approximately 193,939.39 Coulombs.

This value represents the quantity of electric charge transferred during the charging process, and it indicates the amount of electricity that enters the battery.

Answer:

Stomata take in water, sunlight, and carbon dioxide and release oxygen.

Explanation:

Photosynthesis collects and absorbs sunlight and converts the sunlight into sugars (glycose), then the plant stores the sugar and uses it.

In General Chemistry, it is possible to use the Q-test with a 90% confidence level or the standard deviation with a 90% confidence level to decide whether a data point should be ignored when computing the average.

According to Appendix D of the lab manual for General Chemistry, a data point can be considered an outlier and can be ignored when calculating the average if it falls outside the critical range determined by the Q-test at 90% confidence level.

The Q-test is a statistical test that compares the difference between a suspected outlier and the nearest value to it. If the calculated Q-value is greater than the critical Q-value for the given number of data points at 90% confidence level, then the suspected data point is considered an outlier and can be removed from the data set.

Alternatively, the standard deviation can also be used to determine if a data point is an outlier. A data point can be considered an outlier if it falls outside of the range of ± 1.645 standard deviations from the mean at 90% confidence level, or ± 1.96 standard deviations from the mean at 95% confidence level.

In summary, the Q-test at 90% confidence level or the standard deviation at 90% confidence level can be used to determine if a data point should be ignored when calculating the average in General Chemistry.

Gas mixes can be regarded as ideal gas mixtures for the purpose of calculation at low pressure or high temperature.

The ability of the gas particles to interact with one another depends on the system's temperature and pressure, and these interactions severely limit the precision of the Ideal Gas Law.Because the volume occupied by the gas is relatively small and the intermolecular distance between the molecules shrinks at low temperature and high pressure, the ideal gas law fails in these conditions. Real gases have lower pressure than the ideal gas equation because attraction forces between molecules do occur in real gases. The van der Waals equation takes this condition into account. As it is assumed that perfect gas molecules have no volume, the volume that they can move in is always the same as the volume of the container. In contrast, the volumes of the molecules in a genuine gas are minuscule but measurable.

The equation that represents the minimum chlorine concentration is

\(Cl_{2}\) =  2 ppm.

Chlorine is often added to a swimming pool to sanitize water and make it safe for swimming. It is very important to keep track of the chlorine concentration that we add to the swimming pool.  

If the concentration of chlorine goes beyond 4 ppm then it might cause harm to the people using that swimming pool, but the concentration should also be greater than 2 ppm so that proper sanitation is ensured. Hence the chlorine concentration should be in the range of 2 to 4 ppm.

https://brainly.com/question/19460448

The equation representing the acceptable chlorine concentration in a swimming pool is given by the inequality 2 ppm ≤ Cl ≤ 4 ppm, where 'Cl' is the chlorine concentration. The chlorine concentration should ideally be between 2 and 4 parts per million (ppm).

The equation that represents the maximum and minimum chlorine concentration in a swimming pool can be expressed as a simple inequality, based on parts per million (ppm) values. This equation is:

2 ppm ≤ Cl ≤ 4 ppm

In this equation, 'Cl' represents the chlorine concentration in the swimming pool. If the chlorine concentration is less than 2 ppm, it may not be sufficient to properly sanitize the water. On the other hand, if it's more than 4 ppm, it may cause discomfort or health problems to swimmers. So the target range for chlorine concentration is between 2 and 4 ppm.

Answer: conjugate base of a weak acid

Explanation: If the anion is a conjugate base of a weak acid, the solution would be basic. This is because weak acids do not produce enough hydrogen ions in the solution so does not really affect the acidity, so the conjugate base can react with water in the solution to produce a basic solution.

A confirmatory test allows us to find the presence of carbon dioxide, an example of one is the use of limewater, which reacts with it and produces a white precipitate.

A  confirmatory test for carbon dioxide (CO2) involves the use of limewater (calcium hydroxide solution). The test relies on the reaction between CO2 and limewater, which produces a white precipitate of calcium carbonate.

Here's how the test is conducted:

Prepare a clear limewater solution by dissolving calcium hydroxide (Ca(OH)2) in water. The solution should be colorless and transparent.

Expose the gas or substance suspected to contain CO2 to the limewater. This can be done by either bubbling the gas through the limewater or passing the gas over the surface of the limewater.

Observe any changes in the limewater. If carbon dioxide is present, it will react with the calcium hydroxide in the limewater to form insoluble calcium carbonate (CaCO3). The formation of calcium carbonate results in a milky or cloudy appearance in the limewater due to the formation of a white precipitate.

The reaction between CO2 and limewater can be represented as follows:

CO2 (g) + Ca(OH)2 (aq) → CaCO3 (s) + H2O (l)

The appearance of the white precipitate indicates the presence of carbon dioxide. This test is commonly used to confirm the presence of CO2 gas in various contexts, such as in exhaled breath, chemical reactions involving CO2, or in identifying CO2 emissions from a source.

For balancing the chemical equation C7H16 + O2 → CO2 + H2O, we can use linear algebraic techniques. We need to determine the coefficients that balance the number of atoms on both sides of the equation.

Let's denote the coefficients for C7H16, O2, CO2, and H2O as a, b, c, and d, respectively.

The balanced chemical equation can be written as:

aC7H16 + bO2 → cCO2 + dH2O

To balance the carbon (C) atoms, we have:

7a = c (Equation 1)

To balance the hydrogen (H) atoms, we have:

16a = 2d (Equation 2)

To balance the oxygen (O) atoms, we have:

2b = 2c + d (Equation 3)

We have three equations (Equations 1, 2, and 3) and four unknowns (a, b, c, d). To solve this system of equations, we can write it in matrix form and find the solution using linear algebraic techniques.

The augmented matrix for the system of equations is:

[ 7 0 -1 0 | 0 ]

The mass of carbon dioxide released during the reaction is 2.6 grams.

To determine the mass of carbon dioxide released during the reaction between sodium hydrogen carbonate (NaHCO3) and acetic acid (CH3COOH), we need to calculate the difference in mass before and after the reaction.

Before the reaction:

Mass of NaHCO3 = 3.8 g

Mass of acetic acid = 10.5 g

Total mass before the reaction = Mass of NaHCO3 + Mass of acetic acid = 3.8 g + 10.5 g = 14.3 g

After the reaction:

Mass of the contents of the reaction vessel = 11.7 g

To find the mass of carbon dioxide released, we calculate the difference in mass:

Mass of carbon dioxide released = Total mass before the reaction - Mass of the contents of the reaction vessel

= 14.3 g - 11.7 g

= 2.6 g

Therefore, the mass of carbon dioxide released during the reaction is 2.6 grams.

The compositions of the intermetallic compounds A3B and AB3 are given as percentages of element A and element B, respectively.

Another approach to identifying element B would be to perform chemical analysis on small samples of the compounds. This would involve determining the elemental composition of the samples using techniques such as X-ray fluorescence (XRF) or inductively coupled plasma mass spectrometry (ICP-MS). From the elemental composition, element B could be identified based on its position in the periodic table and its known properties. However, the compositions do not provide enough information to determine the identity of element B.

In order to identify element B, additional information is needed. One possible way to identify element B is to compare the known properties of the compounds formed by A and B. For example, if A forms a cubic structure and B forms a tetragonal structure, then element B is likely zirconium (Zr). However, without additional information, it is not possible to definitively identify element B using only the given compositions of A3B and AB3.
