PLEASE ANSWER ASAP

A) Calculate the molecular formula of a compound with an empirical formula of P2O5 and a molar mass of 283.88 g/mol.


B) Calculate the empirical formula of a compound containing 52.14% carbon, 13.12% hydrogen, and 34.73% oxygen.

Answers

Answer:

P4O10

Explanation:

Imagine that you work in a crime lab, and the police bring to you a sample of a white powder that they believe to be cocaine (C17H21NO4). When you carry out a combustion analysis on a 32 mg sample, you find that the sample contained 21.9 mg of carbon, 2.5 mg of hydrogen, 2.3 mg of nitrogen, and 5.3 mg of oxygen. What is the empirical formula for the white powder? Is this consistent with the molecular formula for cocaine?

Answers

The empirical formula of the white powder is CH1.5N1O2.

Empirical formula calculation

To find the empirical formula of the white powder, we need to determine the ratios of the elements present in the sample. We can assume that the sample contains 100 g of the powder, and then convert the masses of each element to moles using their molar masses:

mass of C = 21.9 mg = 0.0219 g = 0.0018 mol

mass of H = 2.5 mg = 0.0025 g = 0.0025 mol

mass of N = 2.3 mg = 0.0023 g = 0.0017 mol

mass of O = 5.3 mg = 0.0053 g = 0.0033 mol

Next, we can divide each of the mole values by the smallest mole value to get the simplest whole number ratio of the elements:

C: 0.0018 mol / 0.0017 mol = 1.06 ≈ 1

H: 0.0025 mol / 0.0017 mol = 1.47 ≈ 1.5

N: 0.0017 mol / 0.0017 mol = 1

O: 0.0033 mol / 0.0017 mol = 1.94 ≈ 2

Therefore, the empirical formula of the white powder is CH1.5N1O2.

To check if this is consistent with the molecular formula for cocaine (C17H21NO4), we can calculate the molecular formula mass of the empirical formula and compare it to the molecular formula mass of cocaine:

Empirical formula mass = 13.5 g/mol (approximately)

Molecular formula mass of cocaine = 303.4 g/mol

The empirical formula mass is much smaller than the molecular formula mass of cocaine, so the empirical formula is not consistent with the molecular formula.

Therefore, this suggests that cocaine is a larger molecule, made up of many repeating units of CH1.5N1O2. To determine the molecular formula of cocaine, we would need additional information, such as the molecular mass of the compound.

If you constructed graphs what trends do they indicate in your data


Were there any problems with the experiment or the methods? Did you have any surprising results?


What do the results tell you about your hypothesis?



How does the data support your claim above?


If you could repeat the experiment and make it better what would you do differently and why?

Answers

Answer:

The purpose of the lab is to study thermal energy transfer and its effects on different materials. The topic is important because understanding thermal energy transfer is essential to many fields, including engineering, physics, and chemistry. The question you are trying to answer may be something like "How does thermal energy transfer affect the temperature of different materials?"

Your hypothesis may be something like "Materials with high thermal conductivity will transfer heat more efficiently than materials with low thermal conductivity."

To test this hypothesis, you may use a setup where you have a heat source, a temperature sensor, and various materials with different thermal conductivities. You would measure the temperature changes of the materials as they are heated and cooled.

The key results of your lab may include the temperature changes of each material over time, the rate of heat transfer, and any observations about the behavior of the materials during the experiment. To summarize the data, you may create graphs or charts that show the temperature changes of the materials over time.

You may have quantitative data such as temperature readings and calculations of heat transfer rates, as well as qualitative data such as observations of the behavior of the materials during the experiment. You can organize this data in tables, graphs, and written descriptions.

The results may indicate that materials with higher thermal conductivity do transfer heat more efficiently, as your hypothesis predicted.

If you constructed graphs, you may observe trends such as a steeper slope for materials with higher thermal conductivity or a plateau in temperature once a material reaches its maximum heat capacity.

Possible problems with the experiment may include equipment malfunctions or inaccuracies in temperature readings. Surprising results may include unexpected temperature changes or behavior of certain materials.

The results may support your hypothesis and indicate that materials with high thermal conductivity transfer heat more efficiently.

The data supports your claim by showing clear temperature changes and rates of heat transfer for each material.

If you could repeat the experiment, you may try using different materials or adjusting the setup to control for potential confounding factors. For example, you may try using materials with similar heat capacities or reducing heat loss during the experiment.

what is the ionization constant for a 0.10 mole/dm3 of ethanoic acid solution which has a ph of 2.88​

Answers

The ionization constant (Ka) for a 0.10 M solution of ethanoic acid with a pH of 2.88 is [tex]5.82 * 10^(^-^5^)[/tex]

What does equilibrium constant mean?

The ratio of reactant to product amounts that is used to predict chemical behaviour is the definition of the equilibrium constant for a chemical process.

Ka = [H+][A-] / [HA]

where [H+] is the concentration of hydrogen ions, [A-] is the concentration of the conjugate base, and [HA] is the concentration of the weak acid.

For ethanoic acid (also known as acetic acid), the ionization reaction is:

CH3COOH + H2O ⇌ CH3COO- + H3O+

pH = -log[H3O+]

The Ka expression can now be written as:

[tex]Ka = (x)^2 / (0.10 - x)[/tex]

At equilibrium, the value of x is very small compared to 0.10 M, so we can make the approximation that 0.10 - x ≈ 0.10.

Therefore, we can simplify the Ka expression to:

[tex]Ka = x^2 / 0.10[/tex]

To solve for x, we can use the equilibrium concentration of [H3O+] we calculated earlier:

[tex]x = [H3O+] = 7.68 * 10^(^-^3^) M[/tex]

Substituting this value into the simplified Ka expression, we get:

[tex]Ka = (7.68 * 10^(^-^3^))^2 / 0.10 = 5.82 * 10^(^-^5^)[/tex]

Barometric pressure 738 mmHg

Vapor pressure of water at 23.0 °
21.0 mmHg

Calculate the moles of hydrogen gas produced by the reaction.

Answers

To calculate the moles of hydrogen gas produced by the reaction, we need to use the ideal gas law equation:

PV = nRT

Where:

P = Total pressure (barometric pressure - vapor pressure of water)

V = Volume of hydrogen gas collected

n = Number of moles of hydrogen gas

R = Universal gas constant (0.08206 L·atm/mol·K)

T = Temperature in Kelvin (23°C + 273.15)

What is the  moles of hydrogen gas produced by the reaction?

First, let's calculate the total pressure:

Total pressure = Barometric pressure - Vapor pressure of water

Total pressure = 738 mmHg - 21.0 mmHg

Total pressure = 717.0 mmHg

Now, we can plug in the values into the ideal gas law equation:

n = PV/RT

n = (717.0 mmHg)(94.27 mL)/(0.08206 L·atm/mol·K)(23.0°C + 273.15)

n = 0.00345 mol

Therefore, the moles of hydrogen gas produced by the reaction is 0.00345 mol.

- Most of the place inside an atom is empty because particles passed straight through.

- some particles deflected in small angles meaning the positive charge in an atom occupies very less space.

The density of the solid cylinder is calculated to be as  approximately 17.7 g/cm³.

What is meant by density?

The mass per unit of volume of a substance is known as density and symbol that is mostly used for density is ρ.

As the formula for the density of an object is:

density = mass / volume

volume = π x radius² x height

volume = π x (3cm)² x 10cm

volume = 282.74 cm³

mass = 5kg x 1000g/kg = 5000g

density = mass / volume

density = 5000g / 282.74 cm³

density ≈ 17.7 g/cm³

A mind map is a visual diagram that many people use to organize their thoughts and to summarize information on a specific topic.The topic (Eastern Approaches to a Unified Reality) goes in the centre of the page, and the main topics (Hinduism, Buddhism, Confucianism and Taoism) extend out from the centre and branch out into related general concepts (for example, the nature of ultimate reality, the relationship between mind and matter, what is self, texts, processes, key figures, the meaning of life, etc). Use the Internet, your own libraries and any other resources at your disposal to find out more information about Hinduism, Confucianism, Buddhism, and Taoism.Also, you should use symbols, pictures and colour to enhance your mind map. which of the following is true about anecdotes?
