Norman sliding his foot across the floor would create heat energy through friction (C)

When a person is sliding on the floor, the foot would rub against the floor. The process would result in friction between the feet and the floor.

In addition to that, the potential energy (resting energy) is getting converted to kinetic energy (energy resulting from motion). The difference between the energy of an object at resting state and motion would result in production of heat energy. This is caused mainly due to friction.

Thus, when Norman’s foot is sliding across the floor, it would create heat energy through friction.

The metabolic process that occurred in the apparatus of the experiment given in the question is photosynthesis. The graphed results of the experiment are related to the process of photosynthesis.

Photosynthesis is the process in which the green plants use the energy of sunlight to convert carbon dioxide and water into glucose and oxygen. In this process, chlorophyll pigment, present in the chloroplasts of the plant cells, captures the energy of sunlight. This captured light energy is used to convert water and carbon dioxide into oxygen and glucose.

In the experiment mentioned above, the metabolic process that occurred in the apparatus is photosynthesis. It is because spinach leaves were used in the experiment to observe the amount of oxygen (O2) and carbon dioxide (CO2) present in the leaves.

The graphed results of this experiment show that the amount of oxygen in the leaves increased over time while the amount of carbon dioxide decreased. This is because the leaves absorbed carbon dioxide from the air and converted it into glucose and oxygen through the process of photosynthesis. As a result, the amount of oxygen increased over time, and the amount of carbon dioxide decreased. Hence, it can be concluded that the graphed results of the experiment are related to the process of photosynthesis.

Setting negative values to zero prevents errors in calculations.

The purpose of calibrating the calorimeter in a calorimetry investigation is to determine the heat capacity of the calorimeter. This means that you must determine how much energy is required to raise the temperature of the calorimeter by one degree Celsius. This is critical because the heat capacity of the calorimeter will be used to determine the amount of heat transferred in the system during the experiment.

If we did not calibrate the calorimeter, we would introduce a systematic error in the results obtained. This is because we would not know the heat capacity of the calorimeter and could not calculate the amount of heat transferred accurately.

A negative value for the heat capacity should be set to zero. This is because it is not possible to have a negative heat capacity. If a negative value was obtained, it would indicate an error in the experiment or calculations, and it would be necessary to repeat the experiment to determine the correct value.

Based on the equation of the reaction and the data provided,

A limiting reactant is a reactant which is used up in a reaction after which the reaction stops.

In the given reaction:

3 NH4NO3 + Na3PO4 → (NH4)3PO4 + 3 NaNO3

The limiting reactant is determined from the stoichiometry of the eqaution.

Moles of reactant = mass/molar mass

Molar mass of NH4NO3 = 80 g/mol

Molar mass of Na3PO4 = 165 g/mol

Molar mass of (NH4)3PO4 = 150 g/mol

Molar mass of NaNO3 = 85 g/mol

From the equation of the reaction, 240 g (3 × 80) of NH4NO3 is required to react with 165 g of Na3PO4

There are only 30.0 g of NH4NO3 reacting with 50.0 g of Na3PO4

30 g of Na3PO4 will react with 30 × 165/240 = 20.625 g of Na3PO4

Therefore, NH4NO3 is the limiting reactant

Na3PO4 is the excess reactant

mass of Na3PO4 left = 50 - 20.625

mass of excess reactant left = 29.375 g

moles of NH4NO3 in 30 g = 30/80 = 0.375 moles

3 moles of NH4NO3 produces 1 mole of (NH4)3PO4

0.375 moles of NH4NO3 will produce 0.375 × 1/3 = 0.125 moles of (NH4)3PO4

mass of 0.125 moles of (NH4)3PO4 = 0.125 × 150

mass of (NH4)3PO4 produced = 18.75 g of (NH4)3PO4

3 moles of NH4NO3 produces 3 moles of NaNO3

0.375 moles of NH4NO3 will produce 0.375 moles of NaNO3

mass of 0.375 moles of NaNO3 = 0.375 × 85

mass of NaNO3 produced = 31.875 g of NaNO3

Percent yield = 78.7% , the correct answer is D) 78.7%, which represents the percent yield of NaCl in the reaction.

To calculate the percent yield of NaCl in the given chemical equation, we need to compare the actual yield of NaCl with the theoretical yield. The theoretical yield is the amount of NaCl that would be produced if the reaction went to completion based on stoichiometry.

First, we need to determine the theoretical yield of NaCl. By examining the balanced equation, we can see that the stoichiometric ratio between CuCl2 and NaCl is 1:2. This means that for every 1 mole of CuCl2, 2 moles of NaCl are produced.

Step 1: Convert the mass of CuCl2 to moles using its molar mass.

Molar mass of CuCl2 = 63.55 g/mol (atomic mass of Cu) + 2 × 35.45 g/mol (atomic mass of Cl)

Molar mass of CuCl2 = 134.45 g/mol

Moles of CuCl2 = 31.0 g / 134.45 g/mol ≈ 0.231 mol

Step 2: Use the stoichiometry to calculate the theoretical yield of NaCl.

Since the stoichiometric ratio between CuCl2 and NaCl is 1:2, the moles of NaCl produced will be twice the moles of CuCl2.

Moles of NaCl (theoretical) = 2 × 0.231 mol = 0.462 mol

Step 3: Convert the moles of NaCl to grams using its molar mass.

Molar mass of NaCl = 22.99 g/mol (atomic mass of Na) + 35.45 g/mol (atomic mass of Cl)

Molar mass of NaCl = 58.44 g/mol

Theoretical yield of NaCl = 0.462 mol × 58.44 g/mol ≈ 26.96 g

Now, we can calculate the percent yield using the formula:

Percent yield = (Actual yield / Theoretical yield) × 100

Percent yield = (21.2 g / 26.96 g) × 100 ≈ 78.7%

Option D

The mass of the product in the crucible after heating in Experiment 2 is 20 grams.

In order to determine the number of grams of product in the crucible after heating in Experiment 2, we need to follow these steps:
1. Start by measuring the mass of the empty crucible using a balance. Let's say the mass of the crucible is 50 grams.
2. Perform the decomposition reaction and heat the sample in the crucible.
3. After heating, allow the crucible to cool down to room temperature.
4. Once cooled, measure the mass of the crucible with the product inside using the same balance. Let's say the mass of the crucible with the product is 70 grams.
5. To calculate the mass of the product, subtract the mass of the empty crucible from the mass of the crucible with the product:
Mass of product = Mass of crucible with product - Mass of empty crucible
Mass of product = 70 grams - 50 grams = 20 grams
Therefore, the mass of the product is 20 grams.

The problem that arises when NaCl and a drying agent are not added sequentially to the ether layer is that the organic layer may contain moisture or water droplets that can interfere with the subsequent procedure.

Therefore, NaCl is added to the ether layer first, followed by a drying agent, to ensure that the organic layer is dry and free of water droplets that can interfere with the reaction. A drying agent is used to dry the organic layer of a solvent, which is necessary to avoid water droplets that can interfere with the reaction.

Sodium sulfate is the most commonly used drying agent, which can remove traces of water from organic compounds. To remove water from the organic layer, anhydrous magnesium sulfate is also used. The dehydration process usually removes excess water from the organic layer.

The empirical formula of the compound made up of 70.0% iron and 30.1% oxygen is Fe₂O₃, and the molecular formula can be the same as the empirical formula, Fe₂O₃.

To determine the empirical formula, we need to find the simplest whole-number ratio of the elements present in the compound. Given the percentages of iron (Fe) and oxygen (O), we can assume a 100 g sample of the compound.

The mass of iron is 70.0 g (70.0% of 100 g), and the mass of oxygen is 30.1 g (30.1% of 100 g).

Next, we calculate the moles of each element using their respective molar masses:

moles of Fe = 70.0 g / 55.85 g/mol ≈ 1.252

moles of O = 30.1 g / 16.00 g/mol ≈ 1.881

Then, we divide the number of moles of each element by the smallest number of moles to obtain the simplest whole-number ratio:

1.252 / 1.252 ≈ 1 (for Fe)

1.881 / 1.252 ≈ 1.5 (for O)

Since we need to express the empirical formula using whole numbers, we multiply the ratio by 2 to obtain the simplest ratio:

1 × 2 = 2 (for Fe)

1.5 × 2 = 3 (for O)

Therefore, the empirical formula of the compound is Fe₂O₃, and the molecular formula can be the same as the empirical formula, Fe₂O₃.

Answer:

The work done by the gas expansion is 5875 J,

Since the work done is positive, the work is done by the gas on the surroundings.

Explanation:

Given;

change in internal energy, ΔU = -4750 J

heat transferred to the system, Q = 1125 J

The change in internal energy is given by;

ΔU = Q - W

Where;

W is the work done by the system

The work done by the system is calculated as;

W = Q - ΔU

W =  1125 - (-4750)

W = 1125 + 4750

W = 5875 J

Since the work done is positive, the work is done by the gas on the surroundings (energy flows from the gas to the surroundings).

Therefore, the work done by the gas expansion is 5875 J
