Answer:

what are you saying ma guy?

Explanation:

Answer:

A) Oscillate

B) Liquid

C) Loosely

That is, "They can oscillate about a fixed point. Particles in a liquid are still close together but are arranged loosely (not in a pattern)

Explanation:

The above speaks to the various states that matter can be in. They are Gaseous, Liquid, and Solid.

The state described above is the liquid state. Recall that all matter are made up of microscopic particles. These particles when viewed under a microscope are observed to be in a state of continuous motion.

The degree of motion and arrangement is determined by the temprature of the substance. The higher the temperature, the faster and more lose the particles become.

Water for instance would in a liquid state, have its particles oscillate freely about each other giving it the ability to take the shape of the container in which it is put. Its particles are not rigidly fixed together at this point and can slide past each other easily.

In a solid-state (that is ice) the particles become tightly packed and there is less oscillation. Whilst in a gaseous state (vapor, that is) the particles o or molecules are very far apart.

The maximum amount of carbon dioxide that can be formed from 15.2 g of glucose is approximately 22.31 grams.

To determine the maximum amount of carbon dioxide (CO2) that can be formed from 15.2 g of glucose (C6H12O6), we need to use the stoichiometry of the balanced chemical equation for the combustion of glucose.

The balanced chemical equation for the combustion of glucose is:
C6H12O6 + 6O2 -> 6CO2 + 6H2O

From the equation, we can see that 1 mole of glucose reacts with 6 moles of oxygen to produce 6 moles of carbon dioxide.

First, we need to calculate the number of moles of glucose in 15.2 g:
Molar mass of glucose (C6H12O6) = (12.01 g/mol x 6) + (1.01 g/mol x 12) + (16.00 g/mol x 6) = 180.18 g/mol
Moles of glucose = Mass of glucose / Molar mass of glucose = 15.2 g / 180.18 g/mol ≈ 0.0845 mol

Since 1 mole of glucose reacts with 6 moles of oxygen, we need to multiply the number of moles of glucose by 6 to determine the moles of oxygen:
Moles of oxygen = 0.0845 mol x 6 = 0.507 mol

Finally, since 1 mole of glucose produces 6 moles of carbon dioxide, we can calculate the maximum amount of carbon dioxide formed:
Moles of carbon dioxide = Moles of glucose x 6 = 0.0845 mol x 6 = 0.507 mol

To convert the moles of carbon dioxide to grams, we can multiply by the molar mass of carbon dioxide:
Molar mass of carbon dioxide (CO2) = (12.01 g/mol x 1) + (16.00 g/mol x 2) = 44.01 g/mol
Mass of carbon dioxide = Moles of carbon dioxide x Molar mass of carbon dioxide = 0.507 mol x 44.01 g/mol ≈ 22.31 g

Therefore, the maximum amount of carbon dioxide that can be formed from 15.2 g of glucose is approximately 22.31 grams.

The given statement “Shorter product life cycles have led to increased demand uncertainty and difficulty in forecasting” is true because shorter product life cycles have led to increased demand uncertainty and difficulty in forecasting. It is becoming more difficult to predict demand, and there is a higher probability of product failure than there was in the past.

There are several factors responsible for this increased demand uncertainty and difficulty in forecasting. One of the most significant factors is the decrease in product life cycle length. Shorter product life cycles imply that new items and designs are being introduced on a more frequent basis.Product life cycles are the stages that a product passes through from conception to eventual obsolescence. It starts with the development of the product and continues until the product is no longer in use. It includes the introduction stage, growth stage, maturity stage, and decline stage.A product's life cycle has an impact on supply chain management since it has a significant impact on demand forecasting. As a result, any adjustments in demand forecasts must be accompanied by adjustments in supply chains. In a nutshell, shorter product life cycles have resulted in increased demand uncertainty and difficulty in forecasting, making it more challenging to manage supply chains effectively.

So, shorter product life cycles have led to increased demand uncertainty and difficulty in forecasting is true.

Answer:

0.017 moles of ammonia remains after the reaction is stopped.

Explanation:

The reaction is:

4NH₃  +  5O₂  →  4NO  +  6H₂O

The first step is to convert the mass to moles, of each reactant:

2 g .  1mol/ 17g = 0.117 moles of NH₃

4 g . 1mol /32g = 0.125 moles of O₂

Ammonia, states the question, is the excess reactant so we can confirm it,

5 moles of oxygen need 4 moles of ammonia to react (by stoichiometry)

Then, 0.125 moles of oxygen may react to (0.125 . 4) / 5 = 0.1 moles

As we have 0.117 moles of ammonia and we need 0.1 moles.

(0.117 - 0.1) = 0.017 moles remains after the reaction is completed.

If we convert the moles to mass we have:

0.017 mol . 17 g /1mol = 0.289 g

At 27°C and constant pressure, the volume of the gas in the balloon is approximately 240.0 mL.To solve this problem, we need to use the combined gas law, which relates the pressure, volume, and temperature of a gas:\((P_1V_1)/T_1 = (P_2V_2)/T_2\)

Where \(P_1\)and \(T_1\) are the initial pressure and temperature, \(V_1\)is the initial volume, \(P_2\) and \(T_2\) are the final pressure and temperature, and  \(V_2\) is the final volume we are trying to find.We are given the initial volume \(V_1\) = 120.0 mL, the initial temperature \(T_1\)= -123C, and the pressure is constant, so we can assume \(P_1 = P_2\). We need to convert the temperatures to Kelvin, so \(T_1\) = 150 K and \(T_2\)= 300 K.

Using the combined gas law, we can solve for \(V_2\):
\((P_1V_1)/T_1 = (P_2V_2)/T_2\)
\((P_1)(120.0 mL)/(150 K) = (P_2)(V_2)/(300 K)\)
Simplifying, we can cancel out the pressures and cross-multiply:
\(V_2\) = (120.0 mL)(300 K)/(150 K)
\(V_2\) = 240.0 mL
Therefore, the volume of the gas in the balloon at 27C is 240.0 mL.To answer your question, we'll use Charles's Law, which states that the volume of a gas is directly proportional to its temperature in Kelvin, as long as the pressure remains constant.Charles's Law formula: \(V_1/T_1 = V_2/T_2\)

Where:
\(V_1\) = initial volume = 120.0 mL
\(T_1\) = initial temperature = -123°C
\(V_2\)= final volume (what we want to find)
\(T_2\) = final temperature = 27°C

First, we need to convert the temperatures from Celsius to Kelvin:
\(T_1\)(K) = -123°C + 273.15 = 150.15 K
\(T_2\)(K) = 27°C + 273.15 = 300.15 K

Now, we can plug in the values into Charles's Law formula:
(120.0 mL / 150.15 K) = (\(V_2\) / 300.15 K)
To find \(V_2\), we'll rearrange the equation and multiply both sides by 300.15 K:
\(V_2\) = (120.0 mL / 150.15 K) × 300.15 K
\(V_2\)≈ 240.0 mL

The trials are precise but are not accurate.

The degree to which a measured value approaches a standard or true value is referred to as accuracy. Accuracy is achieved by taking small readings. On the other hand, precision is defined as how closely two or more measurements match one another.

Therefore, accuracy is the degree to which a measurement is near its real value, whereas precision is the degree to which subsequent measurements taken in the same circumstances get the same results.

Now, the three readings obtained by weighing an apple using a balance are trial 1, trial 2, and trial 3.

The mass of the apple during the first trial =167.0g.

The mass of the apple during the second trial =166.9g.

The mass of the apple during the third trial = 167.2g

The true mass of the apple =172g

Therefore, a true mass describes your results in terms of precision and accuracy.

Now, in your three trials to measure the weight of the mass of the apple, your readings replicates were extremely near to each other. As a result, your trials are precise. However, the true mass was 172 g, and if you average your three trials, you would get roughly 167.1 g, which isn't very near to the true mass. As a result, your trials are precise but not accurate.

The percent yield of \(Fe_2S_3\), according to the given parameters, would be  32.91%.

The percent yield of a particular product from a reaction is the actual amount of that product formed relative to the stoichiometric or theoretical amount that is supposed to be formed.

The percent yield of a reaction can be mathematically expressed as:

Percent yield = actual yield/theoretical yield x 100%

In this case:

Actual yield = 284 g

Theoretical yield = 863 g

Percent yield = 284/863 x 100

Explanation:

The pressure in a 22.0 L cylinder filled with 41.1 g of oxygen gas at a temperature of 331 K is 1.58 atm.

We have,

The volume of the cylinder (V) = 22.0 L

Oxygen gas (O2) = 41.1 g

Temperature (T) = 331 K

We need to find the pressure (P) of oxygen gas in the cylinder.

P = (nRT) / V

Where,

R = 0.0821 L atm K−1mol−1

n = 41.1 g / 32 g/mol (O2 has a molar mass of 32 g/mol)

n = 1.284 mol

P = (1.284 mol × 0.0821 L atm K−1mol−1 × 331 K) / 22.0 L= 123.8 atm

Therefore, the pressure is 1.58 atm.
