Answers

Answer: 1L of Ne gas

The answer is Option C , 1L of Ne gas will have the same number of molecules at 1 L of C₂H₄ gas

What is STP ?

At standard temperature and pressure, a system is said to have a temperature of zero degrees centigrade (273 Kelvins) and the pressure equal to the atmosphere is always 1 atm.

Additionally, one mole of any gas at STP occupies a volume of 22.414 L.

This concept only holds true for gases.

So for a gas having same pressure , temperature and moles according to the Ideal Gas Law , volume also needs to be same

                                       

                                           pV=nRT

and in the given option ,Option C has the same volume as that of 1 L of C₂H₄ gas .

Titaium oxside is often added to food to color it white. If a jelly bean contains approximately 1.28x10-5 moles of TiO2, how many grams of TiO2 are in a jelly bean

Answers

Answer:

1.02 × 10⁻³ g

Explanation:

Step 1: Given data

Number of moles of titanium (IV) oxide in 1 jelly bean (n): 1.28 × 10⁻⁵ moles

Step 2: Calculate the mass (in grams) corresponding to 1.28 × 10⁻⁵ moles of TiO₂

To convert moles to mass, we need a conversion factor. In this case, it is the molar mass of TiO₂: 79.87 g/mol.

1.28 × 10⁻⁵ mol TiO₂ × 79.87 g TiO₂/1 mol TiO₂ = 1.02 × 10⁻³ g TiO₂

Identify two ways that temperature plays a role in chemical changes.

Answers

Answer:

Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.

Answers

Answer:

B. Dispose of pH paper in the trash.

C. Dump the cabbage indicator solution down the drain.

D. Ask your teacher to neutralize the acids and bases before disposal.

Explanation:

Safe disposal of waste means disposal of waste in such a way that it does not pose a threat to the environment.

When pH paper is properly disposed in the trash, it does not constitute any risk to the environment.

When a cabbage indicator solution is disposed down the drain it does not contaminate the environment. It moves directly into the sewers and is properly disposed.

When acids and bases are properly neutralized before disposal, they don't lead to acid or base contamination of the environment.

What are fossil fuels?

Fossil fuels are compound mixtures made of fossilized plant and animal remnants from millions of years ago. The creation of fossil fuels—either oil, natural gas, or coal—from these fossils is determined by the type of fossil, the amount of heat, and the amount of pressure.

Fossil fuels are a non-renewable source of energy. Most of the energy used by us is obtained by the burning of fossil fuels. These fossil fuels are used up at a faster rate. They cannot be regrown at a scale compared to their consumption.

Therefore, Copper is not a fossil fuel and the correct option is option 1.

What mass of potassium would need 2350 J of energy in order to raise its temperature from 44.3°C to 57.8°C? (cpotassium = 0.753 J/g°C)

Answers

Answer:

Explanation:

q = mCΔT

m =CΔT/q

ΔT = 57.8°C - 44.3°C = 13.5°C

m = (0.753*13.5)/2350

m = 0.00433 g

The mass of potassium that will need 2350 J of energy in order to raise its temperature from 44.3°C to 57.8°C is 231.17 g

Data obtained from the question Heat (Q) = 2350 JInitial temperature (T₁) = 44.3 °CFinal temperature of water (T₂) = 57.8 °CChange in temperature (ΔT) = 57.8 – 44.3 = 13.5 °C Specific heat capacity (C) = 0.753 J/gºC Mass (M) =?

Q = MCΔT

2350 = M × 0.753 × 13.5

2350 = M × 10.1655

Divide both side by 10.1655

M = 2350 / 10.1655

How many protons, neutrons, and electrons are found in a neutral atom of hydrogen-333?

Answers

Answer:

Explanation:

A hydrogen atom has an atomic number of 1.

So it's proton number will always be 1.

A neutral hydrogen atom does not have any charge.

So it has the same amount of electrons as protons, which turns out to be also 1.

A neutral hydrogen atom has an atomic mass of ≈

1.00794 amu ≈ 1 amu.

To find the amount of neutrons, we take the proton number and subtract it from the mass number.

1 − 1 = 0

So a neutral hydrogen atom has no neutrons.

In summary,

A hydrogen atom has

1 proton

1 electron

0 neutrons

Find the total pressure (in atm) of a mixture that contains 3 gases with the following partial pressures. Gas A is 4.2atm, Gas B is 780 mmHg, Gas C is 250.00kPa

Answers

Answer: The total pressure of given mixture that contains 3 gases is 7.68 atm.

Explanation:

Given: Partial pressure of gases is:

Gas A = 4.2 atm

Gas B = 780 mm Hg

Convert mm Hg into atm is as follows.

[tex]1 mm Hg = 0.00131579 atm\\780 mm Hg = 780 mm Hg \times \frac{0.00131579 atm}{1 mm Hg}\\= 1.02 atm[/tex]

Gas C = 250 kPa

Convert kPa into atm as follows.

[tex]1 kPa = 0.00986923 atm\\250 kPa = 250 kPa \times \frac{0.00986923 atm}{1 kPa}\\= 2.46 atm[/tex]

Total pressure is the sum of partial pressures of gases present in the mixture.

Therefore, total pressure of given mixture is calculated as follows.

[tex]P_{total} = P_{A} + P_{B} + P_{C}\\= 4.2 atm + 1.02 atm + 2.46 atm\\= 7.68 atm[/tex]

Thus, we can conclude that the total pressure of given mixture that contains 3 gases is 7.68 atm.

1. If you have 8.1 g CO₂ and 2.3 g H₂, which one is the limiting reactant. Show your work. 2. Calculate the theoretical yield of CH₄.

Answers

Answer:

2.95 g of CH₄

Explanation:

To start this, we determine the equation:

4H₂  + CO₂ →  CH₄  +  2H₂O

4 moles of hydrogen react to 1 mol of carbon dioxide in order to produce 1 mol of methane and 2 moles of water.

To determine the limiting reactant, we need to know the moles of each reactant.

8.1 g . 1 mol/ 44g = 0.184 moles of carbon dioxide

2.3 g . 1mol / 2g = 1.15 moles of hydrogen

4 moles of hydrogen react to 1 mol of CO₂

Then, 1.15 moles may react to (1.15 . 1) /4 = 0.2875 moles

We only have 0.184 moles of CO₂, so this is the limiting reactant. Not enough CO₂ to complete the 0.2875 moles that are needed.

Ratio is 1:1. 1 mol of CO₂ produces 1 mol of methane

Then, 0.184 moles of CO₂ will produce 0.184 moles of CH₄

We convert moles to mass: 0.184 mol . 16 g /mol = 2.95 g

A 280.0 sample of neon gas exerts a pressure of 660.0 mm Hg at 26.0°C. Assuming that the pressure remains constant, at what temperature in would the volume change to 440.0 ml?

Answers

Answer:

469.9K

Explanation:

Using Charles's law equation:

V1/T1 = V2/T2

Where;

V1 = initial volume (ml)

V2 = final volume (ml)

T1 = initial temperature (K)

T2 = final temperature (K)

Based on the information provided:

V1 = 280.0ml

V2 = 440.0 ml

T1 = 26.0°C = 26 + 273 = 299K

T2 = ?

Using V1/T1 = V2/T2

280/299 = 440/T2

0.936 = 440/T2

T2 = 440 ÷ 0.936

T2 = 469.9K

Using the law of conservation of mass, the mass of carbon reacted is 54 g of carbon.

What is the law of conservation of mass?

According to the law of conservation of mass, matter is neither created nor destroyed. This means that the total mass of reactants is equal to the total mass of products.

Total mass of the products = 336g + 198g = 534 g

Total mass of reactants = 480 g + x g

From the law of conservation of mass;  534 g = 480 g + x g

x g = 534 g - 480 g

x g = 54 g

Hence, 54 g of carbon reacted.
