Answers

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.

If I have 6 moles of a gas at a pressure of 10.6 atm and a volume of 48 liters, what is the temperature of this gas?
An unknown quantity of gas is at a pressure of 14.5 atm, a volume of 45 liters, and a temperature of 97 0C, how many moles of gas exist in this situation?

Answers

Answer: 1). The temperature of this gas is 1032.88 K.

2). There are 21.48 moles of gas exist at a pressure of 14.5 atm, a volume of 45 liters, and a temperature of [tex]97^{o}C[/tex].

Explanation:

1). Given: No. of moles = 6 moles

Pressure = 10.6 atm

Volume = 48 L

Formula used to calculate temperature is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 atm

T = temperature

Substitute the values into above formula as follows.

[tex]PV = nRT\\10.6 atm \times 48 L = 6 mol \times 0.0821 L atm/mol K \times T\\T = \frac{10.6 atm \times 48 L}{6 mol \times 0.0821 L atm/mol K}\\= \frac{508.8}{0.4926} K\\= 1032.88 K[/tex]

Hence, temperature of this gas is 1032.88 K.

2). Given: Pressure = 14.5 atm

Volume = 45 L

Temperature = [tex]97^{o}C = (97 + 273) K = 370 K[/tex]

Formula used to calculate number of moles is as follows.

[tex]PV = nRT\\14.5 atm \times 45 L = n \times 0.0821 L atm/mol K \times 370 K\\n = \frac{14.5 atm \times 45 L}{0.0821 L atm/mol K \times 370 K}\\= \frac{652.5}{30.377} mol\\= 21.48 mol[/tex]

Hence, there are 21.48 moles of gas exist at a pressure of 14.5 atm, a volume of 45 liters, and a temperature of [tex]97^{o}C[/tex].

Birds use their feathers for flight and fluff their feathers to keep warm. Based on Natalia's feather experiment, how do oil spills affect birds’ ability to use their feathers?

Answers

A new study finds that even small smudges of oil can have huge impacts on flight and a bird's energy budget. ... For seabirds, oil can sink their natural buoyancy and literally drag them into a watery grave. And the birds that try to clean themselves ingest a sticky poison that ravages their livers, lungs, and intestines.

Answer:

As shown previously on Natalia's experiment, oil spills will dangerously affect birds' abilities to user their feathers. When oil gets on a feather, the mass of it increases and it becomes soggy and wet. If birds try to go in water like the ocean, it will not get any better because the ocean is cold. Flying won't be easy because they have additional weight stuck to them.

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

Answers

Answer:

Explanation:

coal, petroleum, and natural gas are all related to fossil fuels.

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

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.

In a chemical reaction, the atoms and molecules that interact with each other are called reactants.

In a chemical reaction, the atoms and molecules produced by the reaction are called products.

In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed.

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.

How many moles of NO are made from
mixing 7.2 moles of NH3 and 9.6 moles
of O? Identify the limiting reagent.

Answers

Answer:

216 g of NO

Explanation:

We begin from the reaction:

4NH₃ + 5O₂ →  4NO  + 6H₂O

We determine the limiting reactant with the moles of each reactant:

4 moles of ammonia react to 5 moles of oxygen

Our 7.2 moles of ammonia may react to (7.2 . 5) /4 = 9 moles

It's ok because we have 9.6 moles of oxygen. 0.6 moles still remain.

5 moles of oxygen react to 4 moles of NH₃

Our 9.6 moles of oxygen may react to (9.6 . 4) /5 = 7.68 moles

We only have 7.2 moles of NH₃ and we need 7.68; so there is no enough ammonia and that's our limiting reagent.

Now we determine the moles of product.

4 moles of ammonia can produce 4 moles of NO

Definetely our 7.2 moles, will produce 7.2 moles of oxide.

We convert to mass: 7.2 mol . 30 g/mol = 216 g
