On a 310 K day, soda is being carbonated in a factory.
a. A 0.031 m
pressure device receives a measurement of 9900 N from the gases in
the soda bottle. What is the pressure of the gases in the soda bottle?

b. Since soda contains water, 47.1 mm Hg of the pressure in the bottle is from water
vapor. What is the pressure of the Co2 in the bottle?

c. Before the CO2 is added to the soda, it's stored in a 1849 L container at 50 atm
and 310 K.

i. How many moles of CO, can fit in the container?

ii. Unfortunately, an accident (blame Steve), dents the container, reducing its
volume to 1399 L. If the number of moles and temperature are still
constant, what is the new pressure?

iii. The factory repairs the container so it's back to its original conditions.
However, the container is weakened, so if the pressure reaches 75 atm it
will burst. If the number of moles and volume are constant, at what
temperature does this burst happen?

Answer:

Explanation:

Cuz the color is a light yellow and water to make it loose color

The mixing of two different liquids together to form a new mixture is called a solution.

The correct option is acid.

In a solution, there are two components which are known as solute and solvent. In which solute is less in amount and solvent is more in an amount which is water.

According to the question, the smoothie turns the color to pink from purple because lemon act as an acid and changes the ph of the solution.

Hence, the Lemon act as an acid.

Unbalanced forces are forces whose net amount is not zero.

This can take place when two equal forces are acting in the same direction or opposite direction but with different forces.

Unbalanced forces make some change in the position of the object on which force is exerted.

Answer:

C producers

Explanation:

All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.

Answer:

because time do not depend on direction. actually time is fake.nobody can stop it neither disturb it.it is in my view.

Lowering the pressure in a container will cause the liquid in the container to boil faster because it becomes easier for the molecules to escape.

Boiling happens when the vapor pressure of a liquid equals the atmospheric pressure.

By lowering the atmospheric pressure, the vapor pressure of a liquid takes a lower time to equal the atmospheric pressure.

Thus, it becomes easier for the molecules of the liquid to escape from each other.

Answer:

Polar molecules have a non-zero net dipole moment. Both CO2 and H2O have two polar bonds. However the dipoles in the linear CO2 molecule cancel each other out, meaning that the CO2 molecule is non-polar. The polar bonds in the bent H2O molecule result in a net dipole moment, so H2O is polar.

Answer:

26.0 moles

Explanation:

Given the formula;

PV =nRT

P= pressure of the gas

V = volume of the gas

n = number of moles of the gas

R = gas constant

T = temperature

n = PV/RT

n = 125 * 5/0.082 * (20 + 273)

n = 625/24.026

n = 26.0 moles

B : 4.6 billion years

Credits go to the person above me.

;)

Explanation:

EDGE 2021

The sun is about 4.6 billion years old. Therefore, option (B) is correct.

The Sun is made primarily of the elements hydrogen and helium. They account for 74.9% and 23.8% mass of the Sun in the photosphere. All heavier elements, called metals account for less than 2% of the mass, with oxygen (<1%), carbon (0.3%), neon (0.2%), and iron (0.2%) being the most abundant.

The hydrogen and helium in the Sun would have been produced by Big Bang nucleosynthesis and the heavier elements were produced by former generations of stars before the Sun was formed.

The amount of helium and its location within the Sun has gradually changed over the past 4.6 billion years. The proportion of helium has raised from about 24% to 60% due to fusion, and some of the He and heavy elements have settled from the photosphere toward the center due to gravity.

Therefore, the age of the sun is about 4.6 billion years.

Explanation:

KCl - the flame test for Potassium produces a lilac flame

The metal in the salt has been potassium, and the salt has been KCl. Thus, option C is correct.

The flame test has been performed with the burning of the salt under the flame. The electrons of the elements after gaining the energy have been excited to the higher energy level.

There has been the returning of the electrons to the ground state. In the process. the absorbed energy has been released in the form of visible radiations. The determination of the radiations results in the determination of the metal, as each metal has a unique flame.

The burning of the salt results in the lilac flame. The flame has resembled the burning of potassium. Thus, the metal in the salt has been potassium, and the salt has been KCl. Thus, option C is correct.

Answer:

7.30g O₂ are in excess and 21.3g of SO₂ should be produced.

Explanation:

The reaction of Zinc sulfide (ZnS) with oxygen (O₂) produce ZnO and SO₂ as follows:

2ZnS + 3O₂ → 2ZnO + 2SO₂

Using this reaction we can find the amount of SO₂ produced converting the ZnS and O₂ to moles and finding limiting and excess reactant as follows:

Moles ZnS -Molar mass: 97.47g/mol-:

32.5g * (1mol / 97.47g) = 0.333 moles ZnS

Moles O₂ -Molar mass: 32g/mol-:

23.3g O₂ * (1mol / 32g) = 0.728 moles O₂

For a complete reaction of the 0.333 moles of ZnS are required:

0.333 moles ZnS * (3mol O₂ / 2mol ZnS) = 0.500 moles O₂.

As there are 0.728 moles of O₂, limiting reactant is ZnS and excess reactant is O₂.

The moles and mass of O₂ in excess are:

0.728mol - 0.500mol = 0.228moles O₂ * (32g / mol) = 7.30g O₂ are in excess

The produced mass of SO₂ -Obtained from the moles of ZnS- is:

0.333 moles of ZnS * (2mol SO₂ / 2mol ZnS) = 0.333 moles SO₂

0.333 moles SO₂ * (64.066g / mol) =

Answer:

1.33 x 10^-3 mol H2

Explanation:

? mol H2 = 8.00 x 1020^20 molecules H2 x  1 mol H2/6.02 ! 1023 molecules H2 = 1.33 x 10^-3 mol H2

Hope that helps!

8.00 x 10²⁰ molecules of H₂ present in 1.33 x 10⁻³ mole of H₂.

Mole is used to define the amount of quantity of any substance and 1 mole equals to the 6.023 × 10²³ elementary entities or atoms in it.

According to the question:

1 mole of H₂ = 6.023 × 10²³ molecules of H₂

or 1 molecules of H₂ = 1 mole of H₂ / 6.023 × 10²³ molecules of H₂

To convert 8.00 x 10²⁰ molecules into mole we calculate as follow:

x mole of H₂ = (8.00 x 10²⁰ molecules x  1 mole of H₂) / 6.023 × 10²³ molecules

x mole = 1.33 x 10⁻³ mole

Hence, 1.33 x 10⁻³ mole of H₂ consist 8.00 x 10²⁰ molecules.
