The x axis is the number of chips while the variable that should be plotted on the y axis is the total mass.

The graph refers to a means of presenting data on cartesian coordinates. The Cartesian coordinates are x and y. We know that traditionally, the independent variable goes to the x axis while the dependent variable goes to the y axis.

If we have the variables as number of chips and total mass, the variable that should be plotted on the x axis is the number of chips while the variable that should be plotted on the y axis is the total mass.

Answer:

3

Explanation:

at first try balancing the carbon first. At first multiply 2 with CO2, that produces 2 carbon and 8 oxygen. On reactant side we have 3 Oxygen. Now look at Hydrogen. There are 6 hydrogen atoms on the reactant side. So you need to multiply 3 with H20 to be 6 hydrogen atoms as 3*2 = 6.

Final reaction: C2H5OH + 3O2 ------> 2CO2 + 3H2O

So, a full moon rises early in the night and sets early in the morning, it is visible all night long. Contrarily, a new moon rises early in the morning (with the sun) and sets at night (with the sun), and is not visible at night, at all.

Hope that helps!

Answer:

because

Explanation:

A new moon is visible only during a solar eclipse.They are rarely seen.

The Full Moon is visible in the sky approximately from sunset to sunrise.

In order to appear full to us on Earth, we have to see the entire day side of the moon.

That happens only when the moon is opposite the sun in our sky. So a full moon looks full because it's opposite the sun

This question lacks options, the options are:

A). synthesizes more sugar

B). has a higher chromosome count

C). produces fewer proteins

D). uses less carbon dioxide

The answer is A

Explanation:

The chloroplast is an organelle present in the cells of photosynthetic organisms. It is the site where photosynthesis, which is the production of food (sugars) from sunlight energy, occurs.

According to this question, a cell in the leaf of a corn plant contains more chloroplasts than a cell in the stem of the same corn plant. Based on this observation, it can be inferred that the LEAF CELLS WILL SYNTHESIZE MORE SUGARS THAN THE STEM CELL because the more the chloroplast, the higher the photosynthetic rate and subsequently the higher the amount of sugar produced.

To name Type 2 ionic compounds such as AuCl₃, you need to use the Stock system or Roman numeral system to indicate the oxidation state of the cation. Some steps are; Identify the cation, Determine the charge, Write the name, and combine two names.

Here are the steps to name AuCl₃; Identify the cation and anion. In this case, the cation is Au³⁺ and the anion is Cl⁻.

Determine the charge on the cation by using the anion's charge and balancing the charges to zero. Since Cl⁻ has a charge of -1 and there are three Cl⁻ ions in the compound, the total negative charge is -3. Therefore, the Au³⁺ ion has a charge of +3.

Write the name of the cation first, followed by the name of the anion with an -ide ending. Since the cation is Au³⁺, we use the name "gold(III)" to indicate the oxidation state of +3. The anion is Cl⁻, so we add the -ide ending to get "chloride".

Combine the two names to get the compound's name: "gold(III) chloride".

Therefore, the name of the Type 2 ionic compound AuCl₃ is "gold(III) chloride".

At equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

1: Write the balanced chemical equation:

\(C_O\)(g) + \(Cl_2\)(g) ⟶ \(C_OCl_2\)(g)

2: Set up an ICE table to track the changes in moles of the substances involved in the reaction.

Initial:

\(C_O\)(g) = 0.3500 mol

\(Cl_2\)(g) = 0.05500 mol

\(C_OCl_2\)(g) = 0 mol

Change:

\(C_O\)(g) = -x

\(Cl_2\)(g) = -x

\(C_OCl_2\)(g) = +x

Equilibrium:

\(C_O\)(g) = 0.3500 - x mol

\(Cl_2\)(g) = 0.05500 - x mol

\(C_OCl_2\)(g) = x mol

3: Write the expression for the equilibrium constant (Kc) using the concentrations of the species involved:

Kc = [\(C_OCl_2\)(g)] / [\(C_O\)(g)] * [\(Cl_2\)(g)]

4: Substitute the given equilibrium constant (Kc) value into the expression:

1.2 x \(10^3\) = x / (0.3500 - x) * (0.05500 - x)

5: Solve the equation for x. Rearrange the equation to obtain a quadratic equation:

1.2 x \(10^3\) * (0.3500 - x) * (0.05500 - x) = x

6: Simplify and solve the quadratic equation. This can be done by multiplying out the terms, rearranging the equation to standard quadratic form, and then using the quadratic formula.

7: After solving the quadratic equation, you will find two possible values for x. However, since the number of moles cannot be negative, we discard the negative solution.

8: The positive value of x represents the number of moles of \(Cl_2\)(g) at equilibrium. Substitute the value of x into the expression for \(Cl_2\)(g):

\(Cl_2\)(g) = 0.05500 - x

9: Calculate the value of \(Cl_2\)(g) at equilibrium:

\(Cl_2\)(g) = 0.05500 - x

\(Cl_2\)(g) = 0.05500 - (positive value of x)

10: Calculate the final value of \(Cl_2\) (g) at equilibrium to get the answer.

Therefore, at equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

Answer:uses world like

Explanation:

Answer:

The correct answer is 12.58 grams.

Explanation:

Based on the given information, the electrolysis equation will be,

Al³⁺ + 3e⁻ ⇔ Al

1 mol of Al needs 3 moles of electron, and the value for 1 mole of electron is 96485 C.

Thus, 1 mole of Al needs 3 × 96485 C = 289455 C

Now the amount of charge passed is,

T = 2.5 hours

= 2.5 × 3600 s = 9 × 10³ s

Q = Current × Time

= 15A × 9 × 10³ s

= 13.5 × 10⁴ C

The moles of Al plated will be,

= 13.5 × 10⁴ / 289455

= 0.4664 mol

The molecular mass of Al is 26.98 grams per mole

Now the mass of Al will be,

= Number of moles × Molecular mass

= 0.4664 × 26.98

= 12.58 grams

The equilibrium expression can be written as follows:

K = [CaCO₃] × [H₂]⁴

------------------

[CaO] × [CH₄] × [H₂O]²

In this equilibrium expression, the square brackets represent the concentrations of the species involved in the reaction, and the coefficients of the balanced equation indicate the stoichiometric coefficients of the corresponding species.

The concentration of a pure solid (CaCO₃ in this case) is not included in the equilibrium expression, as it remains constant throughout the reaction.

The equilibrium constant (K) represents the ratio of the product concentrations to the reactant concentrations at equilibrium, each raised to the power of their respective stoichiometric coefficients. The specific values of these concentrations depend on the initial conditions, and K remains constant as long as the temperature is unchanged.

It is important to note that the equilibrium constant expression is written based on the balanced chemical equation. The stoichiometric coefficients determine the relationship between the concentrations of reactants and products, allowing us to express the equilibrium state quantitatively using the equilibrium expression.

The term that refers to the passing of a wave through an object is "transmission."

Transmission refers to the process by which a wave passes through an object or medium. In the context of sound, transmission occurs when sound waves travel through different substances, such as air, water, or solids.

When a sound wave encounters an object, it can be transmitted through it, reflected off it, or absorbed by it, depending on the properties of the object and the medium through which the sound is traveling.

For example, when you speak into a microphone, the sound waves produced by your voice travel through the air and are transmitted to the microphone's diaphragm. The diaphragm converts the sound waves into electrical signals, which can then be amplified and reproduced as sound through speakers.

In summary, transmission is the term used to describe the passage of a wave, such as a sound wave, through an object or medium. It is an essential concept in understanding how waves interact with their surroundings and how sound propagates through different materials.

The force of gravity needed to make a 13kg ball fall on Earth is 127.53N.

Force of gravity is a force that attracts any two objects with mass. The force of gravity is the weight of an object on Earth.

The weight of the force on an object due to the gravitational attraction between it and the Earth (or whatever astronomical object it is primarily influenced by).

The weight of an object can be calculated by multiplying the force of the object by acceleration due to gravity on Earth as follows:

Weight = force × 9.81m/s²

Weight = 13kg × 9.81m/s²

Weight = 127.53N.
