The ratio of octene to oxygen is 1:12.

To determine the ratio of octene (C8H16) to oxygen (O2) in the given reaction, we need to examine the balanced chemical equation. However, the equation you provided does not seem to be balanced. The coefficients for each compound must be determined to achieve a balanced equation before we can calculate the desired ratio.

Assuming you meant the combustion reaction of octene, a balanced equation would be:

C8H16 + 12O2 → 8CO2 + 8H2O

From the balanced equation, we can see that for every 1 mole of octene (C8H16), we require 12 moles of oxygen (O2) to completely react.

This means that for every 1 mole of octene, we need 12 moles of oxygen to fully combust the octene and produce the corresponding amounts of carbon dioxide (CO2) and water (H2O) as shown in the balanced equation.

The mass of 4.00 × 10^22 helium atoms is approximately 0.265 grams.

To determine the mass of 4.00 × 10^22 helium atoms, we need to know the molar mass of helium, which is 4.0026 g/mol. The molar mass represents the mass of one mole of helium atoms.

To calculate the mass of a given number of helium atoms, we can use the following steps:

Convert the given number of helium atoms to moles:

Moles = Number of atoms / Avogadro's number

Moles = 4.00 × 10^22 atoms / 6.022 × 10^23 atoms/mol

Calculate the mass using the molar mass of helium:

Mass = Moles × Molar mass

Mass = Moles × 4.0026 g/mol

Now, substituting the values:

Moles = (4.00 × 10^22 atoms) / (6.022 × 10^23 atoms/mol) ≈ 0.0663 mol

Mass = (0.0663 mol) × (4.0026 g/mol) ≈ 0.265 g

Therefore, the mass of 4.00 × 10^22 helium atoms is approximately 0.265 grams.

Answer: Its B for the Study Island assignment

Explanation:

Answer:

To find the least soluble substance at a given temperature we follow the temperature line up and the first substance curve we hit is the least soluble. For most soluble it is the same procedure except the last substance curve hit is the most soluble.

To determine if a substance is more soluble or less soluble based on a solubility curve, you need to compare the solubility values at different temperatures. Here's how you can interpret a solubility curve:

1. Higher Points on the Curve: If a point on the curve is higher, it indicates that the substance is more soluble at that temperature. In other words, at higher temperatures, the substance can dissolve in a greater amount.

2. Lower Points on the Curve: If a point on the curve is lower, it means that the substance is less soluble at that temperature. In this case, at lower temperatures, the substance can dissolve in a smaller amount.

3. Comparing Points: By comparing the solubility values at different temperatures, you can determine which temperature has a higher solubility and which has a lower solubility. The steeper the slope of the curve, the faster the increase or decrease in solubility with temperature.

Solubility curves provide a graphical representation of the relationship between temperature and solubility. They allow you to determine the solubility characteristics of a substance and how it changes with temperature.

Magnesium have two valence electrons. Because the outer energy level  for the magnesium atom is 3 and it has two electron in this energy level.

The Valence electrons are defined as the electrons that located in the outermost electron shell of an atom. These valence electrons being the furthest from the nucleus and thus the least tightly held by the atom are the electrons that participate in bonds and reactions. The number of valence electrons that an element has determines its reactivity, electronegativity and the number of bonds it can form. We can use the periodic table to help to determine how many valence electrons an element specifically a neutral atom of the element has. Looking at the group that the element is in as the group number indicates the number of valence electrons that the element has.

When the gas is heated from -50°C to 28°C, the new volume is approximately 17.24 L.

To calculate the new volume of a gas when it is heated from -50°C to 28°C, we can use the combined gas law, which relates the initial and final conditions of temperature and volume.

The combined gas law is expressed as:

(P1 * V1) / T1 = (P2 * V2) / T2

Where:

P1 = Initial pressure

V1 = Initial volume

T1 = Initial temperature in Kelvin

P2 = Final pressure (assumed constant in this case)

V2 = Final volume (to be calculated)

T2 = Final temperature in Kelvin

First, we need to convert the initial and final temperatures from Celsius to Kelvin:

Initial temperature in Kelvin (T1) = -50°C + 273.15 = 223.15 K

Final temperature in Kelvin (T2) = 28°C + 273.15 = 301.15 K

Since the pressure is assumed to be constant, we can simplify the equation:

(V1 / T1) = (V2 / T2)

Now we can substitute the given values into the equation:

(12.78 L / 223.15 K) = (V2 / 301.15 K)

Cross-multiplying and solving for V2:

V2 = (12.78 L * 301.15 K) / 223.15 K

V2 ≈ 17.24 L

The estimated age of the archaeological plant-based sample is approximately 1912 years.

1. Understand that decay refers to the process where the radioactive isotopes, such as 14C, break down over time, and half-life refers to the time it takes for half of the radioactive isotopes to decay.

2. Given that the 14C decay rate in the archaeological sample is 81.0% of the decay rate in a living plant, this means that the sample has 0.81 times the amount of 14C as a living plant.

3. Since the half-life of 14C is 5730 years, you can use the decay formula to calculate the age of the sample:

N = N0 * (1/2)^(t / half-life)

where N is the final amount of 14C, N0 is the initial amount, t is the age of the sample, and half-life is the half-life of 14C (5730 years).

4. Plug in the values given:

0.81 = 1 * (1/2)^(t / 5730)

5. Solve for t:

t / 5730 = log(0.81) / log(0.5)
t = 5730 * (log(0.81) / log(0.5))
t ≈ 1912 years
