Energy is required to break chemical bonds, and energy is released when bonds
form. How does this observation help explain the energy released by burning Food?
Answer:
See below.
Explanation:
Since energy is released when bonds form, the process of burning food can be explained through exothermic reactions. We use food as a resource to obtain energy through calories, where the chemicals that makeup food result in endothermic reactions to fulfill our dietary needs. As a result, that energy MUST be released since energy can neither be created nor destroyed. Therefore, it must come out as the bonds are broken (usually hydrogen bonds during the process of cellular respiration). While calories are being burned, energy is released, causing bonds to break and resulting in exothermic reactions.
What can decrease the amount of CO2 being removed from the atmosphere
Reduce Vehicle Emissions decrease the amount of CO2 being removed from the atmosphere
Many of us drive cars every day, which are one of the greatest sources of CO2 in our environment. With a share of 31% of all emissions, this is the second-largest source of carbon dioxide produced in the US. However, this is not simply restricted to personal vehicles; anything that has an engine powered by gasoline or diesel contributes to this issue.
Limiting the quantity of CO2 your own car emits is the best personal solution to this problem. To make all of your journeys a little less wasteful, choose a hybrid or gas-efficient car.

what is the molarity of 125 g cobalt chloride dissolved in a final volume of 300 ml? the fw is 237.9 g/mol.
The formula weight is 237.9 g/mols the molarity of 125 g cobalt chloride dissolved in a final volume of 300 ml.
What is molarity ?The word "molar concentration" refers to the amount of a substance per unit volume of solution and is used to describe the concentration of a chemical species, specifically a solute, in a solution. Molarity, amount, and substance concentration are other names for this term. The number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units, is the molarity unit that is most frequently used in chemistry. The term "molar," often known as "1 M," refers to a solution with a concentration of 1 mol/L.
As a result of thermal expansion, the volume of most solutions varies slightly with temperature in thermodynamics, making it difficult to employ molar concentration. The typical solution to this issue is to use a temperature-independent metric or to introduce temperature correction variables.

how many grams of oxygen are required to react with 14.0 grams of octane ( c8h18 ) in the combustion of octane in gasoline?
48.64 grams of oxygen are required to react with 14.0 grams of octane (C₈H₁₈) in the combustion of octane in gasoline.
To find the oxygen required, the given data's are:
Mass of octane = 14 grams.
What is octane?Octane is a hydrocarbon which burns in gasoline in presence of oxygen.
According to the given balanced chemical equation,
C₈H₁₈ + 25/2O₂ → 8CO₂ +9H₂O or
2C₈H₁₈ + 25O₂------> 16CO₂ + 18H₂0
At first to find the moles of octane,
Molar mass of octane = 114.2 g/mol,
The mole of octane can be calculated as,
Moles = grams / Molar mass
= 14g / 114.2 g/mol
= 0.122 mol.
The moles of octane is 0.122 mol.
Using mole ratio from the balanced equation to find moles of O₂,
The mole ratio of octane and O₂ is 2 : 25. Let us use this as a conversion factor.
0.122 mol C₈H₁₈ × ( 25 mol O2/ 2 mol C₈H₁₈)
= 0.122 × 12.5
= 1.525 mol
We have 1.525 mol O₂.
Now, Converting moles of O₂ to grams,
The molar mass of O₂ is 32 g/mol.
The grams of O₂ can be calculated as,
1.525 mol × 32 g/mol = 48.64 grams.
48.64 grams of oxygen are required.
Hence, 48.64 grams of oxygen are required to react with 14.0 grams of octane ( C₈H₁₈ ) in the combustion of octane in gasoline.

The most negative electron affinity is most likely associated with small nonmetal atoms.
Electron affinity is the amount of energy released when an electron is added to an isolated gaseous atom.
When the first electron is added to a neutral atom, the electron affinity is positive. However, when a second electron is added to an anion, the electron affinity becomes positive due to the repulsion of electrons.
The electron affinity of non-metals is greater than metals because non-metals gain electrons whereas metals accept an electron. Due to this, electron affinity increases from left to right in a period.

We'll begin by calculating the amount of mole of in 3.046 g of precipitate, Ba₂SO₄
Molar mass of Ba₂SO₄ = (2×137) + 32 + (4×16) = 370 g/mol
Mass of Ba₂SO₄ = 3.046 g
Mole of Ba₂SO₄ =?
Mole = mass /molar mass
Mole of Ba₂SO₄ = 3.046 / 370
Mole of Ba₂SO₄ = 0.008 mole

The entropy is known to increase because of the pressure or concentration is reduced. Entropy of gases are much larger than the condensed phases.
Entropy is the measure of the randomness or disorder of the system.
When the gas molecules were in an enclosed chamber, they were at a constant temperature and molecules did not slow down but when they were allowed to enter a second chamber, they had more place in container where they were in disorder, which resulted in redistribution of gas molecules, increasing the entropy of gas due to its expansion.
