There are 67.3 grams of water (a), the percentage of fat is 25.2%  (b), the percentage of water is  53.84% (c), the percentage of protein is 20.96%(d), and there are grams of fat  44.22 grams(e).

26.2 + 31.5 = 57.7 - 125 = 67.3 grams of water

Knowing the total 125 represents 100%, let's calculate the percentages:

Fat: 31.5 x 100 /125 = 25.2%

Protein: 26.2 x 100 / 125 = 20.96%

Water: 67.3 x 100 / 125 = 53.84%

6.2 ounces = 175.76 grams (1 ounce = 28.34 grams)

The bioplastics at room temperature have better flexibility than they have at the refrigerator temperature. The chain mobility of the polymer reduces at lower temperature.

Bioplastics are biodegradable polymers. The sugar found in plants is converted into plastic to create bioplastics. In the US, corn is the source of that sugar.

Because of this, bioplastics are more environmentally friendly and renewable than traditional plastics. Currently, a substantial amount of bioplastics are manufactured in two different forms.

They are referred to as polyhydroxyalkanoate (PHA) and polylactide acid (PLA) (PHA). Blair, Nebraska-based Nature Works is the largest PLA manufacturer. These polymer chains are flexible at room temperature however, the chain mobility gets hindered at very lower temperature and their flexibility decreases.

When 0.75 mol O₂ reacts with iron, it will produce 1.5 moles of Fe₂O3.

Moles are small, burrowing mammals found throughout much of the world. They have a cylindrical body, covered in short, velvety fur, and stocky legs. They have a rounded snout and small eyes, and their fur is usually black, brown, or gray. Moles feed mainly on earthworms, insects, and grubs, and use their powerful front paws to dig extensive tunnel systems in gardens and lawns. Moles are solitary creatures, living and foraging alone, and they are active both day and night.

This is because the balanced chemical equation for the reaction is: 2Fe + 3O₂ → Fe₂O₃. Since there is a 2:3 ratio of iron atoms to oxygen atoms, for every 0.75 moles of oxygen, 1.5 moles of Fe₂O₃ will be produced.

Energy is absorbed from the surroundings to break bonds is the statements about a chemical reaction or endothermic is correct.

The process of breaking bonds is termed as endothermic. When new bonds are formed, energy is released. The process of creating bonds is exothermic. The difference between the energy required for breaking a bonds and the energy released while the new bonds form determines whether a reaction may be defined as endothermic or exothermic.

Option (C) is correct. The phase of a substance depends on the relative magnitudes of the molecular Kinetic energy and the energy of intermolecular attractions.

The phase of a substance depends on the balance between the kinetic energy of the individual particles and the intermolecular forces. The kinetic energy keeps the molecules apart and keeps moving around. That is the function of the temperature of the substance and the intermolecular forces try to draw the particles together. The kinetic energy is defined as the energy that possesses due to the motion of an object. This energy is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

In this system, the reactants A and B will react to form the product AB until the system reaches equilibrium.

This means that the rate of the forward reaction will equal the rate of the reverse reaction. Additionally, the equilibrium constant, Kc, can be used to calculate the amount of the products and reactants at equilibrium.

The equilibrium constant, Kc, is used to calculate the relative amounts of products and reactants at equilibrium. It is calculated by taking the product of the concentrations of the products raised to their respective stoichiometric coefficients and dividing it by the product of the concentrations of the reactants raised to their respective stoichiometric coefficients. This equation looks like this:

Kc = (Products)^(Stoichiometric Coefficients) / (Reactants)^(Stoichiometric Coefficients)

For example, if we have the reaction A + B → AB, Kc can be calculated as follows:

This equation states that the equilibrium constant, Kc, is equal to the concentration of AB divided by the product of the concentrations of A and B.

The light colored panel reflects light and heats up, while the dark colored panel absorbs the light and stays cooler. This temperature difference causes the vanes to spin.

The dark panel absorbs the incoming light, while the light panel reflects it. Due to this, the two panels' temperatures differ, with the dark panel becoming hotter than the light panel.

Due to the pressure difference caused by the temperature difference, air molecules move from the hot, dark panel to the cool, light panel. The radiometer's associated vanes spin as a result of this air flow.

The radiometer will spin more quickly the greater the temperature differential between the two panels. The temperature differential between the two panels is higher in a vacuum, enabling the radiometer to spin more quickly.

Answer:

The reason for this is likely an exothermic reaction, where the combination of substances A and B results in a release of heat energy.

Explanation:

An exothermic reaction is a chemical reaction that releases heat energy. This heat can cause an increase in temperature, sometimes to a point where it becomes uncomfortable or even dangerous to touch the mixture. The exact reason why the mixture becomes hot depends on the chemical nature of substances A and B and the reaction they undergo when mixed. Some possible causes could include an increase in the rate of molecular motion as the reaction progresses, or the breaking and formation of chemical bonds, which releases energy in the form of heat. Additionally, the reaction could be releasing gases that are expanding and generating heat as a result. To determine the exact cause, a detailed analysis of the chemical composition and reaction kinetics of the mixture would be required.

Below are the three true assertions concerning autotrophs and heterotrophs on earth.

In order to support aerobic respiration, heterotrophs depend on autotrophs to produce O2 from H2O. They also depend on autotrophs to convert light energy to chemical energy. The bulk of Earth's autotrophs need aerobic respiration to survive.

Autotrophic plants use the energy from the sun and uncomplicated substances like carbon dioxide and water to store energy in food (glucose and starch). Instead of getting their energy from other living things, they get it directly from sunshine.
